I am studying for Comptia Network+ and I am actually going to try to remember this for my test lol. I am still not up on 802.11 ax because I took the old retired A+ exam and they just covered up to 802.11ac.

You're doing better in certifications than I am!  I don't even have a CCNA, everything I know is just from me wanting to know.

Good luck!
