Linksys WRT3200ACM 5ghz Wireless doesn't work

Ridik · January 28, 2022, 1:05pm

After migration from original fimware to OpenWrt 21.02.1 I configured 2.4ghz and 5ghz Wireless but my devices doesn't see 5ghz Wireless.
What can be the reason for this?

 OpenWrt 21.02.1, r16325-88151b8303

Have you tried 80 MHz instead of 160 ?

Ridik · January 28, 2022, 2:16pm

Did not help.

DeepAnger · January 28, 2022, 2:19pm

I don't know how you did your "migration" but the original firmware may still be in your router. You could switch back to it to check what channel was used and define the same in OpenWrt instead of using auto.

One way to reboot to Linksys is using luci-app-advanced-reboot

Ridik · January 28, 2022, 2:46pm

I changed the channel from "auto" to 153 and width 80Mhz - it works.
Thank you for your support!

Keep in mind there is a significant wifi bug for mvebu targets, yours included, in 21.0.2.1. It's fixed in master and will be fixed in upcoming 21.02.2.

@DeepAnger @phinn
I have a few issues with 5ghz Wireless:

5GHz is unstable when the width is 80 MHz. It looks like Wi-Fi is rebooting. 5GHz connection keeps dropping out.
5GHz is stable when the width is 40 MHz, but periodically mobile-phone on Android 12 does not receive packets. This happens when the phone is inactive. If I reconnect to wifi, everything works fine. This problem was not observed on a laptop with Windows 10.

hi all I have the 32x and the 3200acm linked together while also using the 2.4 G channel. to use 160 band width the 3200acm only uses one channel in 160 thats channel 100 manual set but if you have older wifi hardware wifi 5 and older it just reverts to 80 width. yes 160 width is very fast.

DeepAnger · February 1, 2022, 7:52am

I'm sorry that I can't help more. This router wifi is so bad that I don't use it anymore. An old RT-AC68U gives a way better coverage. Same with a Mikrotik wAP ac. I'm trying to sell it now. That open source fairy tale becomes a bad joke with wifi.

Hello all,

@Ridik I also have a recommendation, wrt1900acs v2 runs smoothly with the following installed packages , I create my own images with the online firmware constitution from @aparcar https://chef.libremesh.org/ https://asu.aparcar.org/ !

all you have to do is follow my recommendation with the following custom packages for different versions:

at the moment I am running SNAPSHOT 19.07, I saw that the latest version of SNAPSHOT has problems lately!

21.02 SNAPSHOT also runs well without problems, only it can't get 1Gbps on the wire side !
