I have a laptop with a proprietary Intel wifi card that I am trying to use to connect to a WPA/WPA2 network (called simply "Network")
I've installed iwlwifi, net-tools, and network-manager
I ran nmtui to set up the wifi, and all seemed well, and nmtui reported it was connected, but when I tried to ping 8.8.4.4 I got an unreachable network. For some reason nm[cli|tui] does not work. I've also tried wpa_supplicant, but wasn't able to get very far with that either.
I'm hoping that there's some error in how I've set up my wireless interface that someone can spot and help me fix.
I know that "Network" works because I am duel-booting Ubuntu alongside the Debian system and I have wifi working with Ubuntu.
