374.40 No 5ghz on Galaxy Nexus

[williamsje85]

So, kind of strange, but when I updated to 374.40 my Galaxy Nexus can no longer even see the 5ghz network. Other 5ghz devices don't seem to have a problem. As soon as I jump back to 374.39, it works just fine. Is there a new setting in 374.40 I'm missing or something?

Did you power cycle the router after you updated? A couple times Ive noticed weird stuff after a flash till I hit the power button one time. A Factory Reset would be my next step.

Try changing the 5 ghz channel to a lower one. Some devices like my galaxy tablet 10.1 only see 5 ghz in the lower channels if I use a higher channel it don't see 5 ghz at all like it's not there. Just a suggestion you can try.

Galaxy Nexus has a big problem with DFS channels.
So you will not be able to use anything above channel 52. 36, 40, 44 and 48 may work for you. I'm using channel bonding 36+80 and my GN doesn't even see 5GHz. But it may work if you don't use channel bonding or you bond 2 of the supported channels.

And no, Google will not fix this for the same reasons they weren't able to put 4.4 on GN.

I can't explain why, but when I went from one of the 40 beta builds to the latest version, I can also comment that my 5Ghz radio disappeared. Not obviously so (the occasional client connected ok, but most of the others could not see or join it). I think it may have been because I went from a non -EM wireless build in the original scenario (which router hardware are you using - doesnt say in your original post)

The only way I found to fix it was to do a factory reset and start from scratch.

If it helps, I'm using a Galaxy Nexus i9250 on .40, AC66U. I needed a very clear channel to connect, noise better than -80db. Too much noise on the channel and it had issues connecting to 5ghz.

Here's all my specs;

RT-AC66U 5ghz
Wireless: Auto
Bandwidth: 80 MHz
Control: 161
Ext: Auto
Auth: WPA2-Personal
Type: AES

I9250
Running beanstalk 4.3.07-20130830
Kernel: 3.0.93-4.2-fancy_kernel-r40-ext
Radio ver: I9250UILH1

I have a Rt-n66u. I'll try to do a factory reset and see if that helps. Thanks for the tip.

Actually it works of you are 20 cm. away from the router it sounds like amplifier of 5Ghz module is fault.
