[SOLVED] Sudden loss of wifi access

I'm dual booting macOS and Arch Linux. About ten days ago I lost wifi access to the Internet from Arch. It had been working for months without any problems. Notably I no longer receive an IPv4 address on startup. All other devices on the local network, including the macOS partition, have had wifi access. Ethernet access via USB seems to be fine.

I'm using netctl. Pastes below: wifi-menu, ip, netctl, dmesg, lspci, journalctl.

Anyone have any ideas? I almost broke the system trying to fix this, and I'm stumped. Thank you.

$ sudo wifi-menu

$ ip link

At this point I bring the interface down, because `netctl` will bring it up.

Re: [SOLVED] Sudden loss of wifi access

On a glance I'd assume a bug with the new wpa_supplicant release/compat change with netctl and this interface, try downgrading that to 2.9

Re: [SOLVED] Sudden loss of wifi access

That isn't really a sustainable solution, you should check whether it's an actual bug in wpa_supplicant or just in netctl's usage of it. Potentially check whether you can still connect on the new wpa_supplicant by establishing the connection manually: https://wiki.archlinux.org/title/Wpa_su … th_wpa_cli but I wouldn't think it far fetched some weird compat issue with the wl module and the changes in wpa_supplicant.
