other people are reporting success on 21.04 ... it might be worth another go, with a fresh download? otherwise, "arch linux" might be your way to go for now?

This is due to no support for the AX210 wifi card in Ubuntu. When Lenovo was testing this laptop with, they used a specific oem kernel.

The solution is to install and then use this kernel on your computer instead of the one that comes with Ubuntu.

Kernel Version: 5.10.0-1022-oem

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.
