You must set up regular acces point.Sometimes that may be case sensitive.Set up that than reboot your phone.In case still not working call your mobile operator.

Or you can try manual set up your APN.

I've been having this issue for a few days now and I haven't been able to solve it myself. I've been using a GB rom for the past few months (this one and it's always been working fine. Still, I wanted to try ICS so I got myself to install CM9 on the device, and while I was at it, updated the baseband to 72. However, since then, I've been unable to connect to Wifi. I can see Wifi networks, but as soon as I try to connect it gets stuck on "Connecting". I tried flashing other ICS roms and restoring the baseband, nothing works. Yesterday I put the rom back that I've been using succesfully over the past months but still no difference.
When I scan for networks, they appear fine. Reception is good, but as soon as it tries to connect the icon changes to the icon for poor reception. It doesn't matter what network I pick. Other devices running Android have no problem connecting.
Does anyone have an idea what might cause this issue? Is there any way to get a logging of the Wifi to see what exactly goes wrong? Any troubleshooting steps I could take? Your help would be very much appreciated
edit: forgot to mention, with CM9 I used the CM9 kernel, with other roms I use Rage kernel
in exactly the same situation as above, except it was all working just fine until a couple of hours ago. now suddenly the router that's sitting right in front of me, giving full signals has turned into a "poor connection"!!!
i'm on CM9 with CM9 kernel and the recommended baseband
especially suspicious is the facebook application that just got updated when it was working fine a couple of hours or so back. hasn't worked since that update
Backup and try this https://www.dropbox.com/s/s587q1udg2ya2s1/Xperia Mini,LWW,Active_wifi_modules.zip flash in cmw and perform factory reset after that..
If it doesn't work then flash this stock ics ftf http://www.4shared.com/rar/du68FPM-/SK17i_41B0431__1249-7380ftf.html?refurl=d1url via flashtool...

Flashed the Wifi module, did a factory reset and it's connected! Thank you so much :laugh:
my problem solved as well. i didn't read rachit.rc96's reply so i solved it the hard way
was previously on baseband 72, flashed baseband 64 then 72 back again, no luck, went back to gingerbread, rooted then was able to connect to only one of my routers, the other one wasn't even showing up then flashed stock ics rooted that, now able to connect to both routers.
was that a problem with cm9 i wonder. or what?
Ok I need some help my buddy bought the S3 I9300 in India when he was there and it came unlocked and rooted, he asked me to throw a custom rom on it cause I'm pretty good with that stuff, so I got into recovery mode and did a nandroid and then wiped the cache did a system and wiped devalchick cache. Flashed the rom and it was successful and booted up everything worked fine but It would not connect to the AT&t network he cant make calls or send texts tried messing with his network setting and nothing would work, so I restored his phone back to original state and he still cant make calls or send texts anyone know what could be wrong check his IMIE number and everything is there and good everything works good just not the network....thanks
flash a different modem. also make sure the i9300 supports AT&T's frequencies
Where can I find the right modems it was running on at&t he wanted something smoother so I flashed the rom amd now it wont connect to any networks even when I reatored it back og rom

==========
happened to me twice upon updating my rom
what i did first is to checked my mobile netwrok then APN, restore the default APN and then reboot and if doesnt fixed it then change your modem
about the modem that is depend on what firmware or build you have, search xda and modems are lying around
Im using OMEGA ROM V44.1 and it is working perfectly on my S3
gudluck and hope this will help you
I searched other threads but found no solution.
I flashed from RRemix to Cyanogenmod and lost my Mobile Data, then went back to my Nandoid backup and everything was fine. Then tried a newer version of the RR Kit Kat and lost Mobile Data again. I went to the backup of my older RR Kit Kat and it works fine. Just curious what the issue is, I would like to be able to switch or update ROMS.
This is for a GT-i9300 btw.
Thanks!

After installation of new ROM take out your SIM card..Boot your phone>power off> Insert Sim card boot again.
I believe the APN settings is not proper. If still not worked then you have to call your SP and ask to send APN settings to your phone. It should happen automatically but may be once your phone register to SP, then SP unable to understand the phone model and not sending the settings.
Try to enable plain mode and disable
You can also Google your apn settings and set them manually lots of roms don't set them and you need to do it manually.
Hi everyone! I installed a custom rom (PureX Z2 Premium v1.0 23.4.A.1.264 5.1.1) yesterday and everything seemed to be working great. But when i left home today and i lost my wifi connection, i noticed that the phone didn't establish any 3g/4g connection. So i looked around in the settings and realized that i couldn't activate mobile networks when i had wifi enabled, but when i disable wifi, the mobile network works like a charm.
I installed the rom from an unrooted, stock rom device, and it wasn't any problem to have both wifi and mobile networks activated pre custom rom installation. So that mobile network took over when i lost wifi connection. I thought this was standard behaviour for android?
Anyway, im wondering: Could this be a problem (or even a "feature") in the custom rom? Anyone else had this problem? Is there a standard android option in the settings for this? If not, is there any app/xposed mod that could fix this for me?
just re install the rom, I had the same problem with PureX Z2 v11 the first time, after that so far no problem.
I hope you serve, Greetings
Thanks for the reply!
Should i redo the entire process including wipe data / factory reset, or can i just re-flash the rom without losing any data?

reinstall wipes just cache and dalvik, if I remember correctly... only lose things of system you've changed
Okay, so I've been trying lots of different roms on and off, all of them seem to break mobile data.
I'm on Mobile Vikings in Belgium, on the Base network.
Anyone else experiencing this?
As it occurs with any rom, I'm pretty sure it's not rom specific (also obviously most users aren't facing this issue).
Also, reverting to a backup of OxygenOS breaks mobile data as well.
Really frustrating as this means I need to do a full wipe, re-install stock oxygen and set up my phone from scratch...
On most roms APN settings are automatically correct (sometimes I need to select the right carier, sometimes I need to make a new entry when my carier is missing). Anyways, after a setup it always all looks like it should just work.
Regardless, when switching on mobile data, no 3G or LTE or even edge icons appear in the status bar and the phone remains offline.
I really hope I'm being stupid and there's some solution. As of now I'm forced to stick with OOS Lollipop if I want mobile data (which is a must have feature for me, as I'm sure it is for most).
Actually just finding out I'm not the only person dealing with this frustration would already be comforting to be honest
Backup efs from stock rom. Restore it after you flash a custom rom. And also reset apn settings after the phone boots up.

Thanks for the fast reply! I will try this solution after work & keep you posted!
Is restoring EFS often a necesity? I've been flashing since my zte Blade days, never needed to backup EFS before... Maybe just lucky so far?
I have the same problem. I'm on Mobile Vikings too.
zTweaked's tip worked like a charm! Thanks again man!
Posting this on Exodus ROM on LTE btw
Highly recommend following his advice to all Mobile Vikings (or anyone else facing this issue)!

Welcome, mate. I often face this issue. Sometimes rebooting my phone gives me problems like this. Restoring EFS is the easiest way to fix.
