Every couple of minutes, I receive a notification telling me that authentication is required. Clicking it prompts me to enter my network's password, but all I do is click "Continue" as the password is saved. In between these occurrences, my internet connection performs normally.
Current Potential Issues:
- Being deauth Attacked (Unlikely as nothing on our home network would do this. Also, there are no deauth packets detected by Wireshark.
- Interference/Weak Connection (Unlikely as this happens within 1 foot of the router.)
- Bad Driver (Unlikely as I've been using this device with 20.04 since this April, and the issues started this month)
- Issue with the Router (Unlikely as nothing has been changed in a while)
I've been using my home network for a while and it's been fairly reliable. We've never done much to the router except a bit of port forwarding, but all that happened a while ago.
I don't recall when this started, but every couple of minutes, I get this notification.
It only happens on my laptop running Ubuntu 20.04. I have 2 other devices on the network running Ubuntu 20.04 (1 desktop and 1 server) and neither have issues like this nor does anything else on the network. I can click on the notification and it asks me to put in the password (which is saved, so all I do is click "Connect"). It can range from anywhere between 10 minutes (maybe more) to 30 seconds.
And the worst part is that a reboot won't fix it. I've checked for updates, installed them, and it says everything is up-to-date.
EDIT: I have logs for NetworkManager: https://pastebin.com/jCGwwXzJ Additionally, I've tried erasing the connection a couple of times from gnome-settings and nm-connection-editor. I've also made my gateway forget my device.
I tried using WPS on my latest attempt, and I still am asked every once in a while for my password.
EDIT 2: I have another partition running 18.04. The issue does not show on that partition. Additionally, I used my phone as a hotspot and the issue did not appear on my main partition running 20.04. This seems to be an issue when running 20.04 connected directly to my home network...
EDIT 3: I don't think I'm missing any firmware. I'll be running a few more tests, but I think this may be related to gaming. It happens frequently when on Minecraft, Among Us, or on a Discord call. Yes, I play Among Us on Ubuntu. Sometimes this happens on YouTube as well.
EDIT 4: I've noticed that the area with my wireless card is rather hot. Could overheating be the cause?

NOTE: I have limited access to the laptop due to another issue (unrelated to Ubuntu). Please be patient if I do not respond in time. Best of luck to all trying to help me with this!
