Hi, I just installed EndeavourOS on my Raspberry Pi 4. My router’s wifi is in the 60 channel and can’t connect because some of the 5 GHz channels are disabled. The registered domain is set to US. The channels 32 to 48 works fine, because I can see my neighborhood SSIDs. With Raspberry Pi OS and with Manjaro everything works fine out of the box with the same registered domain.
thats because some 5GHz WiFi frequencies are also used for radar - they are disabled by some devices to avoid issues.
Google devices (at least the Nexus and Pixel devices in Europe) can’t see 5Ghz Wifi Channels 52 to 128 due to that (not sure if I remember the upper limit correctly but pretty sure about the lower limit)
Thanks for giving EndeavourOS Arm a try. Welcome to the forum, I hope you enjoy your time here.
This site has some instructions for adding WiFi channels in wpa_supplicant. Maybe that can help?

Thanks, that’s right, the channels disabled require DFS/TPC to avoid radar interference, but that doesn’t explain why with Manjaro works fine, but with Endeavour are full disabled in the same Raspberry Pi 4.
Thanks, I try the wpa_supplicant fix, but didn’t work. I think the problem probably is in the driver, because the iwlist list of available frequencies doesn’t report these channels:
[root@raspi4 juanp]# iwlist wlan0 freq wlan0 20 channels in total; available frequencies : Channel 01 : 2.412 GHz Channel 02 : 2.417 GHz Channel 03 : 2.422 GHz Channel 04 : 2.427 GHz Channel 05 : 2.432 GHz Channel 06 : 2.437 GHz Channel 07 : 2.442 GHz Channel 08 : 2.447 GHz Channel 09 : 2.452 GHz Channel 10 : 2.457 GHz Channel 11 : 2.462 GHz Channel 36 : 5.18 GHz Channel 40 : 5.2 GHz Channel 44 : 5.22 GHz Channel 48 : 5.24 GHz Channel 149 : 5.745 GHz Channel 153 : 5.765 GHz Channel 157 : 5.785 GHz Channel 161 : 5.805 GHz Channel 165 : 5.825 GHz
then it might be an update that changed the driver behaviour, that most likely is not yet available on other distributions. Manjaro always hangs behind some days to weeks.
