No Internet on custom roms 19300

No Internet, it was working on Stock XXDLH7 Official, 4.0.4 19300
I updated to 4.1.1 with No wipe and had no data, apart from service provider (GiffGaff)
I also did a clean install and still no Internet apart from service provider, this has happen on 3 custom roms so far
the wi-fi connects but wont signin or loads web pages and times out and keeps popping up that it is connected.
I have also tried the official leaked version 4.1.1 but still the same
would I be able to install stock 4.0.4 kernel (unmod) onto 4.1.1
Any ideas ??? or any ideas around this issue
Many Thanks
Baseband : 19300XXDLH7
Kernel : 3.0.15-928452
Build : IMM76D.19300XXBLG8

Yes tried the official leaked version and also 3 custom roms but still have the same issue ( Wi-Fi is connected but fails to load any thing, but if I switch wi-fi off and use service provider data it works fine.
Its your modem try NELE4 from the modem threads .
O2 seems to have a problem with current JB test modems .
Its in the modem thread or Index sticky .
The fix is not for network so don't bother .

Slow speed

I have 2 Samsung S3 - one unmodified and one flashed with RR_JB_V3.0.6.1_AOKP_4.1.1_I9300 -STABLE.zip (Modem XBLFB).
There is a huge difference in network speed between them.
Running from the same spot on my desk, having the same operator with the same subscription I got following with app Speedtest.net:
RR : 1.84 Mbits
S3: 6.42 Mbits
What is wrong ?

Try flashing stock via odin again and then RR again. Buy there's really no guarantee that anything modified will run as well as stock.

Don't understand why it should make any difference ... after re-flashing stock & RR ... I will be at the same position as now
I believe it is related to Modem ...

The network settings are the same for both S3

Whatever modem works is the right modem suggest use the same modem as the one that works well .

OK - the baseband version for the unmodified S3 is I9300XXLH1.
So I had to find the modem XXLH1 and install it with CWM Recovery.
Where can I find XXLH1 ?

If you check the CyanogenMod thread you'll see that a lot of people had issues with slow download speeds. It was fixed by first flashing the stock G8 rom and after that CM10/AOSP/AOKP. Do try by changing the modem first though.

You don't necesarily need to flash a stock, ROM, just re-flash the baseband, using Odin..
I don't have a link, at the moment, but there is always Google

flash a different modem

[Q] Please help. Dont know what modem to use?

Hello,
I own a samsung galaxy s3 gt i9300. I rooted my phone and stuck to stock modem for a while. I then flashed paranoid android 3.15 on it which still used the stock modem. Then i flashed omega rom on it which changed the modem I guess and now I cannot connect to my local number. My IMEI number is there so my EFS is secure ( I have backups of it too). I tried flashing XXELLA modem first since that came stock with the phone when it came. I tried multiple other modems like XXEMB6 and XXEMC2. But it wont connect to my mobile number. I live in Pakistan and bought it factory unlocked from samsung.
Can someone please guide me as to which modem to flash? This is a modem problem right? Because that means I can never flash custom software with different modems. Or is it a CSC problem?
This is the thread i used for flashing/downloading modems! http://forum.xda-developers.com/showthread.php?t=2076857
First attachment is the stock configuration the phone came with
Second is the new ROM i put in which is omega rom.
I even restored my nandroid backup of the stock working official samsung ROM. But still no connectivity. Someone help please!?

Multiple modems suggests you have not entered the correct network APN settings for your network .
Or Sim is faulty .

Called up the network. Everything is fine on their end. And I was told APN settings is just for Mobile Internet (GPRS/Edge yeah I know Pak doesnt have 3G yet lol). It happened right after flashing the new modem. Any other solutions?

I checked the IMEI. Still there.
Sim works properly on another phone.
CSC settings I tried of many regions (through CSC changer app) from EUR to PAK to even MID (middle east)
As for modem, I flashed stock firmware from sammobile for Pakistan, the latest one, and it still refuses to connect. APN is fine according to network.
P.S. I dont know if this holds importance or not, but I did experience SDS. And my local repair shop (owing to the abysmal samsung warranty policy in pakistan) repaired it. But they did not change the motherboard. They changed the 'chipset' only and upgraded it to 4.1.2 firmware with the sds patch fix. Might be a stupid question, but could it be that the new chip hardware they put in is from a different region, so they had to flash a different regions firmware, and the answer to all my problems could be flashing the one they flashed after i ask them!?
Thank you!
anyone?
Read the rules, do not bump before 24 hours has passed. I will report it next time.

IMEI as under the battery .
A guess is that service centre broke something .
