Flashed Omega rom and now WIFI range is extremely poor - Galaxy S III Q&A, Help & Troubleshooting

Hi all,
Pebble Blue i9300 SGS3 unlocked
Was on Android Revolution HD 14, full wipe flashed Omega 33.2 which is when I notice the issue where I would only be able to connect to WIFI within 3m distance from router (used to work from outside house and across the road now only in the same room). I can see my network at full strength in other rooms of the house but I receive authentication error/incorrect password despite it being correct.
I then decided to rever to stock rom, I unrooted and did triangle away and flashed the rom my phone came with, problem still persisted.
Then flashed back to Omega 33.2 with full wipe and problem persisted.
Did a series of full wipe -> flash -> factory reset in OS -> full wipe -> flash -> factory reset, after which the problem still persisted.
Flashed Omega 33.3 today over top of Omega 33.2 with full wipe and format /system from CWM, problem still persists now.
Any ideas on how I can remedy this?
Thanks
Van

this might not be related but give it a try
-Try changing your WiFi channel maybe to 6? or 7

Try a different kernel try a different rom .

Hi, thanks for the suggestions.
I have tried already different WiFi channels and have tried 4 or so different ROMs and the siyah kernel. Have tried aosp and stock firmwares along with the Sammy based jellybean ROMs. Have tried cm9.1, stock 4.04, stock 4.1.1, leaked 4.1.2 stock, omega v33.2 and 33.3.
WiFi was perfect before my first flash of omega v33.2, immediately after the flash it was extremely poor and hasn't changed through all the ROMs I've tried since then.
Wondering if it could be somewhat coincidental and my WiFi module if faulty. I could reflash to stock and send for warranty but would only like to as my last option.
Thanks
Van

Not sure if it's the case with Omega ROM, but I had a similar issue with an AOSP-based ROM. Solution was simple: flash back to stock ICS ROM, connect to wifi, then flash back to JB ROM. NO problem after that. might be worth a try before sendning it back for warranty.

Thanks for suggestion, had tried that when the problem first appeared and it hadn't worked. Just went back and did it again, wasn't able to connect to WIFI on stock rom I9300XXALE8_I9300NZCALE5_NZC, did factory reset from within rom, still unable to connect. Rebooted to stock recovery and wiped data/factory reset, wipe cache and rebooted straight to downlaod mode, flashed stock ics 4.0.4 I9300XXALE8_I9300NZCALE5_NZC again which is what came on my phone. Still no go with WIFI despite having 4 of 5 bars of signal. I get the connecting symbol which goes for a while then changes to scanning and back to connecting again, meanwhile under the wifi network in question it just remains "saved, secured".
Just performing triangle away/re-flash stock once more to preapre to be returned for warranty.
Any other suggestions?
Thanks

[Q] Phone stuck on Galaxy logo !!

I recently installed WanamLite V7.7 XXLP6 Android 4.0.3 Final LP6 on my phone, but the signal was awful, so i tried to install [KERNEL] SpeedMod SGS2 [K2-20 CWM5 CIFS ROOT], hoping that it would fix my problems with the signal.
After that, the phone is permanetly stuck on the Samsung logo and won't go any further. I tried to re-flash the ROM but the problem is still there.
After that I've tried to fix the problem by following instructions on this thread: http://forum.xda-developers.com/showthread.php?t=1108499, but still nothing.
Can someone please help me to fix this problem?
Thanks for your time
I think that you need to do a restore or to flash a gingerbread rom before the ics one... Speedmod is not for ics roms...
Sent from my Galaxy S II powered by CheckROM
You said you followed pulsar's "boot loop" thread... so does that mean you cleared cache, wiped data, factory reset, all that?
Also, a future FYI. Kernels will never address your problems with phone signal. Flashing modems will, but kernels, never.
However, they might affect wi-fi signal, as some kernels have wi-fi drivers included.
Thanks for your responses. I';ve managed to fix my problem by flashing a gingerbread rom. After that i had major signal issues. I've flashed the main modem for my S2 (ki4) but i'm still facing the same issues. Any ideas how to fix the signal problem?
....................................
Clean Slate for those that balls up the firmware .Or need to return to service or decide if its hardware/firmware problem .
Or have just not a clue what they installed .
Backup data first if phone is working .
Boot CWM recovery
Mounts and Storage
Format cache data system sd card .
Remove battery
Boot to download mode
Open Odin
Install correct stock firmware .
jje
Try different modems until you find one that works well for you. That's what I and many other people on here have done. This is one thread with CW flashable modems (there are others, search), there are other threads on here (search) with Odin flashable modems if you prefer to use that.
i tried many... right now i'm using XLP6 which shows -93dBm but still when i'm on the phone, 90% the connection is lost and the phone hangs up
I've found that how well a modem works for you depends on where you live and service provider. For me, in Germany on T-mobile I've found XXKI3 to have the best results (with CM7)
I would be trying the modem that came with the phone .
jje
im also running wanamlite 7.7 but with the LP6 kernel...and indeed the kernel has nothing to do with signal levels
i did change the modem to XXKPA and the battery, signal has improved a lot so im sticking with it, my phone originally came with KK1 which kinda sucked even with stock rom
so follow the link they gave you and try the modem untill you find one that suits your needs
by the way, before flashing stuff you should read what is made for what rom so you can avoid bricks/bootloops

[Q] No CDMA Service on Custom Roms

Hey guys, I'm not new to rooting or flashing ROM's but I've encountered some issues. Basically, I was on an early JB Rom and everything was working fine but it mostly was in roaming and would go from 2-4 signal bars.
I backed up and have attempted to flash:
PACman
MIUI 2.11.23
As well as CM10 by joker and AOKP CM 10.
Every flash I end up with no signal bars and no roaming, also following all install instructions in the threads.
I have tried flashing with and without prop tweak, i have even restored the backup all with the same results:
Empty signal bars, occasional R for roaming, every call says mobile network unavailable.
I have also fixed permissions, and have tried to flash via TH3Bill CWM and TWRP recovery... what am I doing wrong? The backup isin't even working!
I wouldn't know off hand, but here's something you can try while waiting for a more professional member to come to the rescue.
System Settings> More>Mobile Networks>System select>Home only
What's your current PRL, APNs?
if it was me I'd sbf back to stock and see if I had signal then go back and try a custom rom again

Before sbf'ing if you have a back up of your stock ROM or any ROM that has the update profile/prl setting in it, restore that back up and try updating your profile/prl then wipe/flash your new ROM.
I usually have this problem when I switch back to my Photon from my ET4G, but updating the profile usually does the trick.
When I restored my old backup, I had the same problem. The only fix I could find was on MIUI and selecting automatic netowrk before flashing options chooser. Any other rom would make no changes on automatic or home only. I am going to try a fresh install and if no luck will sbf today. I'll keep you guys posted.
Thanks!
**EDIT** Does it matter if I use Th3Bill's CWM recovery or TWRP? I have tried both with similar results. I jut noticed CWM is usually posted with the ROM builds... does it makes a difference? If so, what should I use?
Normally both work just fine, as long as you're using one of those two
I spent too much time flashing roms and wondering why they wouldn't work right, when I was using the stock CWM
I think It's just my opinion but I have preference for bill's cwm
Having this exact same problem. Did anyone figure it out?
No Radio/Signal
I recently flashed the latest MIUI.US V5 3.4.5 for the Photon provided by Th3Bill. I am familiar with the process of applying ROMs. I tried to go back to Beanstalk, JB, and ICS and could not recover the radio signal. I even restored a few backups with the same result, no signal. I flashed the MIUI V5 3.4.5 ROM back to the Photon and it worked flawlessly. Can anyone please help? I would really like to get off the MIUI ROM, it does not appeal to me like the standard versions of Jelly Bean that Th3Bill has produced.

[SOLVED][Q][CM11] Mobile network state disconnected & phone wakelock

Due to instability issues in the latest nightlies, I clean flashed and reverted back to CM11 milestone 5. After doing this, I haven't been able to get mobile data. Voice and sms work fine, just "mobile network state disconnected" and no data connectivity. Also after flashing back to M5, "Phone" seems to prevent the device from sleeping. In battery stats, the device is always awake, with "Phone" using the majority of the batter.
I've tried re-flashing CM11 M5 multiple times, I've also flashed different modems, and I've also called AT&T to reset my internet connectivity. Nothing has worked thus far. Any suggestions? :good:
UPDATE/SOLUTION:
I got mobile data back by going back to stock, clean flashing AOKP (which works with mobile data), then dirty flash to CM11. Quite unorthodox, probably not the best solution, but it's the only 'fix' that has worked!!
I've tried many other suggestions, such as the "patched" modems & kernels, to no avail. Finally this works, dreams do come true
UPDATE: I tried ODINing back to stop 4.3 ROM, on which data was working again. However, upon flashing back to CM11, data stopped working once again. I tried flashing AOKP, which *did* get data back, so I'm assuming this is a CM11-exclusive problem.
I really don't know how the CM11 data problem persisted even after flashing back to stock and then re-flashing CM11. What could've gone wrong? Anyways, I guess I'm sticking to AOKP for the time being.

Have you got a link to the rom - any issues with Wi-Fi or 3G/Mobile Data? This CM 11 rom I have is awesome but it's a pain that the 3G/Mobile data just doesn't work at all.

If you look on that thread, try installing the specified modem and kernel. Hope this helps.

Did you install the patched kernel/modem while on stock ROM or on a custom ROM?

Got the 4.3 stock ROM from sammobile then installed the kernel and modem from TWRP recovery - haven't tried a custom ROM yet but I presume it'd work in the same way

After Update to 4.1.2 can't switch WIFI on :(

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.

No Cellular on Custom ROM

I had my s2 hard bricked and now i got a new motherboard for it, the thing is that on all stock roms (2.3 and 4.1.2) the phone works perfectly but all the custom roms 4.4 5.0 6.0 the cellular does not work, it gives me no service, tried flashing modem from cwm but no change.
i also tried different recoveries etc but custom rom no service
sometimes in custom rom imei used to be blank but it comes back after reboot, in stock no issues at all
any idea what im doing wrong or is there something up with the new board?
thanks,
Update
I was searching and I read somewhere that installing NeatROM by Sale will help, i downloaded and installed it, the good news is that cellular works and i have full 3G access.
Question: How to proceed further?
i could experiment but the thing is that if i flash a non-working rom (no cellular), i will have to flash stock from odin and start all over again
any ideas?
Update 2
i tried NeatROM and it worked perfectly, then i tried installing slimLP and boom, no service again, this time,my IMEI was blank too, so now i'm flashing stockrom again.
any idea anyone please?
