Hey,

I am new here and not sure if this is the right place to mention the problem. The wifi on my Dell XPS 13 9343 stopped working after upgrading to elementary os 7.1. Just after the installation it worked fine, but after the first run of updates it stopped working.
When I run: sudo lspci -vvnn | grep -A 9 Network
I get:

What has gone wrong?
