After upgrade and reboot the system does not recognise the network device

After upgrade and reboot the system can not see the network device.

I just upgraded and rebooted my system, latest stable kernel version 6. Now, it says that I do not have a network device.

When I run ‘inxi -n’ I get the result “no pci device data found”.

Any ideas how I can get my system online again? (Writing this from my phone)

( there are at least 3 major kernel 6 series available - 6.1(LTS), 6.6(LTS), 6.7(RC) )
(( its also possible you have another one installed, which is likely end-of-life, such as 6.5 ))

But instead of relying on that we could use reporting tools;

inxi -Fazy

Probably mhwd too (for drivers)

mhwd -li -l

And mhwd-kernel (for, er, kernels)

mhwd-kernel -li

Thanks for your reply, @cscs! I appreciate your help.

Weirdly enough, the network started working again. What I did was rebooting into kernel 6.5.13, to check if that made any difference. It did not. So, I rebooted once more, and chose kernel 6.6.7 again. And now, by some unknown reason to me, the network is working fine again. So I am writing this post from my PC.

Maybe something was “stuck” after upgrade, that was completed after doing this process? I have no idea…

If this happens again, after another restart, I will report back. However, I hope all is good now, and this was nothing but a “glitch in the Matrix”.

The 6.6.7 kernel release fixed an apparent regression in previous kernel versions, that caused issues with WiFi for many users. This was mentioned in the Stable Update 2023-12-10 announcement Broken Wifi with 6.1.66 and 6.6.5 kernels.

If you are using WiFi, choosing the 6.6.7 kernel is likely the reason for this magical transformation. Are you using WiFi? :magic_wand: :sunny:

Yes, @soundofthunder. I am using WiFi, so that might be it. Thanks for this info.
