WiFi stopped working after updates. [Solved]

ok do you have a vpn?

Yes, and I tried it with it shut down. Didn't make a difference. WiFi was working before the updates.

the wifi is working now. that namesever address that is in your resolv.conf file is one typically handed out by VPN clients and its totally local. for whatever reason its not working or changing back to something else once you disable the VPN.

you can manually edit /etc/resolv.conf to have

Code: Select all

nameserver 1.1.1.1

and see if that works. (1.1.1.1 is cloudflare's public dns server). No reboot necessary.

since the ping was blocked and the message reported by the local router, its also possible that the local router is blocking your wifi's MAC address, but not your ethernet address. I would think that weird, but its possible.

I
It's named to that already which is why it won't change anything. I tried something different on my own. I rebooted the modem and it worked. Seems like something in the update made the WiFi get blocked and resetting the modem made the rooter and modem communicate again. Thank you.

Just to note that you are running the latest 5.19 backported Debian kernel we added to AHS, and that is not an update or upgrade of anything--the user has to specifically install that, usually using MX PI.

Sometimes newer kernels require different firmware files, even for the same hardware. Your particular Atheros driver may not require any non-free firmware---I'm not really sure, though most do nowadays---but we recommend that users of the 5.19 kernels also install "linux-firmware", which is up-to-date, and will remove and replace a lot of Debian firmware packages, per design. Debian hasn't updated their firmware packages upstream for well over a year now.

Another troubleshooting tactic would have been to boot into the 5.10 Debian kernel--I see that was updated automatically, like it does in MX 21.
