To install VPN from university in Ubuntu 22.04 I did these steps: https://www.ccuec.unicamp.br/ccuec/m...inux_vpn_18_04
Now wifi native driver just works there in the university, but not in my home. I tried removing access to the network, but just with antenna.
These commands can give you some information.
sudo systemctl restart NetworkManager works with ethernet cable but not with wifi native.
