Just tried installing Zorin OS 16.2 on an old laptop and am having a problem with installing the drivers for a USB WiFi device.
The laptop is a Lenovo G780 and the built in WiFi card uses the BCM4313 chipset. However when this laptop is booted into Windows (8.1) I use a USB WiFi adapter instead because the built in BCM4313 is hopeless at any kind of range. The much better USB WiFi adapter uses the rtl8812au chipset.
I've installed drivers for the latter in Zorin OS and to test it tried to disable the built in BCM4313 chipset via the Software Updater settings under Additional Drivers but the built in device is still working as I can still access the Internet even with the USB WiFi device unplugged.
How do I ensure that the USB rtl8812au WiFi device is working instead?
If it is blacklisted and the module removed, it is pretty much impossible for it to still be working.
Did you reboot after blacklisting?
It may be the module name I am using in the commands I offered: brcmsmac
As I understood it, that is the driver name - but I could be wrong. As you know your own hardware far better than I, could you please check your hardware and see if we need to reference a different driver name?
This is an example of troubleshooting over the net based on available info and a lot of guesswork.
