[Q] GT-N7105 wifi problem on cyanogenmod10 - Galaxy Note II Q&A, Help & Troubleshooting

Hi,
I just moved from Note2 stock ROM (rooted) 4.1.2 to Cyanogenmod 10.1 (latest nightly build as of today) 4.2.2 and now my note2 does not connect to home wifi (verizon router and Apple router). I did some research and found out samsung has a bug in 4.2.2 where it cannot connect to wifi 2.x Ghz bands but connects fine to 5.x GHz band. I am stuck at this point as my note2 does not connect to wifi. Have you heard of this problem before?
I tried both the mentioned wifi fix on the below link but it did not help
(link)galaxynote2root.com/galaxy-note-2-tutorials/how-to-fix-wifi-hanging-problems-on-galaxy-note-2/
I am now thinking if I move back from 4.2.2 to 4.1.2 or 4.1.1 (Cyanogenmod) then I can get rid of the wifi problem.
If I have to move to 4.1.2 then I went to their website [link]get.cm/?device=t0lte and could not find the mod for the version 4.1.2 or 4.1.1 (for GT-N7105)
Kindly advise.

Hi, Have you fixed you issue? i'm having the same peoplem

[Q] Custom sense-based roms wifi problems

Hello everyone,
I owned HTC Desire almost a year ago and used with Cyanogenmod 7 all the time. I wanted to switch to any rom that comes with HTC Sense UI, but everyone makes a trouble establishing connection to wifi (all of them are 2.3 gingerbread). When i want to connect to network is says 'connecting and disconnected', so its impossible to connect. I bought it with radio v5.11.05.14 but upgraded to 5.17.05.23. First i thought it was radio issue, but no problems with cyanogenmod so far. Also downgrading back to previous version didnt solve my problems.
What might be wrong?
I tried:
* Supernova
* Cool3D
* Runny Rom
EDIT: I have just restored stock firmware shipped by device (2.2 Froyo) - yep i've done nandroid (there is even no root access)
And this problem still occurs. I cannot connect to WiFi So, really, the only rom with working wifi is cyanogenmod... What the hell?
EDIT2: After some more investigations looks like Cyanogenmod is able to connect to 802.11n wifi while stock-based mods not (b/g only). Can anyone tell me how is that possible that 802.11n compatible hardware is so limited by stock firmware and if it is normal? I would really like to be able to connect to N-only networks.
Thanks a lot for your help!

No WiFi

Got my phone rooted and installed CyanogenMod version 10-20121125-NIGHTLY-toroplus. now WiFi will not connect. It will see the networks and save them, but will not connect. It will broadcast as a WiFi hotspot.
Any idea on how to get it working again?
I suggest updating to a stable release I am running the most current version with virtually no problems

I tried 4 different releases and no WiFi was the best result, so I went back to the stock ROM rooted
Tried posting in cm thread? Could be rom related

WIFI working smoothly only on StockROM

Hi,
I have a T210R Galaxy Tab 3, which I flashed with different roms to try them. Unfortunately, I have observed that wifi on it remains connected and stable only on StockROM I used, whereas no other roms (stock ones included) have wifi stable. Wifi keeps catching and losing signals after few seconds/minutes. Any idea why is this happening? If there's a wifi tweak for this let me know. I'd be grateful.
Regards
UPDATE: Resolved the issue by installing T210 instead of T210R roms. Works fine on both 4.2.2 and 4.1.2 now
