I am working on a HP ProBook and Ubuntu 22.04 and have the problem, that when trying to connect via WiFi that no WiFi adapter is found.
As I am not really practiced with Ubuntu, I tried my best to follow forum recommendations I found but soon came to my limits:
I tried the following steps:
- Reset BIOS to default setting, but turn off Fast Boot in BIOS.
- Check if the right drivers are installed.
- Check if iwlwifi is working (came to an error message I wasn't able to resolve).
