[vox-tech] Internet connectivity issues in 20.04

[Austin Miller]

Hello to whomever is reading this,

For the past several days, I have been unable to enter my WiFi network. At first I was on Sonic which worked for months with my Ubuntu 20.04 Lenovo ThinkPad laptop, but then the laptop became unable to load Firefox, the snap store, my ProtonVPN, etc., even though the WiFi signal sign showed a very strong signal. I eventually decided to reinstall Ubuntu 20.04 without updates, believing the issue was related to the routine updates I had received the night before. This worked for a day and a half, but then one time I turned on my laptop and the same problem as before was occurring. The network switched to ATT, which also worked fine for that brief period of time, being fully detected. Now my laptop doesn't recognize the new ATT network, only the old Sonic one somehow, which is oddly shown as still having "good" strength despite no longer existing. I am even notified each time I turn on my laptop that I am connected to the printer, as I was before. Yet I am unable to do anything requiring an Internet connection. I have followed Tim's advice with this link: https://phoenixnap.com/kb/ubuntu-dns-nameservers . This solved nothing, and I am still unable to connect to my home Wifi network. I have attached a couple of text files of output from my terminal that may be of help, because I am forced to write this on a family member's Windows laptop. I even tried reverting to a prior kernel version in GRUB, and this seemed to make no difference. I am pretty sure the issue is DNS, but I don't have the knowledge or skill to fix it. If anyone could help, I would be very grateful.

Thank you,
Austin Kingsbury Miller
