I am new to ubuntu/Linux. I just installed 22.04 LTS on my macbook. Everything seems to work well except network. Here's what I see under Network section

Here's the output from lshw -c network.

Looks like I already have driver for wifi. But after some research I have seen people say that I should install a different driver. I saw this post here. However, it does not seem to be my situation. I checked the currently loaded modules and it shows b43 is already used. Also, I don't have bcmwl-kernel-source installed.
