Welcome to Ask Ubuntu! Please add the output of `uname -r`. Is you system up to date? Run: `sudo apt update && sudo apt upgrade`. The wireless card should work with kernel 5.10+. Also, run `sudo apt install --install-recommends linux-generic-hwe-20.04`. Use [edit] to add additional info.

Please be precise with details; Ubuntu releases using the *year* format are different products to those using the *year.month* format, ie. 20 is a different system to 20.04. Which media did you use with 20.04? Was it an ISO using the GA kernel stack (5.4)? 20.04.2? (5.8)? 20.04.3 stack (5.11)? or 20.04.4 stack (5.13)? I'd try a different ISO with a later stack

Check what kernel runs in 21.10 and install that kernel in 20.04 LTS.

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.
