I've come across an interesting problem where I am unable to see any wireless networks (or manage my wireless connections) from the user interface (Gnome 42), but I am both connected to the internet and able to manage this connection from the terminal.
For context, I installed Linux (server version - Ubuntu 22.04 LTS) a few months ago to get comfortable with the terminal before I moved to it as my daily driver. I added Gnome 42 a few weeks ago and have been using the wireless network I initially added when I did the server setup.
Is there anything that could cause this?
Further, I'm also unable to switch networks from the terminal - if I use nmcli dev wifi connect NETWORKNAME password PASSWORD, I get an error - No network with SSID 'NETWORKNAME'. I double checked the wireless network names with iwlist wlp4so c, so I know the ESSID is correct
That said, I'm unsure if this is related, or a separate issue to the initial one - I'm quite comfortable with working on my own machine (making new files, changing permissions, troubleshooting non-network related issues, etc.), but I'm quite new to troubleshooting network issues.
