System not detecting WiFi after upgrade to linux64

Yesterday I have upgraded from linux61 to linux64 kernel and rebooted the system to apply the changes and use new kernel. And then put it on the sleep, and now I am checking the broadcom drivers were not installed, so I installed it and still after reboot it is not detecting WiFi

Even RFKILL is showing bluetooth now

I am writing this post from USB tethering from my phone. I haven’t tested ethernet also but based on lshw output, it appears ok to me.

Hi @tbhaxor,

Have you tested with another kernel? Also, have you rebooted?

Also, please post the output(s) of:

lspci

…and:

lsusb

…and:

inxi --admin --verbosity=7 --filter --no-host --width

Linux 6.1 will be supported until the end of 2026, so you can safely keep using it.

Its not working on linux61 also now :man_facepalming:

Ok so brcm80211 is blacklisted

$ grep brcm80211 /etc/modprobe.d/linux64-broadcom-wl.conf 
blacklist brcm80211

Ok, so new finding. Even with live boot usb it is not detecting WiFi, could it be a hardware problem? How can I confirm?

By providing what I asked for earlier:

Ok so this is a weird fix. I removed the wifi module, cleaned it and reinserted it. Now its working perfectly fine. :sweat_smile:

That does make sense, yes. Well, I’m happy for you.

Just goes to show:

Just chipping in to say that linux64 went EOL and you should migrate away from it, see
https://kernel.org/

stable: 6.4.16 [EOL] 2023-09-13
