Intel Wifi issues in 5.10

Hi,

I’m not sure where to report this.

I`ve been having some really bad wifi for a bit now. Some times the connection became incredibly slow, some times it was dropping all the time (and asking for the password - it was already filled, all I had to do is press enter).

Since today it was really bad, I went back to the 5.9 kernel. Seems like it is working fine.

My inxi -Fazy output is this:
