[Q] Weak Wi-Fi signal - Galaxy Note II Q&A, Help & Troubleshooting

Hello.
I have flashed my Note II with ReVolt JB (stable) following all developer instructions and after that my phone can't connect to my router because of low signal level as it thinks.
Wi-Fi connect is only possible if i place Note on the router. I came from the stock ROM and everything worked properly. I changed Kernel to AGNi 4.2.2 Auto OC but nothing became better.
Can anyone tell me what's my error?

Sounds like a radio issue. Reboot your device and see if you still encounter the problem. If so try flashing a different radio.

[Q] wifi radio files for GSM GNexus.

I flashed jelly bean on my google playstore GNex. since then the wifi performance has diminished. my laptop, ipad, printer and tv, all in the same room have full 5 sticks of connectivity whereas my nexus randomly changes between 1-3 sticks and sometimes drops for no reason. i have flashed the verizon wifi fix posted earlier but the problem seems to have worsend a little. it was fine when i was on 4.0.4. can someone suggest a fix or give me a flashable file of 4.0.4 wifi radiofiles? Any help would be resoundingly appreciated. thanks a lot in advance.
wifi "radio files" are within the kernel.
try franco kernel r210 or trinity's jb kernel
thanks for the quick reply. simply flashing them via cwm will do? will that change anything else other than wifi? thanks.
I have the same issue with weaker WiFi signal. I would rather stay on the stock kernel for now so any help would be appreciated.

read what a kernel does......
@krnchicken753: cant complain when the 'possible fix' is there but you aren't willing to try it. you could always go back to ics which is more stable.

[Q] Wifi Issues after Stock ROM

I Installed back the Stock ROM Buzz_Froyo_hTC_Asia_India_2.25.720.1-dannejo.zip and also flashed its Kernel to InfinityPLAY
but now, my wifi is not working, it keeps on SCANNING..
Even tried to FLash the Radio to Radio_13.55.55.24H_3.35.20.10
but nothing working !
So things not working are:
1) WIFI
2) HOTSPOT
3) GPS
4) Bluetooth
Prior to this, tried Cyanogen 7.2 and 9.1 mini ! but didn't liked them as compared to Stock ROM.
though 9.1 had Hotspot n GPS issues!
so someone, suggest a solution !

Has to be a radio problem. Maybe you didnt flashed it correctly. Just flash it a 2nd time and search a guide on xda how to do it
Only GPS not working fine

yeah bud, i know, it has something 2 do with Radio.
I once again, did flashed my Stock ROM but this time i wiped each and everything.!
Now Wifi, Bluetooth, n Hotspot are working, but Except for GPS
GPS still shows location on the basis of Network, not GPS satellites
So the only thing left is GPS !
now what else can i do to solve it?
and I even wish to change it Kernel, to OverClock it..! suggest me a stable one!

Wi-Fi on custom ROMs

Last night I tried flashing cynogenMod 10.1.3 on my stock 4.1.2 Note 2. I followed their instructions, and everything went well but the Wi-Fi never connected to my router. It stayed saying connecting... then network saved. The password was correct. I restored my backed up ROM and on it the Wi-Fi was working. I flashed the cynogenMod Nightlies 10.2 and the same problem was there. I downloaded a stock ROM and flashed with Odion, and the Wi-Fi worked. I flashed Ressurection Remix ROM and on it as well the Wi-Fi didn't work. I tried a few non touchwiz ROMs and all of them the Wi-Fi didn't work, it only works on stock ROMs and TW based ROMs. Is there a way to know more about the cause of this issue? Did other experience such an issue as mine?
I would be greatly obliged if anyone can offer me help.
I have tried many custom roms of every type and build, never had any issue with wifi
perhaps you can try to setup static ip address on the connection instead of DHCP, see if that helps, or try installing something like wifi manager from the store, and use it to connect, see if it gives any more info ?
sorry if this doesn't help, can't think of anything atm

Note 2 WIFI not turning on (ND3 Bootloader)

I am having issues with turning on WIFI in my Rooted Galaxy Note 2 GT-N7100.
Background: After facing various slow down and WiFi drop issues with my Stock 4.3 ROM decided to Root and install custom ROM. Rooted and Installed C-ROM 7.1 on device. Everything was working fine initially but after few days WIFI signals just drop and after that it just wont start. Again flashed and installed DN3 V5.2 LIte ROM,
Problem: Still WIFI wont start, it starts sometime after reboot but keeps scanning and can not detect any WiFi signal and after few minutes it wont start at all.
Solution Tried:
1. Tried Dr. Ketan WIFI Fix multiple times, still no solution
2. Can not downgrade Bootloader to MJ5 because its already on ND3.
3. Tried multiple modems (ND1, ND2 and ND3), no help, getting strong 3G signal but WiFi just wont start.
Current Phone Config:
Device: Samsung Galaxy Note || GT-N7100
Android: 4.4.2
Boot Loader Version: N7100XXUFND3
Kernel: Linux
Kernel Version: 3.0.31DN3
I am not an expert, so please pardon if my question is not clear. Any help will be appreciated. I am OK if i have to unroot or complete wipe my device.
Hardware Problem!?
Looks like something is wired with phone WiFi hardware. After flashing ND2 modem WiFi actually started to work, but stays connected only when signal strength is very high, as soon as signal goes low it drops the connection and never connects again until and unless I reboot the device or go to Airplane mode and come back.
Any suggestion in this regard is welcome otherwise I have accepted this problem as Hardware problem rather then software problem and going to live with it till the time get some good deal for the device.
Exact same problem. but no solution so far.

I've got exactly the same problem.
Tried from Dr.Ketan's patches, to others wifi fixes, modem fixes, and even others ROM with no luck
Now wifi keeps scanning all the time. :crying:
Current phone config:
N7100XXUFND3
Android: 4.4.4 (just upgraded this morning but still no luck)
Kernel: 3.0.101-India-v4.2.5-OC-INTL-Kitkat
Any help would be appreciated!
Solved
Just an update, I've followed some comments below the video and now my wifi works like a charm.
It seems that the note II housing was the cause, hope it might help you too.
