After updating the kernel to 5.8.0-36-generic
and rebooting I noticed the network wasn't working.
Using the previous working kernel I've found that the problem was related to drivers not present because my interfaces were UNCLAIMED
using lshw -c network
.
I've found other posts suggesting to install the linux-generic-hwe
in my case linux-generic-hwe-20.04
.
After installing it the interfaces where recognized.
I can't quite get what happened, and probably don't quite know where to look for information about this, the previous kernel worked fine.
I don't understand if the driver was removed between kernel releases or something else..
The output of sudo lshw -c network
with the network working is pasted here:
*-network

So it looks is something related to iwlwifi
.
Anybody can give any info regarding this, the update process finished with no errors, so I guess it's something else.

Also lost network connection after updating from kernel 5.4.0 to kernel 5.8.0-41.
Looking at the output of
I figured out that in my case the previous kernels had
linux-modules-extra-
packages installed, butlinux-modules-extra-5.8.0-41-generic
was missing. After booting a 5.4.0 kernel (with working network connection) I could fix the problem by
