When I did a fresh install of 22.04.03 on my Dell 5510 laptop a week ago all network devices worked w/o any issues. That includes Bluetooth, WiFi and wired Ethernet via a Dell USB-C docking station.
I’ve spent the last week moving my projects from 22.04 to 24.04 and I’ve rebooted successfully dozens of times without any issues.
This AM Ubuntu boots but ALL of my network devices have disappeared.
All network devices still work when I boot from the install disk and select try Ubuntu so clearly it’s not a hardware failure.
Yesterday I was moving a wxPython base project and ran into a known issue with version 4.2.2 and Python 3.12 so I installed Python 3.14 and wxPython 4.2.4.
I’m guessing that I ran an apt update that messed up my networking, but I have no clue how to fix it.
I downloaded the wireless info script, copied to a USB drive and ran it.
Here are the results:
