Specific wifi connection not shown broadcom drivers nightmare
I have a broadcom bcm4313 pciid 4727 rev01. I'm using Ubuntu 20.04
Today, my home wifi was not showing from the wifi list. However, it showed on my other devices and I was seeing all the neighbors wifis.
It realised that if I uninstalled the "additional drivers" bcmwl-kernel-source and reboot the computer, the wifi was showing again. But wifi was horrible. I installed brcmsmac since it's the only driver working with my adapter.
Sadly, it still was horrible and lately I can't even use the wifi, i get the question mark icon and sometimes it cannot connect.
Note that I can still connect to all neighbors wifis and that only my wifi disappears when I change to additional drivers's driver.
I tried everything b43, wl, bcma, brcmsmac, etc.
Edit: lsmod
