When I was running into connectivity problems, my log looked like and endless cycle of this: After my computer authenticates successfully, it then attempts to fully connect (associate) with this same address. In the above, perfectly healthy example, my computer first attempts to authenticate with the WiFi address 86:a0:6e:ee:a5:67. If this command doesn’t return anything, try sudo dmesg | grep 'wlan0', or just manually search through the results of sudo dmesg until you find the section of the log similar to the snippet above. IPv6: ADDRCONF (NETDEV_CHANGE ): wlp2s0: link becomes ready wlp2s0: Limiting TX power to 30 (30 - 0 ) dBm as advertised by 86:a0:6e:ee:a5:67 Ideally, this should return something like the following: When experiencing a disconnect / reauthentication event, run sudo dmesg | grep 'wlp'. It’s easies to just ‘Forget’ the original SSID. MAKE SURE YOU DON’T AUTO-CONNECT TO THE ORIGINAL SSID. One of these is the SSID+BSSID combination you just specified, and the other is the original SSID. After doing this, you will likely see two entries in your Visible Networks with the same SSID. This forces NetworkManager to use a specific BSSID when connecting to the SSID.

Ubuntu 20.04 frequently disconnects from WiFi and prompts for password.Here is the hack I used to fix the problem. I would input the password, and it sometimes reconnected, but sometimes it just immediately prompted me for the password again. Installation of Ubuntu 20.04 LTS was successfull, but when I tried to connect to my WiFi I ended up with a frustrating problem: I would successfully connect, use it for a few minutes, and then it would disconnect and re-prompt me for the password. I recently built a desktop out of spare parts I had, which I intended to use solely to run Linux.
I couldn’t seem to find any existing solutions to this particular problem, so I figured this is a good opportunity for me to contribute something! There are a ton of reasons why you might end up with a finnicky WiFi connection when using Ubuntu (just try googling ‘WiFi randomly disconnecting Ubuntu’), and I believe I have found yet another.
