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.

Input the working BSSID into the BSSID field.

On your desktop, go into Settings -> Wi-Fi -> Settings (for your specific SSID) -> Identity.

Identify working BSSID by reading through sudo dmesg.

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.

I have not been very successful in finding much information on how to diagnose/resolve this issue despite several hours of reading forum posts and trying suggestions. I usually am connected just long enough to establish a dhcp lease and then the network disconnects again.

I have installed the Realtek firmware using apt-get install firmware-realtek and confirmed that it is in use using modprobe rtl8821aeWhen I connect to the wireless access point I can maintain a connection for ~6 seconds. I confirmed the support for the chipset at. I just added a D-Link DWA-582 PCI-e WiFi adapter using the Realtek RTL8812AE chipset.
