[SOLVED]Broadcom wireless not working (BCM4311)

[Fmamarksman]

I have broadcom wireless chip BCM4311. In Debian, normally I need to install the firmware-b43legacy-installer package to have functional WiFi. However,
that doesn't seem to work for me on Mint. I have also checked the driver manager program and confirmed the bcmwl-kernel-source is in use. I reinstalled it, but had no luck. I also tried the firmware-b43-installer package, but that didn't work for me either. Any ideas?

Remove the bcmwl-kernel-source

Code: Select all

sudo apt remove bcmwl-kernel-source

Reboot

[Fmamarksman]

Done. No noticeable difference. ip a still doesn't show wlan0.

Works now, thanks. I wonder why it didn't before? Did removing the bcmwl package make the difference?

[JeremyB]

The bcmwl package blacklists the ssb and b43 modules so even if the firmware is installed, the modules won't load
