Linux Mint 19.2 Cinnamon Wifi drops on Macbook pro mid-2012

[happysadhu]

Often my wifi connection drops out on my macbook pro mid-2012 even though the taskbar indicator in Cinnamon 19.2 still reports that I am connected. I have to disable and then re-enable Wifi to reconnect. Disabling Wifi power management and IPV6 doesn't appear to help. It could be a router issue. However, my Windows 10 laptop doesn't have the same problem. I am using the proprietary bcmwl-kernel-source driver, installed through Mint's driver manager. Is there an open-source driver I can try?

You can try following this suggesiton.

First, remove bcmwl-kernel-source package.

Code: Select all

sudo apt purge bcmwl-kernel-source

After, install firmware-b43-installer package.

Code: Select all

sudo apt install firmware-b43-installer

And reboot your PC.
