My computer which is running Ubuntu 21.10 is not recognizing my wireless interface as shown by
$ ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
Though my hardware is at least recognized given this shortened output of lspci
$ lspci -v

Kernel modules: mt7921e
For my wireless card some people said they fixed the problem by upgrading their kernel to +5.12 but that did not work for me. As you can see I am running 5.13.
$ uname -a
Linux nick 5.13.0-20-generic #20-Ubuntu SMP Fri Oct 15 14:21:35 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
I also verified that the correct Kernel module is being loaded (mt7921e) and it indeed is
$ lsmod
