Had my phone for a few months now and recently found that it can't connect to my secure network at home.
When I turn wifi on I get the dreaded connect/disconnect message while it constantly tries to connect to my network. If I leave it on then the battery will drain overnight while the phone tries to connect. I have an iphone which connects to the network no problem. As does my laptop etc
To try to fix this I deleted all my new apps, especially the push ones which give me news updates, etc but this has made no difference.
The weird thing is if I turn off my router's security then the phone will connect and works perfectly fine. I've tried using all the different security settings (even WPS) with new passwords etc and everything seems to setup fine on the phone except it just doesn't want to connect (or more accurately stays connected for a microsecond).
If I go back to an open network it connects immediately and stays connected.
I think this is the root cause of the wifi connection problems that many other people are getting. But I'm at a loss to try to understand why it won't pick up a secure network but works fine otherwise.
My phone is using 2.2.1 and has been rooted
Any thoughts?

Root the problem highly unlikely ..
Secure home network test .
Remove security from Router that is no password .
Remove that connection from phone .
Reboot phone let it pick up router and connect .
If it does then delete reset router password and add in phone .

Thanks for suggested fix. I'll give it a go and let you know if it worked.
Root was a bad choice of word..... I meant that while looking for a solution to my wifi problem I noticed many other people complaining that they can't connect to a wifi network for one reason or another and I was thinking that maybe broken security is a common cause of many wifi connection issues.. In my case there was nothing physical at all to suggest that security was an issue, especially since all my other devices work fine on the same network.
Cheers
Hi, tried your suggestion but I still cant connect. The first time I rebooted the phone it knocked out my internet connection! I've setup a static IP address for my PC and the phone was insisting on trying to connect using the same address and creating a conflict. I fixed that so that's not the issue.
This is what I've tried..
I checked to make sure DHCP was enabled in the router, rebooted everything. No luck.
I tried adding an IP Address Reservation for the phone and assigning a dedicated static IP Address. No luck either
I tried connecting the device using WPS. It all went as it should - my router saw the device, added the mac address to the list of devices etc. The phone acknowledged the handshake. But again it still wont connect.
I checked the router log and it says "DHCP IP: (192.168.1.2)] to MAC address B4:07:F9:336:3D, Tuesday, May 24,2011 03:08:48" which I think is what it should say.
OK I've just fixed it!!! Or at least its connected.
All along I've been securing the network with WPA2-PSK. I just changed it to WEP and the phone connected immediately. I hadn't considered WEP because I read that its not that secure and I do all my banking etc through my PC.
I've tried all the other security options and only WEP works with the phone. I suspect its a compatibility problem between the phone and my router (a Netgear WNT834B v2) because both the phone and router work independently but not very well together. There's plenty of posts discussing the Galaxy S connecting to WPA networks so it can do it.
Now, after trying all the other security options. It won't connect again even on WEP. Bummer. It is acting slightly differently in that its trying to acquire an IP address instead of simply not connecting, although it doesn't seem to be able to find one.
I need to try this on a friends network and see if the router or the phone is to blame. I've no idea... but the phone's a bit too touchy for my liking
I had a similar issue, I had to reflash the ROM to get it to work. Backup all your contacts and stuff and then do a full factory resetting. See if that helps, if it doesnt, reflash the ROM. It should work.
Well I've spent the last few days looking into this issue and it's considerably more widespread than I first realised. The problem is that while many people have a wifi connection issue we all seem to have variations on a theme.
As I say in my case the phone will connect and stay connected to an open network but won't touch a secure one. I tried many suggested fixes and nothing's worked so I am now trying a factory reset.
A couple of questions: there appears to be two ways to do this, a factory data reset through the phone menu; and a hard reset using a combination of volume buttons, etc. The hard reset seems to be the deeper of the two.
When you say full factory setting which one did you mean? I am currently data resetting and therefore using the "authorised" Samsung reset
But how long does this process take? My phone has had a black screen and been vibrating every 10 seconds or so for the last hour. It's getting quite hot and there appears to be no end in sight. Has the phone hung or something? If it has how do I get out of this without bricking the phone? It's beginning to concern me because I'll have to do something real soon.
As an aside, in my search for a solution I found something that might help someone people (it didn't work for me). According to the bloke who posted it, the problem for everyone is that the wifi drivers have not been installed properly and if you enter *#*#526#*#* on your keypad it unlocks a service access that reinstalls the wifi driver. I tried it and the phone told me the software was installed successfully but no change.
Waited long enough so pulled the battery out and restarted the phone. I get the startup screen but after that the screen goes black and it vibrates again every ten secs and I can't get in.
Have to try the other reset.....
Things are going from bad to worse..
Have managed to start a full factory reset using the volume, power and home button but it's gone back into the black screen and vibrating every ten seconds.
I know Im going off topic here but Ive now reset the phone, wiped the cache, tried to apply the sd card update (aborted because it can't find the directory) and it always comes back to the black screen and vibrating every ten secs.
Am now trying to reflash the rom. Oden reports that the flash was successful but the phone wont reboot. I tried a couple of times - one with Re-Partion checked and the other unchecked but neither will reboot. What could be causing that? I somehow remember that my firmware was JPH but I could only get hold of JPK. Could that be the cause?
I seem to have solved all the issues at last. Thought it was going to be a bit over my head for a spell.
Once I discovered that the only way I was going to get into my phone was by flashing the rom the first problem I came across was I didn't know which firmware my phone was using previously, apart from the fact it was 2.2.1 and from Asia. I guessed wrongly and after "successfully" flashing the phone it wouldn't reboot. I then noticed that there were only three variations of the 2.2.1 firmware for my region. The second one I tried went a little further than the first but I got an error message about the SD card. The third one installed no problem.
So I instantly checked the wifi signal and the phone connected to the secured network. And stays connected - so far about an hour and a half.
It's amazing how the phone deteriorated the way it did. Hope it doesn't do it again.
Thanks for any help/suggestions
Ok,
So, I, along with a few others, pay for the Unlimited Mobile HotSpot and want this app to work as other (root) tethering apps only allow Ad-Hoc.
Here's what I did to get it to work on my Windows 7 x64 Computer as of just a few moments ago and I do plan to work on this issue to get this figured out.
I've discovered that the /data/misc/dhcp/udhcpd.conf file is what controls the DHCP addressing for the 4gMobileHotSpot App. Within this app, I discovered (in the Modded ROM (as of now, I have Gingervolt1.1)), that the "Option DNS" addresses were completely wrong. This was apparent from the get go as they were internal IP address starting with 192.168.x.x.
The steps to get this app working on Windows is:
0 - Be Rooted (Sorry, just had to point the obvious out in Step 0)
1 - Use the market and download/install the Text Edit (Paul Mach) App
2 - (TESTed and Working), Use AntTek (root) Explorer and navigate to:
/data/misc
3 - Long Press the udhcpd.conf file and select to open with the Text Edit App
4 - Change the 'option dns' from 192.168.x.x to 66.174.92.14 69.78.96.14 and save/exit
5* - In Windows, set the IPV4 Properties to:
Use Following Address:
IP Address: 192.168.1.5 (or anything in between start and end range in text file)
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.1.1
Use Following DNS server addresses:
Preferred DNS Server: 66.174.92.14
Alternate DNS Server: 69.78.96.14
6 - Start 4gHotSpot App
7 - Tell Windows to Connect and you should be connected.
NOTE: It is late and I know that this will become clearer as time goes on and since I have to work in the morning, this is the best I came up with in a few minutes after figuring out that the hang up was with this file, in which I knew it's been a DHCP issue all along. Why this file is changed with the Modded ROMs is beyond me and I doubt MT changed this, so likely it is something to do with the DE-odex or some other modification of this app and it's initialization. Just deleting the CONFIG file will only cause it to write a new one with the wrong values again.
For those who do use this app, it is known to stop responding at times and I am going to look into that. I'm thinking this is a DNS issue and will try some other DNS Servers (8.8.8.8 I believe is a Google public DNS)..
In the meantime, this is a start for anyone to add to this that has more DHCP/DNS/Network experience. I don't have another android device handy to test the connectivity, so will have to get that figured out.
Key point here is, is that the 4gHotSpot App gets corrupted with the Custom ROMs and for some reason sets up wrong DNS servers in the Config file.
Hope to see some thoughts, additions, fixes, to this problem with this being pointed out, from others. I will continue to work on it throughout this next week after work.
Last Note: The DNS server numbers came from the original Config prior to rooting/modding. Also, I do know that is it redundant to have them in the config file AND the Windows Properties. It's just that setting Windows to 192.168.1.1 (option router in the Config file) didn't work. Again, will work on cleaning this method up and simplifying.

Thought I would give this a try today after re-rooting. I had no luck getting connected with the 4g hotspot app.
On my phone the file was in /data/misc/dhcp/ and the values were already correct in the file.
I tried changing the dns to a public one and back - neither worked.
I tried moving the file to /data/misc and it didn't work.
My ipad seems to connect ok but hangs trying to lease an ip address. Reloaded v6 tot and upgraded to non-rooted gingerbread and the app works again.
Is it possible you changed something else?
I'm glad it's working for you. Wish I could get it working as this is the only thing keeping me stuck on a non-rooted phone.

Ok, so here's what I did after reading your post:
1 - Corrected the path (Sorry, it was late and I missed that /dhcp portion of the path).
2 - Deleted "option router 192.168.1.1" from udhcpd.conf file
3 - Deleted "option dns x.x.x.x x.x.x.x" from udhcpd.conf file
Set Windows up with the Following:
Static IP : 192.168.1.2
Subnet : 255.255.255.0
Gateway : 192.168.1.1
DNS Servers : 4.2.2.1 & 4.2.2.2
That worked.
So, what I am seeing if I try to use DHCP on Windows is that the 4gHotSpot gives the computer 192.168.16.x addressing even though the config file is set to give out 192.168.1.x addresses (x=2 through 254). It also gives Windows 3 DNS servers that are local IP addresses and will never go anywhere.
What to do now? Figure out what is being changed with the Custom ROMs that is causing the app to act like that. In fact, it will act like that when I restore back to Stock GB Rooted via restore from backup in CWM, but I have yet to test deleting the config file and restarting 4gHotSpot to test. I will do that over the weekend as I don't have a lot of time I can have my phone down during week. But I do plan to up to the GingerVolt1.3 tonight.
As of right now, I am using my windows machine connected to the 4gHotSpot App to write this post. Also, I don't know about the iPhone/iPad and possible settings. If you can Force (Set a Static IP) then follow what I did up above, but you will also need to set the DNS servers and not sure you can do that on an Iphone/iPad.
The DNS Servers I listed are found on a public list and are also said to be Verizon DNS servers...
The other problem I found and is an issue with the app, is using auto b/g/n will cause the hotspot to lose connectivity. When in that mode, I connect at 65Mbps, but it drops down to 6Mbps and stalls and fluctuates. I set it to 'g' only and get a SOLID 54Mbps connection just like the tether apps.
SPEED TEST Results: 18.35 Mbps Down, 10.66 Mbps Up without a glitch.
Obviously this app works with DHCP addressing as STOCK. So, I will begin my Android Development with figuring out one of two things. Either get this app to work as it's supposed to, or create a root app with 'Infrastructure' based on whatever I can find in the coding for this app if I can figure out a way to decode it.
I personally hate the idea that you can't connect other android devices to AdHoc and also annoys me to have to manually connect Windows since it doesn't seem to have the ability to automatically connect to AdHoc Networks. Linux does perfectly fine with auto connect AdHoc, go figure. Android is Linux Based, yet can't AdHoc, but provides an AdHoc as an access point for other devices. weird, lol.
Let me know if any of this helps, but do know I am going to continue to figure this out. I'm sure de-odexing the app had something to do with it as I'm sure Verizon did their best to keep this app from being hacked for free HotSpot service.
-Cybie
Thanks for the detailed response.
I'm going to try again. I won't be able to try until tonight or tomorrow morning when I have time to play with it and roll back if necessary.
I'll let you know if it works or I find out anything else.
Before you install a ROM and have the app working, try connecting your computer and get the values (ip, dns, gateway, etc.) That the app dhcp assigns and post that. Rooting the phone alone shouldn't break the app either. By getting those values posted, would help and also save me from downgrading just for that purpose. Knowing that it works with without a mod is one thing,. So my focus is working on getting it to function with a modded ROM.
It's strange that i can get the app to work if i force the connecting device to values (static settings), but this doesn't help with certain devices and needs to connect via dhcp.

These number are from your connected device? What device are you connecting that give you such numbers? I'm not familiar with the iPad and how it displays connection details. Is that what that is from?
I'm still able to connect after updating to GingerVolt1.2 and manually installed 4gHotSpot app. I just got home with little time to work on this project for the night, so I will update what I can if any changes in getting things to work.
-Cybie
those numbers were from an ipad connected via dhcp.
I'll see if I can use a laptop at work today to see the values I get connecting from a laptop. Should be the same I would imagine.
I will retry rooting the stock rom tonight and see what happens.

Sounds good. Those numbers will help.
I will add, though, that someone posted a way to get the wifi tether to work with the Revolution, here in the forum. The problem, though, is that it's connection via 'n' mode, which would be great, except it drops out. If you try to download something that's fast (or going to speedtest sites), you will find that that happens and what everyone is complaining about the HotSpot app not working. All that needs to be done is changing it to 'g' only mode and a solid connection.
Anyhow, I will see if I can figure out how to get that app working on 'g' only mode also, and if I do, then I will just use that app instead. Otherwise, I plan to continue to figure out the 4gHotSpot App
-Cybie
Cybie,
Glad to see someone's tackling this...I don't suppose your work here could be applied in a way that would make this app work for those who don't pay for the mobile hotspot?
I am waiting on a replacement Revo to arrive in the mail, should be here tomorrow or Saturday. Any values I can pull that might be of use to you before I get happy with flashing roms, rooting, etc?
I find that the OpenDNS nameservers tend to work pretty well everywhere I use them, if you wanted to give them a try:
Primary: 208.67.222.222
Secondary: 208.67.220.220

Sorry for the delay. Been working extra hours at work and haven't had the energy to do much with this past couple days.
Anyhow, no, I don't intend to try to get it working for those who do not pay. Why? There are apps out there for this and the only reason I was trying to get this to work properly was for the fact that it would be nice to have the proper connection for those who do pay. I say that because the HotSpot app actually has a faster wifi connection (using n mode) than the tether (root) apps out there, with the exception of the one posted at:
http://forum.xda-developers.com/showthread.php?t=1339150
Unfortunately I am having the same issue with the HotSpot and that app (using infrastructure mode) when connecting. They both to link up at 65Mbps. In fact, I got 72Mbps with the wifi Tether app from the link, but like the HotSpot app, I have issues with the connection dropping out using 'n' mode.
The HotSpot app will allow you to set it to 'g' only mode, though only get a 54Mbps link speed, but sustains a solid connection with no drop outs. Others say they don't have that issue, so it may just be my wifi adapter??? I am going to test it on my laptop, but if I remember, I did have that same issue with the laptop, so maybe it's just my phone??
Either way, I am going to be doing what I can to get 4gHotSpot to work correctly with rooted/modded ROMs. Strange thing is, rooted, it still works fine. After installed modded ROM, it fails to work. And if I restore back to factory rooted via CWM, it still doesn't work. You actually have to restored/flash back to total stock. After that, you can root with it working, but not after installing a ROM.
-Cybie
Any luck with the fix?
OK, so I read that your hotspot worked fine after rooting, but stopped with the ROM was changed.
I rooted my phone yesterday, using the one button method. I have not modified the phone beyond this change. As far as I can tell the only functionality problem I have is with the hotspot.
The tether method continues to work (as I am using it right now). The hotspot does make a wifi connection to my devices but there never is any received data from the network.
Please help, any ideas on what I should look at or change?
Thanks ahead of time.

I've noticed something very strange with the HotSpot and Rooting.
If you root, the HotSpot continues to work. But, if you reboot after rooting, that's when the failures begin. So, I am thinking that the files are being overwritten. I've been able to test with clean root, root with tether app, and restore without root.
Without root, the HotSpot continues to work fine as I have been using it for the past two weeks as I need it for my new WiFi Tablet. There is the WiFi app the allows for Infrastructure, but that also allows devices to connect via N-Mode, where I have issues of the data dropping out. Forcing b/g only on my HotSpot app, I have very reliable service.
I am planning (after my trip) to root my phone, copy some DHCP files before ANYthing can be changed and before rebooting. Comparing these files and seeing if anything changes there. If so, that will allow me to create a simple app to restore these files back to stock, either automatically, or through 'starting' of the app.
I haven't forgotten about this issue and It's something that I am needing to figure out. The problem is time right now. For the past few months, I had to work a job in order to keep bills paid. That job took a lot of my hours I used to have to figure things out. I am going to be having limited time available, but do plan to work on it some more in the next few weeks, especially since i want my Tablet to work flawlessly with my phone, as that is my ONLY source of internet and I DO pay for the HotSpot service.
-Cybie
Thanks for the update.
Like you I also pay for the 4g hotspot. I jumped on it when they offered the unlimited for $30.
Now that I've tried the gingervolt rom and the supercharger script I don't think I can go back. It just feels like a totally different phone.
I haven't had as much need for it recently so I haven't tried one of the other tethering apps.
Thanks for plugging along on this.
Yes, thanks for looking at this.
Here is some more observations:
Using your set ip and other setting I can get the hotspot to work. Two of my devices are not able to set a fix address without rooting them. So they do connect but only my PC will download a web page.
Here is the address my Revo is setting on the other two devices: 192.168.16.30 and .31.
Ok, so here's an update to this issue.
I have tracked the problem down to a failure to write to the udhcpd.leases file within the /data/misc/dhcp folder.
So, I did some searches on the net about a few things, but there's not much information regarding the "paid" HotSpot feature vs the (Root) Tether Apps.
What I did comes across, though, is there seems to be some sort of issue with certain versions of busybox relating to the udhcpd.conf. I also found the file that gives the 192.168.16.x addresses. But, by the time I found it, the phone already goofed up the HotSpot app settings and things weren't working. So, next round of factory restoring via LGNPST/Tot, I will seek into that and see what I can find out.
It's weird that the 4g HotSpot app will work flawlessly on the initial boot (Rooted, ROM'd, and even OC'd). But, after a reboot of the phone (once or twice), it becomes corrupted and non-working. It's going to be related to some sort of permissions issue and some file that is able to be corrupted/changed with the root/superuser access. I had similar results with fresh restore and JUST root, so the ROM's have nothing to do with it as far as I am concerned at this point.
In case you might ask. I Refreshed phone to total stock, rooted, and then, all at one shot, installed Gingervolt 1.3, OC, and Hotspot before rooting phone. HotSpot worked fine until the next reboot, where it did work for a few minutes then Kaboom! Nodda.
If someone can access (pull) the /system/var/lib/misc/udhcpd.leases file from a fresh stock phone, or even first-time booted, rooted phone, I would appreciate that as this file may be something in question, but my file was already changed by the time I found it.
-Cybie
I love to help but mine isn't working either. Can you get me started on returning the phone back to stock? I did install a backup util, and ran it first thing after rooting. But I am guessing that wasn't soon enough.
I will take a look at the file I have, I will try the two viewers I have, not sure if they will work.
I did run a restore, and the hotspot did work afterwards. My signal is very weak -110 dBm right now so if you can tell me how to copy/view the file I can get it for you (I did check my tools and could find the file but could not view it, I tried to email it to myself but the encoder couldn't handle it).
By the way, are you aware of a bug in the hotspot, tethering. When you turn off the hot spot and start tethering the hotspot comes back on and tethering will not start. It take a phone power turn to fix it.

EDIT: When you copy these files, Don't view them until you zip up a copy first. They could potentially get corrupted. not likely, but with the way it's going with this 'project', who knows.
adb pull /data/misc/dhcp datadhcp (This will copy files from phone to a created directory called datadhcp)
Also, and more importantly, this is what I am really wanting:
adb pull /system/var/lib/misc varmisc (copies to created varmisc folder)
AND
adb pull system/etc/dhcpcd dhcpcd (copied to dhcpcd folder)
The created folders and files will be in the same 'dos' directory you have adb in. You can use the folder in which the all in one root is from MT if you are wondering where to get that by any chance.
Those would be a big help in getting thing figured out. At least, if those are the culprits.
NOTE: In order to have non-corrupted files, these have to be pulled from a fresh restore via LGNPST / Tot method. A restore via nandroid backup will not work. those files, once corrupted, seem to remain so, even after a restore for some odd reason, unless you were lucky enough to not have them corrupted prior to backing up, which would likely mean you rooted, rebooted into recovery and backed up before rebooting into your phone.

Please clarify on this. Are you referring to starting the 4gHotSpot, shutting it down, and then starting a (root) Tether App??? If so, I haven't really had that issue because once I have to use the root apps to tether with, that usually means my HotSpot won't work at that point. I will say, however, I have had an issue where the HotSpot didn't want to shut down. I just go into Services/App Management and force a shutdown instead of a reboot. A bit quicker....
-Cybie
I will take a run at copying this stuff later today.
On the hotspot bug. Even before rooting, or upgrading to GB there was this bug, and it is still there after GB.
Once the hotspot has been started and then the user shuts it down it appears to shut down. Then the tethering (the application that came with the phone) is initiated it looks like it is tethering but the hotspot icon comes on after the phone has finished tethering and indeed it is running that way too.
I tried this five time last night: Restored the hotspot both application and data (titanium app), installation part of the application would fail but T said it was complete. Launched the application and two of the five times the PC had the correct IP address, the other three times it had the corrupted ones. Also when the PC did come up correctly the second device's IP address was corrupted. So I may need to fiddle a bit to fine the uncorrupted files after restore.
Perhaps someone else could help with copies the files too?
A few days ago I ran into a problem. My wifi wasn't connected when I turned on my tab 8.9. When I try to connect to my own network, and get into the settings page, the option 'ok' is greyed out. This means that I can only 'cancel', and in that way not connect to my own network anymore. The same thing happens when I try to connect to another network. My device is not rooted, running 3.2, and it is running the most recent firmware. Restarting the device didn't solve it. Any thoughts on this one?
Bump, same problem, or at least similar.
Android Version 3.2
Kernal Version 2.6.36.3 ([email protected] #1)
Build Number HTJ85B
Wireless works on some networks and not others. B G N do not matter, it is random. Still running stock ROM, not rooted. I have tried reseting OS, no luck.
What it does it it finds the network, tries to connect to the network, fails, remembers the network, and the cycle starts over.
Hi guys,
do you get the 'Obtaining IP address' message when connecting? mine does that constantly on some networks, it gets stuck in a loop and simply will not connect. I've found out that this is due to the tab remembering an IP address it used to use and trying to re-use it every time it connects. That is of course not always possible and so it tries - fails - tries etc.
The way to fix this apparently is to delete the dhcp_list file which holds the remembered IP addresses, only issue is that I cannot find that file anywhere. I'm running AOSP Galaxian Soup on mine with motley kernel, my home wifi works ok (probably because the same IP address is available all the time), work wifi doesn't want to work at all.
Maybe one of the devs sees this and can shed a bit more light on whether the solution is correct or not.
Regards,
dsc.
I was eventually able to solve this in a very easy way. for one reason or another the tab only wanted to log in when the password contained a capital, so I changed the WPA preshared key to something that contained a capital and a number and it was working again. very strange, because it had been working perfectly for about two months before this problem occurred. hope this helps.
Hi,
I managed to fix it by selecting static IP. I've seen this suggested a couple of times but when using the tablet in horizontal position I could see the static/dynami selection. Turns out you have to rotate the table to vertical position to see it.
Regards,
dsc.
Thanks for the discussion. my main problem is that i can't set a static at my work network. it will work at home, but i NEED it to work at both, otherwise it does me no good. I will keep banging my head against.
I will check back to see if smarter people come up with a solution, and if i come up with somthing i will post.

This is my problem exactly.
Hi,
not sure if you've seen this (I think the original solution comes from here anyway):
[tried posting an url but it was blocked, try googling:
'Tab cannot get IP address for WiFi problem + recs'
and scroll down to zakaria's post]
Some people suggest trying static, even if it fails it might delete the previously stored IP address that the Tab is trying to connect with and get a new one which should work. What I did was connected to the Wifi with my laptop, checked the IP/DNS details and after slight mods used it on the Tab. I did try setting the static to something roughly correct, connecting and reverting back to dynamic, but it wouldn't have it
Regards,
dsc.

Have you checked with your work network whether or not it needs ca certificate?
or you could try to download wifi ace (advanced config editor) from the playstore, and set the settings from there
As title says, For first startup, can I skip selecting wifi connection for now and go forward? Wifi is disabled in office and I cant wait to check out the device until I reach home

After I rooted my N7, I didn't have wifi available at the time. After struggling trying to bypass the wifi connection screens, I just let it sit for a few minutes. When I looked back at the tablet, it either had moved on, or gave me the choice to bypass the wifi setup for now. Either way, it worked.
I had no problem setting up wifi later on when it became available again.
Tap all the corners in a clockwise motion, starting with the top-left. Give it a good solid tap or else you'll be going 'round in circles a few minutes.
One good rotation should dump you at the homescreen. I HIGHLY recommend not getting fancy with it and setting it up properly when you get a connection. If you don't connect it to your Google Account at startup, some things get funky later on. Play around then factory reset it when you get to a good wifi spot.
This is also a great time to just go ass wild with games/apps/widgets/etc just to try them out. Then factory reset and install the ones you want (no residue). I always do that with new devices (even the iPads).
Sorry mate, that stroking four corners idea didn't work. I just tricked the startup logic using a wifi router (without any internet connection), connecting to the network and just skipping the google login. Later used Bluetooth DUN to login into the google account.

This worked for me as well - thanks for the suggestion.
[HELP] Wifi & Bluetooth gone, no longer functioning (Found BT AND Wifi MAC in CP!)
Just throwing this out there, I've actively used the hell out of my Thrill, and flashed it many times. However, the Bluetooth went out on AT&T's v20p, and Wifi went out after an OC'd crash. I was just wondering if there was some way to reset the chip itself as it seems the on/off for both do nothing, each stays permanently off now. I really want BT back, but I NEED Wifi back... Can somebody help?
I have flashed back to V20P in an effort to get both Wifi and BT working again, but still dead. I will sit on V20P for now, and hope things work eventually.
Trying to enable Wifi comes up with "Activity Wi-Fi settings (in application Settings) is not responding." leading me to believe that the hardware has to be fully reset.

Have you tried a different firmware?

I've tried V10K, V10D, V20A, V20P, V21D, and V21E, none of them restored the bluetooth (original issue), and so far V10K, V20P, and V21E have not restored the Wifi.
On V21E under settings, it's always showing as "Turning off..." under Wi-Fi. So it's definitely a hardware lockup. Is there anyway to do a full hardware reset on these things? I don't care about opening it, I'm not with AT&T anymore so the phone is mine, and frankly, I just want it to work.
I'm thinking of following some of the instructions for the lost IMEI, see if redoing the Communications Partition restores/fixes the BT and WiFi, I know stuff is getting corrupted when I crash while OC'd, and that's the only thing I haven't touched. I'll try it here tonight and see what I get. I still have both my WiFi and BT MAC addresses (WiFi stored in my router, BT in my computer when it was paired). So... I'll be trying that out soon as I get home today. Think it'll help?
So after fiddling around, I followed these steps from the reset your IMEI/SIM Unlock your phone thread, and started inspecting the CP payload that had to be flashed. I found a couple settings that I think people might find interesting:
1. Connect phone by USB
2. Activate USB debug mode
3. Enter 3845#*920# in dialer if that doesn’t work try 3845#*925#
4. Select Port Settings -> Select CP Image Download
5. A new device should appear at let it install
6. Open Tutty and select serial protocol. Click on open
7. Type AT if response is not OK, change port number (it is possible that when typing you don’t see any letters)
At this point, in order to check your Bluetooth MAC address, type AT%BTAD, this should display a string of 12 hex characters. IF you need to change your BT mac (such as putting it back in like I had to), use AT%BTAD=123456ABCDEF where "123456ABCDEF" is your Bluetooth MAC address (I had mine saved in my computer).
For Wireless MAC address: AT%MAC, same thing if you need to change it AT%MAC=123456ABCDEF. So far this has NOT restored my Wifi or Bluetooth, however it MAY help others who have suffered this loss. You will only need the Flash driver from that thread and tutty, so download the IMEI tool package, but don't worry about the CP unless you absolutely need it. Also, this is great to replace those MAC addresses once you flash (as they're likely wiped with the entire CP wipe).
I'm requesting some assistance with getting my Wifi and Bluetooth operational again if possible, maybe it's kernel modules, I'm not 100% sure, however, in the debug menu (3845#*<MDLNM>#) there is logging options for certain sections of the system. I'll be more than happy to provide logs if requested, I just want my Wifi and BT back and I feel like I'm onto something maybe. Here's to hoping!

What ROM are you currently on? Baseband as well.

Currently running V21E baseband & Prometheus ROM v1.5, I've managed to make the phone stable again, however still no Wifi or BT. Inside CP, AT%IMEI, %BTAD, and %MAC show correct, thanks for the assist.
If I was on AT&T, this lack of Wifi would be absolute murder, but thankfully, T-Mo's got 5GB of 4G so I can still use my phone, just not half the apps (like Netflix (it checks Wifi status and locks up), or XBMC remote).

I would say that you should try going back to FroYo and checking those addresses again.

I've gone back to FroYo without any change to Wifi or Bluetooth, but I'll go back to V10K and check the CP again.

Please Explain Tutty. I get into the hidden screen and tried the download and nothing was downloaded, this is my first smartphone and do no that there is no MAC address for the bluetooth device. it is the only thing not working. Thanks in advance for the help.
