I have had my Tab for 2 weeks now.
At home I had no problem to connect to my WiFi network for 1 week: then suddenly the Tab would not connect and would remain stuck on “getting IP address…”.
I changed from WPA to WEP to WPA2 PSK with no luck
But if I go to a static IP, then I have no problem to connect.
On my office “public” WiFi network, exactly the same problem: it worked for a week and then bingo stuck on “getting IP address…”. Again going to static IP solved the connection problem.
My question is: how do you delete a network from the list? It seems to me that the Tab keeps an IP address in memory and if ever that address is taken by another device, it gets stuck!
Any advice would be appreciated.
I had this exact same issue on the same day I bought my Sprint Galaxy Tab (11/14). I did a hard reset that afternoon, and I haven't experienced the issue since. I'd already had all of my apps downloaded, and settings tweaked, so hard resetting was kind of annoying. I hope this doesn't come up again.
Yep sounds familiar, my Thomson Speedtouch 780i runs on a old firmware which gives me same issue with the Tab, had to run with no security. If you decide to run with no security turn off broadcasting..or update firmware/router..
My router is quite recent and has the latest firmware.
All my toys (iPad, Dell Streak, HD2 together with 3 PCs) connect without any problem.
The Tab had no problem either for a week.
Then for unknown reason no way to connect unless using a static IP.
And as I have not found a way to delete the network in memory (short of doing a hard reset)I am stuck.
And now same problem arises with office netxork:-(
Yeah just do a factory reset in privacy settings i think

My Tab is doing the same thing now. I can't do a hard reset....is there another solution?
Ugh, I have the same issue! Had it for 2 days and all of the sudden it's stuck on Getting IP address from... Resetting to factory defaults was depressing. I wish there was another way!
It also happened to me when I was on vacation at my relatives home. The tab would work for a day or two and then be stuck at that message. I had no issues with doing a factory reset as it was still new. But then I started using the static IP trick and that worked. Now I'm back at home and I don't have this issue at all. Been using it for a week with my wifi and all is well.
Nothing was actually working: restarting the router, forgetting the network, creating the network manually, changing the authentication method, etc.
I'm sure its was an issue with the router at my relatives home, but still why was my Nexus one and Laptop connecting with no problem???
For those who are having the problem, use a static IP for the time being, you don't have to reset.

I ended up switching to Channel 1 on the router at home, and haven't had any problems since. Chose Channel 1 after running WiFi Analyzer.
having this same problem. I've messed with WEP vis WPA and tried static IP. Using a verizon fios router. any help?
Bah, it happened again! Now I really dont want to reset
Same issue here ...
I can get WIFI at Starbucks but not at home ( Open-WRT on linksys )
I wonder if it depends on SIM card being inserted?
Mine is a Verizon FioS router as well, at work. Can get on fine at home or anywhere else. My iPad had a problem here forgetting the network but I could at least reconnect. This is doing exactly like you guys.
I wouldn't even care that much except when I'm inside the office I can only pull in Edge data. Ugh.
I had to change wireless settings on my Linksys - most changes were to disable some fanny things like "afterburner" - and setup wap2 for security to have a stable wifi.
I've had the same problem with my TMobile Galaxy Tab. All I do is to turn off Wifi in the Settings app, then turn it on again. I am usually able to snarf an IP address straight away after that.
It also helps to just turn the device on and then off again. it boots so fast that it isn't too annoying.
I had similar problem at home. My DHCP server had wrong time set. After setting the time on DHCP server correctly everything is back to normal.
i hav a tab on tmobile love it not sure if i had the same issuse as u guys tho the issuse i had was it would work without any problems im talkin about wifi then the next day the wifi doesnt want to lock onto the wifi it would search then drop to start serchin again , now wat i learned is sum apps require wifi to work because high data at the same time it changes sumthing in ur wifi settings after using the app the first time which would require u to master reset the device to resolve the issue the program that was doin it for me was frostwire
same here
my version of the same problem appeared when i changed the static IP of my home router (AVM Fritz!Box 7170). before that i always got a dynamic IP through DHCP on my galaxy tab.
After changing the router IP i only could connect with a static IP.
if i use a different WIFI network instead, DHCP is working as expected.
in my opinion the problem is with the firmware storing the network settings and with no possibility of deleting it completely. a hard reset cannot be the solution...
does anybody of you know if this problem occurs on other froyo-based devices also? is there a way of deleting network settings in a working way?
Had the same problem, EU TAB white Stock 2.2 rooted spot connecting to my main Wifi but connects to 3 or 4 other dhcp APs.
Have a htc Desire whit stock 2.2 + rooted and never had that problem.
In the end i hardreset Tab and no problems 1week and counting.
EDIT
FUuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu
Happen again... im not going to hardreset again, im looking for a more permanent solution
Had the same problem. I have the Verizon FIOS router. The solution is actually easy. Just drain the battery of the Tab. Charge it to full and turn the Tab on. I think the Tab really "forgets" the old network after this kind of restart. No need to reset your Tab to the factory settings.

i have a linksys WRT54GX4. When I try to connect to it using the xperia, it tries to connect for a few seconds and then the status shows unavailalbe then a couple seconds later the status of the router goes back to available but i can never connect to it. The router is running a DHCP server and the wireless security is WEP 128bit and the authentication is open. I don't know why it doesn't want to connect. I really need to sort this out. Anyone else experience this problem? The phone connects to other routers in my neighborhood though, so it might be the router, but i have other devices connected to the router and they are just fine.
Haven't used that router before but maybe you could try updating the routers firmware to the lastest available.
These should be available from the manufacturers website.
already tried its the latest.th erouter isn't giving me any problems on my othe computers/ laptops. Is it possible that the x1 just isn't compatible with it?
Do you have any other security, i.e. MAC filtering, turned on?
no i never mess with the more advanced settings. BTW I even tried disabling all encryption basically unprotected, and it still gave the same problems! Thanks for the quick replies also.
Hmmmm......
Ok, I know its a pain but try changing your security from WEP to WPA.
Everyone with wireless should really use WPA or above, WEP is quite crackable with various free tools floating around the net.
yea but shouldn't it have connected with NO encryption whatsoever?
Hpoefully a hard reset will fix your problem?
I had the same problem but i thougt it was becuse ny router but i tried to connect to other networks aswell an got the same problem, well later on my phone stopped accepting files thrue the usb cable. and didt want to install some cab files that i had istalled before and knew was working.
I had enough and decided to hard reset it and it really fixed all my problems.
so hopyfully it will for you too..
Good luck.
yea i'm gonna try now, hopefull that will work, did u hard reset thorugh the iption in settings, or did you do it physiclaly through buttons>?
Havent had that problems ... what i do is allow only my devices mac address to connect ...
my psp as well as gf psp
2 desktop + laptop
htc touch cruise
xperia
and home media player
Everything else gets denied, cant really beat mac address filtering.
ok just tried a hard reset and still didn't work. The signal strength is full but the phone never even gives me that automatic message that there is a network available, but it does this for other routers in my neighborhood.

Actually, you can, but that's for another forum
OK PROBLEM SOLVED. Did a factory reset on my router, then the phone connected. But when I went to change the channel from auto to 10, the wifi stopped connecting. After that, any susequent changes to the channel; whether I tried a different channel or set it back to auto, did not work and the only way to get it back was factory reset the router. So basically I have resseted my router, and have not touched the channel settings and it is working fine. BTW the dedicated Xperia tech support line is AWESOME, even though they weren't the ones who figured out why i had the problem (and they wouldn't have because it was the routers problem) they knew what they were talking about and are actually from the US!
n4v1n, did WiFi work for you in other networks (with other routers)?
I have the same problem with my phone: only reset of my house router allows the phone to reconnect.
I am not so convinced that it's a problem of the router, because two of Samsung phones (Omnia HD on Symbian and Wave on Bada) connect always without any problem.
does your router have a physical easy connect button? try to use that before connecting even you already have the proper setup on both devices. sometimes somehow that happend to laptop, phone, wifi card. and with a single push solved most of the quirks.
if i remembered correctly, older wifi support only up to 7-1 devices. and my phone seems never connect to anything higher than channel 6.
Well I've had my Captivate for 3 months, and up until now it's been smooth sailing. Two days ago I came home and my power was off, and when it came back on I tried connecting to my router like usual, but now it won't connect. On the "wifi settings" menu it just says "obtaining ip address from..." for a few seconds then it says "disconnected" and goes back into "scanning..." mode. Also, under the "wifi networks" section it shows my network as "Disabled, secured with WPA/WPA2 PSK". (I am using a Linksys WRT54G with WPA2 security f.y.i.)
I've tried "forgetting" the network, I've deleted the whole file that remembers your networks, I've tried connecting via WPS button, I've double checked my password, I've power cycled my router, I've reset my router back to default and re-configured it...still nothing. It connects to the wifi on campus with no problems (in 4 different buildings), so obviously there is something wrong with my router setup.
If anyone has any advice on how to resolve this problem, it would be much appreciated!
**Also, I forgot to mention I am running Cognition v2.2 Beta 6

Happened to me a few times. Only way I could get out of this was to restore to a previous backup, or install fresh again. By the way, I experienced this problem only on 2.2. Never happened on 2.1.

Unfortunately I don't have anything else with wireless to test.
Elaborating on the issue
I've encounter exactly the same problem described here.
Samsung Galaxy S I9000. Froyo (official version). Not rooted.
Now it is the first time it has happened, and still I have not found a solution (restarted the router, restarted the phone and made more tests).
Before the upgrade to Froyo it has never happened. After the upgrade it worked ok for several days untill now.
Several other deviced at home are well connected to the router.
Its just s stupid suggestion maybe... but have you tried to change channels with your router?
Sometimes is just a stupid channel issue....
I found out the answer to this problem. I had to connect using static addressing. It seems at some point, the captivate 2.2 roms get confused for some of us and it starts trying to assign an IP address already used.
In my case, I tried everything... rebooting phone, router, ect.
Laptop connects fine, Wii connects fine...
But, I decided to connect via static addressing... BAM connected perfectly and instantly.
Connecting to other DHCP networks seems to be hit and miss as well.
So, I'd suggest reflashing might be the overall fix. But if you're like me and cannot reflash right away, try static addressing till you can get around to it.

Awesome! This sounds like a promising solution, thanks. Yeah I need to reflash soon anyway seeing as how Cognition is up to 2.4.x already...
Probably won't be tonight, but I will do this soon and let you know my results.
Alright, I have typed just about every keyword into google relating to setting up my router/phone to use a static IP and for some amazing reason there are ZERO results that have any information whatsoever about setting up a static ip on a phone. This is really frustrating, so if anyone would be kind enough to explain how to do this or link me somewhere that does, that would be awesome
go to your wi-fi settings and click the menu button.
it should pop with a "scan" and "advance"
click on advance and scroll down to "use static ip address"
then i guess you have to put in your network details, not sure on the details there cause i have done it but experiencing same problem with my galaxy s
power went out and now can't connect to my network
Edit : Possible fix
I just managed to connect to my network.
I put the device in flight mode and restarted my modem at the same time
put it out flight mode and pluged in the modem again and now works.
Hopefully that works for you to guys.
Yea, works perfectly. I have my laptop connected to it right now. I usually have to reset the phone to get wifi again.
edit: I set it to static ip, but then i got the same problem. Except now google search engine works No webpage opens, youtube app didnt work either.. only the search engine worked.
Well my phone must be in a good mood today because it just decided to start working again all on its own! I don't know what caused it...I have actually had both my phone and computer constantly on since this started happening. So for now I'm keeping my fingers crossed and hoping it doesn't mess up again.
This is probably just for me, but this isn't a viable solution.
The ONLY router I seem to have this issue with is the one that Verizon gives all it's FiOs customers. It's the Actiontec M1424WR Router/Modem. I know my WEP key is correct because it works just fine on all the laptops and other phones (a Palm Pre and another Captivate on 2.1). It tries to obtain an IP address for about 5 minutes and then just sits and says disabled. Does anyone know if there's a way to dump the DNS cache or whatever like you can on Windows?
Add me to the list of ones having this problem...guess I'll try to reflash everything in a bit to see if that fixes the problem.
Just an update I backed up everything using Tibu and then just restored it and my WiFi problem went away.
Mine is stock and just started having this problem....will connect to other wireless routers except mine, really pissing me off!
I've tried many times having the the phone "forget" me, then put in my password(which is correct)...same thing over and over.
Same problem here
I have a galaxy s and the recent update to froyo brought me the same problem already described here.
And the "funny" thing is that my router doesn't have an Static IP option, it's a simpler router from the cable provider.
So i'm trying also to find a solution to this. Two days ago i changed the wifi channel and it worked. But today i have again the same problem and changing the channel don't work anymore.
Each time i find a possible solution, it only works one time.
This is really annoying me. This must be a froyo bug, 2.1 never gave me this problem

I just bought my Samsung galaxy S i9000 and the only problem i have is with the WI-fi,it works fine until i reset the router(just power on and off), then it starts doing obtaining "IP adress from..." and it wont connect ever again .The only option in this case is to reset the phone to factory setting and this is frustrating.
I noticed that if i turn off the wi-fi on the phone first and after that reset the router and then turn on again the wi-fi on the phone works.The problem is sometimes i forget turning it off from the phone or if a power cut happens it will do the same thing until reseted to the factory settings again and of course i lose all the applications.
Any suggestions are welcome.
Thanks in advance.
Try to change the wi-fi name to something smaller.Also if you use password for the wi-fi try to deactivate it to see if it is the same problem.I feel that it has something to do with the decreption used in the router...maybe i m wrong..
I will try the password removal to see if the problem persists.
Nop, it doesn't work either way, i called a neighbor to come by with his nokia N8 and it seems to work fine for him.
By the way my IP changes every time if i power on and off the router i think the problem might come from there since it says "obtaining Ip adress from...", but then again for nokia N8 works just fine, and i even renamed and reseted the router to different settings and still doesn't work so my guess is that the phone has a problem.
Your router changes IP every time you restart it? Can you explain a little...are you being re-issued a dynamic IP from your ISP thats refreshes when you reset your router? Otherwise I would think even after resetting your router it would default to 192.168.1.0 or .0.0.
Either way it sounds like a DHCP problem...where the router is not properly issuing an IP address to the phone, or your phone has cached old settings and isn't being able to pick up an IP after your router changes IP.
Yea Kops the Ip is dynamic and refreshes every time i reset the router

I would look into seeing if your router is capable of NAT (as most routers are). This would enable a private network in the 192.168.x.x range, and might solve the issue of it not picking up the new IP if the issue is with caching the old one. As far as clearing any cache related to wifi, I'm not exactly sure where that would be found. You could try going into your Settings > Wireless & Network > Wifi settings and forgetting the network. Doing this and letting it re-discover it may help.
May I ask why you are resetting your router? I see no need for it to happen very often. Also, just let me clarify....if you successfully join the wifi, and leave the wifi range...when you return, will it connect again? Does the non-connection only happen after resetting the router?
Have you tried to use static IP for your phone instead?

This might be worth a shot if you could get NAT working, to eliminate the "obtaining IP address" from the DHCP... but if the IP is constantly refreshing and changing, I'm not sure it would do any good.
OK, I know some people are gonna think I'm absolutely nuts (and who knows, maybe I am ), but my wi-fi was working just fine last night. No issues, connection problems, no nothing. Then I went to bed.
When I woke up this morning, I turned on my Note but began having major wi-fi issues. Whenever I try to connect via wi-fi, I keep getting the message "Obtaining IP address...", yet my Note never obtains one. I've been fiddling around all day so I can get on the Net, but to no avail.
Does anyone have any idea what's going on here? I'm running stock ROM and made zero changes to my Note & router. Everything is exactly the same prior to when I went to bed last night.
Has anything similar happened to anyone else??
Thanks in advance, guys.
even i faced the same issue whole of yesterday...i thought it was some problem with the rom and changed back to the stock rom..but of no use...but today morning its working fine...seems wierd
its again stuck up in loop....connected..obtaing ip address..connecting

I had this issue, it would reboot TWlauncher, then work again.
Happens all the time. Use static IP as a temporary fix, it won't lose IP addresss again.
I have the same issue's, it seems to be an Android issue my previous Gnex had the same and i thought the wifi chip was broken or something.
After using the Note for 2 weeks on a random day i didnt have wifi and it had the same symptoms it could not find an ip adress. Now i simply use 3g at home.
I think it has something to do with either the wifi password encryption (wep, wpa, wpa2 etc) i have wep. Or the ip adress that is dynamic and not static.
Whats your wifi encryption?

Tried this already. I can connect, but now the wi-fi connection gets dropped for some unexplained reason every 5-10 mins or so, and I continually have to reconnect, which is extremely annoying. And that's not the only thing. Whenever I'm connected and using data, my laptop somehow loses its connection. And I know that my Note is the culprit because as soon as I disconnect it, my laptop immediately reconnects. Weird.
What makes this so frustrating is that I can't pinpoint the source of the problem. Literally everything on my phone and my laptop are exactly the same as before. I could understand if I was running a new ROM or installed a bunch of new apps/software on my devices, but that just isn't the case here.
I also tried resetting my router, but that's just a temporary fix (at least in my case). I've already had to reset it 3 times in the past 24 hours, and I don't look forward to the prospect of having to do this on a regular basis. Heck, I shouldn't have to!
Anyone know why Android (or the Note) does this? I still love my Note, but this wi-fi issue is fast becoming a nuisance.
Maybe your laptop and the Gnote are trying to obtain the same static IP from the router? (Check to see you ain't asking for the same IP!).
What does the router think is connected when you have both Gnote and laptop on?
Also, if that fails try the following.
1. Change Wifi channel
2. Remove the wpa+wpa2 option and just stick with wpa or wpa2 only.
3. Use a different subnet e.g 192.168.0.x to 192.168.1.x
4. Check the DHCP lease time is short enough (say 10 hrs).
5. Check you are allowing enough connections to be given DHCP IP's
Let me know how it works out.
I tried resetting my router but did not help, since my first post in this thread i flashed imilka's aosp v07 rom and now i'm back on wifi very weird.
My previous rom whas the chinese ics repack (no wifi at home) and the one before whas stock LA6 after a week use the wifi dropped out on that rom.
I still have a less secure wep encryption, but happy for now with the imilka rom.

a simple solution is to add your phones mac address to router whitelist. ..
I have same issue here. Whenever i turn-on my wifi, it scans public wifi even-though i have my own wifi with me. When im in public places and there's this public wifi, i cant connect. rather searching for another public wifi or and error message occur obtaining IP address.
my temporary solution is to disconnect from the connected address and reconnect the device again. Basically it helps
I swear, this wi-fi business is driving me nuts. Presently I can connect using a static IP, but even though I do connect and the icon shows a strong signal, I now have a new problem...I can't use the freakin internet!! I keep getting the message that I have 'No connection'.
Any solution to this? I have similar issue on my Note2 and Wifi works only on Stock Rom.

Not a router issue...
This is not a router issue, it is due to the wifi modem in you phone being messed up, have you tried flashing a mmodem fix for your phone? alternatively it could be due to file permissions.

First, you resurected a year old thread.
Second, you claim flashing a modem.img or baseband will fix wifi. Baseband AS NOTHING to do with wifi, the wifi firmware is (unless i'm mistaken) in /system/etc/wifi.
The problems op describes are hardware fault...
True.. Its drivers are in the kernel. Thus modem has nothing to do with it.
Hi guys,
My phone: Samsung Galaxy S3, GT-I9305, Android 4.1.2
I changed the ISP (Germany: To Unitymedia) and are now supposed to use a cable modem which as well serves as wifi router. My hardware is TC7200 (Technicolor).
After setting up everything, the wifi connection to Win 7 laptop and Apple iPhone/iPad is working fine (also LAN connection to laptop of course).
The S3 showed a funny behavior: It is possible to establish a wifi connection and it gets IP address assigned. Default gateway, DNS server looks all fine. However, this is only the wifi signal but not an internet connection. It is not possible to reach any website.
The strange thing: If the google site is cached (from a different connection and then switching back to this problematic one) I can run a google search and get results displayed. However, it is not possible to open any websites displayed as results here.
I tried several things based on suggestions in the net, like restarting the s§, using static IP address, changing wifi ports, disabling wifi encryption completely, restart the router, factory reset the modem/router. Finally I performed a factory data reset for the S3 but this as well, like all other things, did not help. The phone was never rooted until before yesterdays factory reset, because I wanted to use Titanium Backup which requires root rights.
Of course, in all other wifi networks so far, this S3 works absolutely fine!
I am not sure if this matters at all, but with the new ISP I got an IPv6 IP address while before I had IPv4.
To be honest, it might simply be a hardware problem which has to be fixed by Firmware upgrade by ISP. This problem is sort of known to them and when I called in they promised a firmware update in November. But anyway, it would be interesting to understand more about it and usually there is a solution for everything Nevertheless, I couldn't find a solution in any forum yet.
Any suggestions / ideas welcome.
Thanks!
EDIT:
Post already moved.
Reads like wrong settings more than hardware .
WiFi is kernel you can flash a kernel .
But i would reboot router and phone then set up wifi with no security first .
