I have news: I can connect to my 5 GHZ network now. I am not sure why though.
(1) I changed the 5GHZ channel
(2) I changed the frequency band from 80mhz to 40mhz
(3) Maybe the last driver update from March did something?

Here are my current outputs (I don't think there's much change though):

dmesg | grep 8821
