A while after getting a new router, I started experiencing a problem with wireless networking on my Ubuntu 20.04 laptop. When I turn it on, it detects my wireless network and connects to it.
However, the connection breaks soon after I log in, or after a few hours. Sometimes, I need to restart Ubuntu three times until I get a seemingly stable connection.
When I lose the connection, I can't even see the Wireless (WIFI) option in the settings.
This isn't my field of expertise, so I'd appreciate it if anyone would help me.
Here are the logs and outputs of some commands. Note that I'm currently using a wired connection and that I got these logs and outputs after the wireless connection broke.
