Description Anthony Guevara 2021-11-08 15:44:31 UTC

I had to downgrade the linux-firmware package from version 20210818 to version 20210716 to get my wifi working again. sys-kernel/linux-firmware-20210818 broke my wifi.

please attach the kernel .config. Please give some more details on the hardware. For example with sys-apps/inxi
inxi -Nx

For some time I thought I had the same issue, but it turned out it is:

https://bugs.gentoo.org/865017 (networkmanager defaults to iwd now)

and my iwd service was not started. Maybe this is helpful for someone else who is stranded here :)
