I'm having a problem since I flashed the sensation rom (by crysis21) on my SGS2 yesterday.
My internet connection (mobile network) doesn't work anymore
I checked the APN settings and already resetted them and enterd my APN settings again. But it still doesn't work. I also restarted the phone multiple times.
Does anybody know where the problem is?
Installation steps were:
*copying the rom to sd
*CF-rooting the kernel via Odin
*booted up in CWM recovery and chose "install from zip file" and installed the rom (without any wipes)
Before I had the default samsung factory rom on it.
Have I made a mistake?

Have you checked the APN settings are the good ones? One thing is to have ones enabled and other totally different is to have ones that actually work.
Also when you go from Stock to Custom ROM you should do a full wipe!
Go to CWM and format /system, /data, /cache and reinstall the ROM.

thanks, I'll check this out as soon as I get home.
I refrain a little from doing a full wipe because I don't want to get all my apps deleted (and I'm a little too lazy to perform a backup). Would mybe a new modem solve this problem?
And of course I checked the APN settings. I deleted the existant APN setting and added a new one so the settings can't be the problem.
I also checked some entries in Settings/Phone Info/Status.
It says here (translated from german):
Mobile Network Type: HSDPA
Service State: Function (or working rather)
Mobile Network Status: Disconnected (but sometimes it says also connecting here, though it never really gets conencted)

Even though I wiped everything, the data connection still doesn't work.
I did
"Wipe data/factory reset"
"Wipe cache partition"
"Wipe Dalvik cache"
and after that I installed the Sensation rom zip file again.
The data connection still doesn't work :'( (I added the APN after install, of course - the settings are 100% correct).
I also installed another rom (infected rom) but there's still no data connection.
Am I missing something? I'm getting really desperate over here.

You could try flashing another Stock ROM via Odin and see if in stock works or not, then try a Custom ROM.
Sometimes the phone takes a while once you flash a new ROM till it establishes a decent 3G connection. Having "Data enabled", how much did you wait for the phone to establish a connection?

I thought so too... Well, at work I waited some hours for the data connection being established but nothing happened.
This is crazy. I even restored my system with CWM and it still ain't working.
As soon as my GF comes home I'll replace the sim cards. Maybe the problems at the providers side...
after that, I'll try a stock rom (via odin).
thanks for your tip

I have the same problem and I'm on check rom.
i'm having the exact same problem, but with multiple roms and not just one. i tried omega and delv. both of these are giving me no data connection (only at the beginning) but once i restart there's no data connection.
did you manage to figure out what went wrong? I've resulted in my original rom that i had by restoring it using cwm.
dear sir,
my device is micromax canvas a1 aq4501. when I recovering a custom rom like cm13 my device Internet data not connected. I fully checked setting like mobile data, apn, but it still not working.
now I want my device situable custom rom. please give me the right information.

I flashed the ICS Euphoria ROM for Samsung Vibrant, but now I cannot connect to wifi and my phone doesn't pick up my network (neither does it search for it). I have not flashed the kernel yet because I do not know what I need to wipe in CWM Recovery before installing it.
So how do I flash the kernel, and how do I get my wifi and mobile network working again?
Any help would be greatly appreciated.
Thanks.
EDIT: i flashed the kernel after wiping dalvik cache, but its still not picking up my network or wifi
EDIT2: WIFI works now (I was dumb) but still no carrier signal. It just says No Service. Please help.
EDIT3: turned out it was the ICS Euphoria ROM that was at fault; i have Passion now and it works fine.
RESOLVED BY MYSELF. THANKS FOR THE HELP
Hi,
I've updated the phone to the newer firmware from KIES, and the phone was connected to the WIFI network but signal connection keeps switching on and off, is there anyway to fix this issue so I can have a stable connection?
Have test with my iPhone and Ipad, both connectect to the same WIFI and only my samsung S3 having this problem.
PS: WIFI power saver mode is already <<off >>, keep Wifi on during Sleep mode is set to <<always>>, Network notification is <<un-tick>>
This is my current ROM (Rooted)
AP: I9300BUBLG3
CP: I9300BULG2
CSC: I9300VFGBLG3
settting > wireless & network > more > mobile network > automatic connections > sprint connection optimizer.. unchecked?
This is the international version is Samsung S3, I can't find such settings.
Sent from my GT-I9300 using xda app-developers app
I had the same issue when I reverted to stock. I thought it was this and that but really, all I did was
Backed up everything
Well mine was rooted and stuff so I triangled away the flash counter, probally dont need that if your on stock anyways
I wiped everything from the phones settings, back and restore, reset
I then booted up in recovery, doesnt matter if you are cwm or stock recovery, wipe again plus cache
Now I loaded up Odin and flash the original stock rom for my phone, I waited till it was complete, I then updated it through settings till I got to the latest update and then started reinstalling my apps from google play store or whenever else I had apps. So far all is well and no wifi issues.
Other advise would be instead of all the above, wait for another update or flash a new modem. That also worked for me when I was running another countries stock rom, Bad wifi, so I flashed my countries modem and it was fine! so good luck!
go to dialler
*#0011# will take you into Service Mode
click on menu
click on wifi
you will see a button that says "on" click on it
it will say off this stops the wifif connect/dis-connect problem.
If you shut down your phone you have to reset it to off.

This was the latest stock rom from KIES update (also rooted). But thanks for the reply, I'll try to flash different ROM and see what will happen.

I've got the exact same problem. Do you have a BT Home Hub 3 by any chance?
I've just rooted mine so am going to try and flash a new modem and see if this fixes the issue

Sorry I don't have BT Home HUB 3, my connection is very simple, just connecting the S3 to a DrayTek Vigor2710Vn Router via Wifi. Please let me know the result after you flash with a new modem. If is working, please provide the link and file name where you got your file so I can flash it too.
Thanks!!!!
***By the way, what ROM version are you using at the moment? Please provide your AP, CP and CSC details if is different to my S3. ***
Repeat Modem has nothing to do with WiFi.

I had the exact same issue, but ONLY after rooting the device (which I did just a day or two after I got it). I tried every possible fix, flashed new roms 3 or 4 times, wiped data and everything else in recovery, but no luck.
However, my final solution was to simply follow a guide to unroot the device, which I did today - and it did indeed work, I guess this issue is mainly happening to rooted phones, for unknown reason. Until I know this is fixed with an update (maybe in 4.1 JB), I won't be rooting this device again.
Link to guide on how to unroot
Are there actually people who can't fix it like me?
Also done everything I possible could but never got wifi working again.
Returned it to Samsung. I unrooted it and flashed the firmware again with KIES.
The day after there was also an official update for the BENELUX I guess. Also updated this with KIES.
So is it still possible they see that the modem was changed?

Yeah as the guy above me said, you always have to reset the flash counter before unrooting (as this requires superuser access).
If you don't do this, it's easy to see the phone has been modified in either download mode or by checking status in settings.
After successfully unrooting you'll also have to re-enter CWM recovery and wipe data+cache.
After doing this you'll see the device being "normal" and it should show "stock" in download mode.

Forgot to mention it but I did this yes.
I also think KIES would not update when this is not a zero.
Stock ROM, only rooted. It was working for a bit. Didn't change settings in the router. Within 8' of the router
Any reasons or solutions to this?
help possible no wifi connection!
got me the Acw-i Sure rom 7.0.0 on my samsung gt-s5839i made and now I can no longer connect via wifi because ... can someone tell me what I need ...
thank you before this
AW: Wi-Fi connection problem
Try in cwm advanced -> Fix Permissions and Wipe Dalvik-Cache.Try cleaning the RAM too. If it still doesn't work do a backup with titanium backup and then a wipe data. If it still doesn't work, flash the newest firmware (and reflash the custom rom).
¿U mad bro¿
Hey Guys
Since many apps don't support GB I was forced to do update.
After flashing with original JB 4.1.2 everything seems to be ok, but there is no way to turn wifi on.
WIFI icon on bar is half-highlighted, tapping on it gets no results......Wifi tethering not working also
Cache and Full Wipe was done, there was suggestion to flash with "siyah kernel" - also not working.
It seems that problem is related to fault ROM file because on ICS and GB wifi works fine......
Any tips? suggestions?
i9100 without wifi is useless :crying:

Did you flash the correct JB update? Maybe try a different STOCK JB rom from a different region.
Or directly try to install a custom ROM, for example CyanogenMod.
