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

network

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.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
