Networking and servers • Re: Rpi4&5 Can't connect to 5Ghz WiFi, but can to 2.4Ghz.

Channel 149 is a safe channel because it doesn't require DFS nor TPC in Brazil and most other countries so that is good.

The router's version number or serial number should have something that indicates what country it is configured for.

Linux has had mistakes in the country wireless settings in the past and RPiOS appears to be the only common factor as you are using two Pi's and two completely different routers.

You could cheat a little bit and set the Pi's wireless country to GB just for test purposes, that would test if it is a country configuration problem in the OS.

Hi pidd,

I could not find any country info.

But you are pointing the right target.

According to your previus comments, about 1 hour ago i set up country to US and I am happy to say: ISSUE SOLVED.

Now I can see 5g WiFis, mine and the neighbors WiFis.

This means that the router is US, and also means that Ubuntu is US too.

Now I'll contact router support. If no solution, now I know what to do

Thank for your smart and constructive comments,

Cury
