Wireless N (5ghz missing after installing ROMs) - Galaxy Note GT-N7000 Q&A, Help & Troubleshooting

Good Evening All,
I've search XDA and the internet and I would like some help, please...
After installing several different ROMs I still cannot connect to the 5ghz wireless network in my home. I have an ASUS Dark Knight RT-N66U with two separate networks 2.4Ghz/5Ghz.
I've tried this from ROCKET ROM JellyBean v3 (which is my preferred ROM) but no luck. I've rooted my wife's SGSII and she's running SlimBean and cannot see the 5Ghz network either.
The strange this is that our friend has a SGSII running stock GB and the device sees the network...
I'd hate to have to got back to ICS (oh, BTW, I'm currently running Ultimate N7000 XXLSC JellyBean 4.1.2 v5.1).
Any help will be greatly appreciated.
Thanks in advance!

Thanks - can a mod move this to Q&A?

You should play with the router channels a bit.

It also depends on regions. Not all regions use the same wifi frequency so try to change modem.

Did you try another kernel as well? Maybe it's a release issue. You could try a newer build like gb2.3.6.
It could be a modem issue too.

Happened to me too.
I initially flashed KG3, but right now I'm using the one that comes with LANIGHT 8.0 (totally recommend that rom btw) it's KC1 I think it works a bit better (might be just my impression).
Good luck!!

If your rom is jellybean, ics, cm, miui, or similar then u need to use i9000 modems for those. See this thread... http://forum.xda-developers.com/showthread.php?p=16843698
These modems specifically... http://soggycashew.weebly.com/cm7miui--ics-modems.html

[SOLVED] [Q] [ROM][4.1.2 JB]Ultimate N7000 XXLSC JellyBean 4.1.2 v5.1 wifi problem

Hey..
ok so I've noticed that right after I started using my Note with the Ultimate Rom installed, the wifi connection has become both weaker in signal perception, and MARKEDLY slower than it was before I did the upgrade, and much slower than other devices connected to the same wifi.
I must point out that I have not noticed any negative change in the 3G/H+ connection. That is working just fine.
Has anybody else faced this problem? and can anyone help me with a solution or an idea?
Thanks..
Ultimate Fan too
Am on XXLSC V5.1 and i cant find this problem with WI-FI.
But sometimes Wi-Fi cant connect and i need to turn it off and then on again.
Well i dont know what wrongs with your note...
not to me
Im using this ROM also on my n7000 but everything works just fine..

[Q] WiFi not working on SuperNexus 3

Hi,
I fleshed SuperNexus 3 Bulid 1 ROM on my GALAXY Note GT-N7000 and now my WiFi not working and can't connect to any wireless router. Please help me. I don't like to downgrade to JB 4.1.2 again
I haven't used SuperNexus for quite some time now. But what you could try to do is to reflash the ROM after a clean install (formatting /system /data /preload) cache and dalvil cache, all while on a safe kernel. Another suggestion would be trying different modems.

Thanks a lot juliobahar for your reply.
I always flash any ROM after a clean install, but this problem seems that can't be solve on my device
try a different kernel

First, I flashed SuperNexus 4.1.2 and everything was OK. Then, I flashed SuperNexus 4.2.2 and finally 4.3, but Wi-Fi not working. When I see the screenshots of other users with this ROM, it seems that they haven't this problem and this issue isn't reported. Is this problem related to my kernel?
what rom are you on now?

No. On the current ROM everything is perfect.
Dear nokiamodeln91
I solved the problem on SuperNexus 4.2.2 by the WiFix application:
http://forum.xda-developers.com/showthread.php?t=1445766
But this solution does not work on 4.3
What exactly doesn't work with your WiFi, doesn't it turn on and can't connect to your AP or you can't switch it on at all?

My Wi-Fi turns on, but does not show my wireless network. On 4.2.2, by using the WiFix application I solved this problem and changed my country code, but this solution does not work on 4.3.
