[Q] Strang network/signal problem in Galaxy S2 I9100G - Galaxy S II Q&A, Help & Troubleshooting

Hi Friends,
My Samsung Galaxy S2 (I9100G) has a strange network issue. My phone suddenly becomes unreachable and network does not reconnect automatically but it shows full signal bars on the display. I have to restart the phone then only it works. It happens many time in a day.
My phone has offical 2.3.6 without any customization done on it. I installed ICS also but facing same issue.
Model: I9100G
Android Version: 2.3.6
Baseband version: I9100GDDKI1
Kernel version: 2.6.35.7 [email protected] #2
Build Number: GINGERBREAD.XWKJ2
Please let me know fix for this issue.
Thanks

Try changing modem version.

I'm having the exact same issue. How do you change the modem version?

By flashing modem file as phone in Odin or by CWM.

Try GetRIL from Google Play, this should fix your problems.
Baseband and Modem version do not match, thats why your having this problem.

I am experiencing the same issue, however, according to GetRIL both my baseband and modem are matching. What shall I do next?

Network issues

First of all HI to everyone. This is my first post on XDA so if I messed something up dont be too harsh..
The question is: My S2 every once in a while losses network. Sometimes it happens during calls, or sending sms, browseing... If I remember correctly it didnt happen while I was on gingerbread. Any ideas? If yes please point me to the right thread.

I've read numerous posts and topics about this problem but havent found a fix. Hopefully someone will point me in the right direction... Thanks!
If it was me Id try a few combos to see if its software or hardware.
Gb with getril/without getril
Ics with getril/without getril
Personally I dont like getril.....
It's because of siyah kernel. Use newer version of siyah, this one does not dropped calls.

OK, which one should I get than??
DorimNx 5.92 is perfect.
Siyah latest 5.0.1 is good, but high battery usage.
Latest dorimanx v7.xx had low 3d scores....
I suggest dorimanx 5.92 plus xwlq3 rom, not an single dropped calls.

Updateing siyah did the trick. No sudden call drops or lost of network since I updated.

[Q] Wifi unable to turn on

hi, i've a sgs2 GT-I9100 which is now rooted;
Model number: GT-I9100
Android version: 4.04
Baseband version: I9100XXLPS
Kernel version: 3.0.32-CM-ge9cef6c [email protected]#1
CyanogenMod version : 9.1.0-galaxys2
After the official update by samsung to ICS, i can't seems to turn on my wifi, it just keeps turning off and reboot by itself. Hence, i root my phone to see if i can solve the problem from this direction. i've tried factory resetting but my wifi mac address just keeps showing "unavailable", with other phone stats like IMEI, ip address and serial number showing.
from rootbrowser, i can find my mac address under efs/wifi/.mac.info however it just don't get shown on the stats and i can't switch on my wifi or tethering. 3g is working fine.
need some help here on how to get it to work. thanks!

Hello! I have the same problem as you! I can't turn on my wifi on my SGS2 too. I have tried flashing other roms/kernel but still not working.I hope it is not a hardware issue.
Did you try to wipe cache at recovery mode?
I know some users with that problem , sometimes are by hardware issues....
Is strange issue.

The fix is simple, all you got to do is flash siyah kernel using odin. If it doesn't work, let me know

[Q] Data connection 'asleep'

Hi, recently I just flashed liquidsmooth rc2 4.2.2 rom. The data network seems to be always 'asleep', I do not receives notifications for whatsapp and facebook. Unless, I surf the net using browser or stream some youtube videos. I saw many posts about flashing a radio after a custom rom, so do I need to flash a radio? (there is no fm radio app after i flashed the rom and gapps)
Model: Samsung Galaxy SIII GT-I9300
Custom Rom: LiquidSmooth v2.1-RC2
Android version: 4.2.2

Radio in this case means modem (baseband)
You have a baseband but it might be incompatible, ......it's the baseband you are showing the one you had before the flash?
Also check your apn settings, you might need to get them from your carrier

The baseband is after the flash.
I checked the apn settings, nothing seems wrong.

What baseband did you have before? Might be worth reflashing modem+ ril
