[Q] Wifi disconnects data network after gingerbread update (i9000m) - Galaxy S I9000 Q&A, Help & Troubleshooting

Used Odin to update to gingerbread from froyo on my i9000m the other day. Theres no service here at home unless I put the phone on the bathroom windowsill, so I didn't notice until today when I went to work that I wasn't getting any data network connection. Could make and receive calls fine, wifi works, but no data, so no browsing or facebook or any apps that require it. I called bell and they came to the conclusion that I have to send the phone in for repairs. Thats a absolute last resort, so I tried another factory reset, this time from the recovery menu. The first time, during set up I enabled wifi, this time on a hunch I did not, and it worked. Also note that the first time, the network connected for a split second before disconnecting again. Anyways, I was getting 3g fine, then I tried wifi, and it disconnected again. Turn off wifi, data comes back. Whats up with this?

Did you set your APN? Go
Settings > Wireless and Network > Mobile Network > APN Names
Then hit menu and add a new APN if none are there. If one is there, it's named something like 'browser' (at least that's what mine is called on my Bell i9000m) and I'm wrong. But I had this problem, and this is how I solved it. You can find the APN settings for your network by google-ing "[Provider] APN Settings]", and if you're on bell you can find them here:
http://support.bell.ca/en-on/Mobili..._Nexus_One_for_the_Bell_Mobility_HSPA_network
It says Nexus One but it works for all phones on bell.

settings are exactly as depicted on the bell site, except the apn was called browser instead of bell. changed that, same thing. other suggestions?

Can you tell me the version of gingerbread you're on, where you got the files, any mods to the firmware like pre rooting?
Sent from my GT-I9000M using XDA App

2.3.3, downloaded from here, no mods.

Alright, so totally stock. What's the version code? It should be UGKG3. Have you tried forcing a kies update with a registry hack? Was it one PDA when you flashed it or 3 files?
Sent from my GT-I9000M using XDA App

Yes, its UGKG3. I flashed with the PDA, PHONE and CSC files. I dont really know what you are talking about with regards to forcing a kies update, if you could explain I'd try it out

This has always happened to me, on Eclair, on Froyo, and now on Gingerbread. Whenever my Wifi is active *and* connected to a network, the Data through HSPA is automatically disconnected.
I always thought it was a battery saving feature - if you have Wifi access, and presumably internet access, then you don't need internet through the cell network, right?
So if you're not getting internet access when your wifi is active and connected, then perhaps it's a problem with your wifi router not passing external internet to your phone?

The thing is nothing changed besides the firmware. wifi worked fine here in the house before and no problems connecting to the data network on the go with wifi enabled. I'm really running out of ideas here.

I guess I misunderstood you before. Are you saying you have no data access at all when wifi is enabled, whether or not you are connected to a wifi network? If that is true, something is definitely wrong. That doesn't happen to me with KG3 - just checked.
Have you tried reflashing the modem file? Maybe it got messed up in your flash before?
Sent from my GT-I9000M using XDA App

yes, no data regardless of wifi connected or not, as long as its enabled.
which is the modem file?

just an update, this seems to have mysteriously fixed itself.

internet access issues

so for apparently no reason today my internet stopped connecting. When I go to connect it says -
Dialed: wap.cingular
it says underneath it there is no modem at the above number.
ummm.... I didn't change anything in my setting but for some reason it won't connect to the 3G network. Any ideas here or do we know whats going on?
thanks for the help.

OK check this
START/SETTING/CONNECTIONS/MANAGE EXISTING CONNECTIONS/PROXY SETTINGS
and make sure that there is not a Check in the box next to :
THIS NETWORK USES A PROXY SERVER TO CONNECT TO THE INTERNET
This should do the trick I hope.
This always happens to me.
didnt work
no dice. its still giving me the same bounce back message that theres no modem at the above number. do i need to put a proxy server in the proxy server field? by the way this is a Tilt.
What program is trying to access the internet when this happens?
The same problem is occuring for me. I tried what Vol22002 suggested, but still can't connect. I was trying to access Internet Explorer.
Me Too - Atlanta
First thing this morning I tried to access the Internet with Opera and got the "Dialed: wap.cingular Cannot connect for unknown reason. ..." error. No recent changes to phone configs or software, worked fine after midnight last night. Power cycled and checked the usual stuff, still no data connection regardless of program.
Not Me Too Anymore - Atlanta
After not working from 0700 to 1050, I 'suddenly' have a working data connection. Go figure.
You'll probably find that this happens when your network is down. This happens very occasionally here and then I call my service provider to confirm this.

I would say that is the most common reason for the problem the OP is having.
the netowrk isn't down....
My dad's phone (not a tilt) is connecting to the 3G network completely fine. I can't access the internet through any program...internet explorer, opera, google maps, livesearch, the weather tab on my today screen...nothing. I'm at a loss right now.

still nothing...with or without the proxy on.
I've been having problems with my data connection and phone service dropping out for the last 2 weeks even though I have changed nothing on the phone. I see an x by data connection and exclamation point by phone. I'm using Dutty's 6.1 official release and radio 1.58.26.20. Usually I can get back service by turning on and off airport mode, and the problem is very sporadic. Usually only when I really need the phone to work! Sometimes just switching between GSM and Auto mode for 3G will provide a temporary fix. I just tried disabling the HSDPA, and we'll see if that helps in a more permanent way. I wonder if AT&T is kicking people off of its network that are using HSDPA before it is supposed to be available. I called AT&T about the issue (w/o mentioning the cooked ROMs or HSDPA and they say I should return the phone for warranty but I don't want the hassle of restoring the old ROM. Any ideas?
is everyone posting here with issues from ATL? I am and have had the same, figured its just a radio issue and have been too lazy to change radios...for those that aren't lazy, i'd try that...
nope, I'm in Oregon. I'm of the opinion that AT&T has changed something about how they run their phone and data networks (perhaps in preparation for the 2nd gen iphone and HSDPA) that is randomly kicking people off their network.

There goes the iPhone messing with Smartphones again. First changes what a Smartphone should be. NOW messing with the network. Hulk Mad!
Nope its not just AT&T im experiencing the same problem over in the UK. Now my proxy is disabled and I know I have all the correct settings but still the error message "unable to connect to the receiving modem." It seems to have no pattern for this happening con we get correlation on what ROM's & radios everyone are using to see if its that

App Blocking 3g Access

I currently have something on the phone not allowing 3g access. I can't seem to figure out what it is, but I believe I narrowed it down to an App. I did a wipe and clean rom install and 3g was working fine. I did a titanium backup restore of all apps with data and now 3g isn't working again. Anyone know of an easy way to pinpoint what is blocking my 3g? I tried ending all tasks in advanced task manager, but I'm guessing the phone would need a reboot to bring back 3g?
Have you check you settings-wireless & networks-mobile networks-use only 2g networks?
ya I tried using only 2g network, I even tried researching the network and it finds tmobile in the settings. I even went as far as getting a fresh sim card prior to wiping the phone. Somehow after an app/data restore from titanium back up, tmobile internet no longer works still. It's why I wiped in the first place.
1) Double check your APN settings in settings > networks > mobile networks
2) In dialer, dial *#*#4636#*#* > choose phone info > scroll down > verify that 'set preferred network type' reads WCDMA preferred.
3) Also in settings, make sure you didnt set 'use 2g only'. Same location as #2 above
Thanks for your help. I actually just did a nandrestore from an image I had that was a week old and internet came back, so it has to of been something I done within a weeks time. I just hope I don't end up hitting the app that stopped it, if I think it was one, because thats the only thing that makes sense to me.
I have your same problem could you be so kind as to attach the img you put so I try too? thanks

Then you will have his phone.
you mean....?
i Think i have a similar problem... I turn 3g on and after half an hour i cannot access the internet anymore... The sign in the notification area shows the "sent arrow" blinking but the receive arrow does nothing... I have apndroid to control my 3g usage... I unistalled it, did a reboot but again the problem persists... Do you have anything in mind???
I forgot to mention that the exact same thing happens with 2g network as well

When someone does a nandroid backup, it backs up all the data on the phone. All of it, if you restore it to your phone, you will be logged into google as him, you will have all his contacts, messages, settings etc. If one of you downloads something, it may download on both machines. The only way to fix it would be to wipe both of them.
i have the same problem. two days ago its working fine. i just turn on turn off the wifi and it just works again.
Can also try turning the airplane mode on/off. This problem occurs if you use APNdroid or similar, or toggle mobile connection on the Desire ROM.
tired of trying and try to wipe, reset, several rom, so I decided to send it to HTC in England ... and the problem is which has the bootloader unlock my ...

Tab on stable 3g but cannot use data

I have a Sprint galaxy tab I flashed to Visafone CDMA in Nigeria. I have been doing this for a while and everything works ok. Recently my tab stopped browsing, even though I have stable 3g data on it. I cannot use data on any apps on my tab, but strangely enough the hotspot works on other connected devices. I can use data on other devices connected via its hotspot. I can even use the usb dialup on the tab when I switch to modem mode, infact that is what I am using now to write this. I tried to activate daily data plan on my phone on the same network to see if it was a network issue. The phone is browsing well on the daily data plan, so it's not a network issue. Has anyone experienced this before? How can I solve this problem? Any help is appreciated. Thanks.
EDIT: I found the issue. Somehow the modem got corrupt, can't figure out how and when. I flashed VZW EF01 GBLeak with its EF01 modem and I'm back browsing on the tab again. I will try and get another copy of the Sprint EF17 modem and reflash the original Sprint GB ROM. If it fixes this problem then well and good, if not...

[Q] CM10 and no connection to internet

Hello all,
I flashed CM10.0 a few weeks ago and everything was working fine up until 2 days ago, now my I9000 won't connect to the internet at all. I was using Easy Battery Saver which cancels the data signal everytime the phone is idle, but this stopped turning the connection on. I uninstalled it hoping the phone would revert back to normal but can't get connected. I restored the app hoping it would pick up the settings again but still no joy.
I have wiped everything including user data and the caches, done a factory reset and reflashed the rom. The signal did return for about 30 minutes after the flash but the connection has since died again. I've tried switching on the roaming and national roaming, also no luck.
Does anyone have any idea what might be causing this or even how to fix it?
Thanks in advance

I am just guessing, but as from what I understand you uninstalled the application when you were not having the internet connection working. Right? The correct settings have possibly remained overwritten (some applications block the outgoing data traffic by changing the connection settings). Give APNDroid a try and if unsuccessful try going to your phone operator webpages and find the correct connection settings.
I am using CM10 with APNDroid which works fine. However sometimes I cannot connect to 3G as well. Switching the APNDroid on/off couple of times or rebooting solves the issue.

Thanks for the response mate. You guessed right, APNDroid hasn't fixed it and I haven't been able to find APN settings other than the one that is already in my phone. Might reverting to stock solve the issue? My contract is up at the end of the month so I could handle living with GB until then .
Hi again, reverting back will definitely not solve the issue. From what you had said I understand that the internet settings are somewhat messed up.
These settings are bound to your SIM card. By up/downgrading ROM these remain.
Could you check if your APN settings are correct (I assume you need to check with your provider).
Good luck and keep us informed.

Just found the APN settings online. Reset my APN and it looks to be working. I'll keep an eye on it just in case but I think either the ROM or the App messed up the user/password on the APN.
Hopefully it's all fixed. Thanks for all the help.
first try apn tweaker from market then if no luck what worked for me

Suddenly unable to connect to home wifi

So my wife's motox decided to stop connecting to my home wifi/cable modem. My phone (LG G2) as well as all laptops/tablets connect fine. My G2 can see about 8 nearby networks, the MotoX always sees my neighbors network and occasionally a 2nd or 3rd but that's about it. If my home network finally shows up I enter the password and it immediately switches to "Out of range" and shows as a Saved network. I enabled the hotspot on my phone and the MotoX still didn't show the hotspot. Here are the things I've tried so far:
- Forget network and readd it if/when it finally shows up as a visible network.
- Cleared cache from recovery
- Rebooted
- Toggling airplane mode
- Disable just data
- Power cycled cable modem. Also Hard reset it and set the network back up.
- Disable wifi optimization, notify when open network is available, as well as the always allow scanning.
- Switched from auto to 2.4 Ghz only.
- Switched between multiple channels on router.
The MotoX is the Canadian version, 4.4.2 stock, unrooted. Router is an awesome Hitron piece of crap but it's been working perfectly fine for months.
Short of doing a factory reset, does anyone have any ideas?
Thanks

You have already tried everything that I would suggest, short of a factory reset. If you do factory reset, please let us know if it resolves your issue. Since you are not rooted, I'm confused as to how this could happen :/
Good Luck
I am assuming you have already unchecked the "avoid poor connections" option too in the wifi settings.

Some routers can't handle certain number of conectinons, try rebooting your router
The router is built in with the cable modem which I've already rebooted as well as reset completely. Also with the phone only able to see a couple of networks at a time when there should be 8 - 10 visible at any time I think the phone is the problem. I just can't figure out what happened.

A few users have randomly had issues with WiFi, and their issues were only resolved by flashing the entire stock SBF as per the "Return to Stock" thread.
If a factory reset does not resolve your issue, you may consider SBFing back to stock. Since you will be flashing the stock rom (with matching CID), this is possible even with a locked bootloader.
Good Luck
I saw some posts about the SBF thing but wasn't sure if that applied to an unrooted / locked device or not. Thanks for the info.

An update for anyone looking for one. Her phone stated working fine yesterday on its own. It picked up and connected to our home network on its own and it can see all of the nearby networks like mine does.
Neither of us have done anything to it yet. Haven't touched the router or her phone since I first posted the problem.
Sorry I don't have an actual solution for you.

Ok so wifi decided to crap out again. This time I did a full wipe (internal storage included) and now wifi doesn't even turn on. It flips to ON for half a second then immediately back to off. Bluetooth does the same thing. I've called my provider (Rogers) and they're sending me another one.
Considering the wifi and bluetooth are on the same chip I guess the whole chip is toast or loose or something. Either way its well beyond a software fix.

You did a full wipe, but did you actually SBF back to stock? As I had commented previously, ONLY a full SBF back to stock can repair a corrupted filesystem. A "Full wipe" just erases cache and userdata.
SBFing actually REPLACES all the partitions. If you haven't tried, you can't say for certain that it is well beyond a software fix. It could have simply been a corrupt file...
Good Luck
If it was my phone I would have tried a SBF but considering it's my wife's she's a big more hesitant to let me and if they're sending us a new one, why bother?
