I am using Ubuntu Bionic.
Somehow Ubuntu can't detect or display low bar signals to a Wi-Fi that shows 2 bar on my Android, I even tried a Windows machine and it displayed 3 up to 4 bar signals.
Is there a way to solve this? Why Ubuntu 18.04 (or the one I have at least) can't detect close ranged Wi-Fi?
I have run the network diagnostics; here is the output
