This is happening to me too; nice to know I'm not the only one although it seems to be a rare problem.
OTA update which seemed to run without a hitch, stock recovery, coming from rooted but otherwise stock honeycomb. I have voodoo OTA root keeper, which did it's job.
I'm fairly conservative with the tab, I've not changed any of the default settings since the OTA, I let all my apps redownload after the update and their data was still there; I have TiBU but didn't need to use it, definitely haven't restored any system data or aps.
My tab sees the sim card, I can send texts and get replies, it knows what network it's on, I get occasional notifications but can't actually connect to anything (have tried search, the browser, FB app, gmail app, news app, all time out).
The simm card works fine in my phone, the simm card from my phone which gives me mobile data on my phone doesn't on the tab.
Settings says there's no ip address available - I never checked before the update, don't know if this is normal.
I've not bothered much with customising the tab since I mostly use it for work, can anyone suggest where I might start trying to fix this?
eta:
I checked a number of threads about mobile data and honeycomb - to get to mobile network settings you go
settings > more > mobile network
I wasn't in flight mode, packet data was selected, network mode was on auto.
The fix turned out to be changing the apn - there are 6 offered, I worked my way down the list (I could have phoned and asked, but that usually means being on hold for 30 minutes first), most of them had no network at all, the default one had a network connection but no mobile data, one works properly
(my tab is on Optus, the correct apn turned out to be optus preconnect)

[Q] No data connection after R2BA026 + market fix?

I ran the one click exploid .apk root updater/market fix/root today and everything is working properly EXCEPT my data connection. I've looked through settings and stuff to see if I had to manually connect to the network or something and had no luck.
My phone is an X10a and I'm with Rogers. I haven't called the carrier to see if there's anything they can do, I figured I'd check here first.
You tried the auto internet sectionn in Wireless settings >> Mobile Network settings?

[Q] No Data Connection in 2.1

Yesterday, I successfully updated to android 2.1. I have confirmed that the APN information is correct and that there is sufficient network coverage. I have activated data in the settings - yet I cannot seem to get a data connection. Unless I activate WIFI, neither facebook nor mail will update, and I also cannot open websites in several browsers (opera, fennec, standard browser, dolphin).
I also don't get an icon for 3g or hsdpa connection.
Anyone having the same problem? Or even better... a solution?
Best,
-Mike

I would say it's your carriers networks are down. I had a similar problem but the 3G symbol was there and it just would download anything. I then disabled juice defender and it works perfectly.
If you are running the nordic kit this seems to be a fairly common problem. One of the guys over at phandroid fixed this by going to the SIM Toolkit and downloading settings, but I did not have this option. I was able to get it working temporarily by fiddling with the APN settings, but then like you it just failed to work any more.
I have flashed back to 1.6 and am now going to update with generic uk firmware.
So - I tried the Sony Ericsson option in the settings (topmost menu entry) to automatically download settings, I tried setting them manually, I tried auto-configuring via the apn-options... nothing worked...
then, suddenly, without having changed anything - I get a 3G signal. Seems to have sorted itself out for whatever reason. Will update in case anything changes.

[Q] No Data Connection After Flashing to Stock Via Odin

Hey, I got a softbrick on my vibrant, reflashed back to stock and everything is working except I get no data connection. No 2g/no 3g, no Data icon at all. Even if I am on wifi I am also unable to download anything from the market place however my datasync / push with e-mail also works.
Any ideas?
Thanks
figured out my APN was empty... all good.
same issue, i don't know how to fix it. Mobile Network state says disconnected and connecting but never connects...
Might help to say I'm using a Galaxy S Continuum
and the only reason I'm posting here is because this is the only topic similar to my issues.

I couldnt figure it out either, so just used Wifi to get myself going...
Turns out 2.1 doesn't support two factor authentication with Google accounts, (at least I couldnt get it to work) so you may need to turn that off too to get going.

[Q] internet gone AWOL

This is a weird one. For a month I have been using the Leedroid rom with Honeycomb. I have the /htc /flyer 32gb with 3g (UK). In the last few days I have lost my internet connection on both wIFI and on 3g. I did get it back for a few hours today and now I can't connect again!
Having a tablet with without connectivity is a bit like having a fancy brick :-(
I have tried removing the Sim card and re-inserting it and trying a different wifi router.
Anyone else had issues like this?
i assume you haven't made any changes/modifications/installations recently that may have messed with it?
for your 3G connectivity, put your sim card in your phone to determine whether the issue lies with the sim card or the Flyer...also check your APN settings
same with wifi - can you connect your phone to your router's wifi?
my guess is that you installed an app that's messed with your settings
Problem solved (sort of)
Thanks for the reply
You may have been right that an app messed up my settings. I know the APN settings were correct as I could connect from my Nokia phone using them and the SIM card. I could also use two other definitely internet connected routers.
In the end I did a factory reset using CWM. After a few scary moments after the re-boot it was working again. Evidenced by the fact that after reboot the tablet tried to download my previously installed apps again!
I have had to re-do some settings and the Flyer seems to be runnng a lot more smoothly than before. Still no idea what caused my problems but will definitely be checking after I install apps in future that my web connection stays up just in case! Update, it seems my g and ADSL wifi are not getting along together - had no probs before though....mmmm....

you can stop that from happening...that's a "feature"...lol...either untick "back up my settings" under >settings/privacy; or don't add a google account after a new flash until you have reinstalled apps from a backup

some people have had success changing the wifi channel on the router to something higher than 11 (so i've heard, i've never had to do it myself)...you may also want to try setting static IPs for any other wifi devices to avoid conflicts
either way, it is far more likely that the issue would be settings other than ROM related, else everyone else would be having the same issues
you could also try something like this

[Q] Wifi connects, no internet after update to ICS

Hi guys,
So my Evo 3D updated to ICS last night, internet worked before and after update. The phones internet just stopped working, it connects to the wifi router, tries to sync, i try open anything that requires internet and no internet. The symptoms are as if i entered a setting wrong, but trust me i have been trying this for hours to FORGET network then re-add it. I rebooted the router, i have tried connecting to another router, it connects but no internet (i am using static, its my work connection). I can ping the phone.
What are your suggestions? I have cleared all cache, took battery out. When i use Mobile Network everything then works. This is very frustrating as Wifi should be a simple thing for Android. PLEEEEEASSSEEE get this working
I have the same problem... today i updated my evo to android ICS and connect to wifi, wifi is connected, but not internet
Try to do factory reset.

I tried but it did not help..
Simple, ##786#. Enter your MSL code. Click yes. Phone will format itself (no, not your SD card). It will clear any NV (Non-Volatile) memory. And it will have blanked out IDs for Username and MEID and whatnot. This is not just a factory reset or a /data wipe. After it finally boots up, it will give the 'Hands-Free Activation', followed by 1x connection, followed by 3G.
I am assuming that the ICS update was an OTA, which means that I am unaware of the official Sprint update. I'll read the General forums see if that's what it is. Nonetheless, if this is a custom ROM, be aware that some custom ROMs will NOT properly activate after an RTN reset. In the case that it IS the case; and you don't have any connectivity, even phone services, simply flash a Stock rooted ROM. Edit: I see you did mean the official OTA, so ignore this paragraph as it only applies to a few custom Sense ROMs, and all AOSP ROMs which can accept ##RTN#.
In the case that your phone is not rooted / S-Off, ignore the entirety of the 2nd paragraph.
Hmm, maybe ignore all this, seeing as how I misread it was your WiFi erroring. I do not see how an RTN will fix that. One of the .ko files probably needs replacing.

Same problem here. I connect to home wifi with static IP address and I can access everything in LAN but internet does not work. Yesterday I was connected on DHCP wifi at work and it worked without problem and when I came home, at my surprise, my static home network also worked (without changing anything). But today I was not connected to work wifi and when I came home I got same problem again

There are also others with same problem: http://forums.androidcentral.com/htc-evo-3d/183734-no-internet-access-through-wifi-after-evo3d-upgrade-ics.htm
DNLA auto-IP make sure thats not checked It shows connected when this option is checked but internet does not work. Make sure DNLA auto IP is not checked. This is under advanced options.
Hi!
I had the same problem yesterday as I installed the TeamGenesis 1.0 ICS ROM.
I restored all my data (also the system settings) and there was the problem. The "APN" has to be reset in the settings to default and than it worked for me again.

try configuring your mobile network access point.

OTA upgrade sometimes cause problem, please search a RUU ICS Stock, extract to get rom.zip, rename it and flash it via Fastboot.
