Nintendo Switch Connectivity Issue

So Xfinity asked me to upgrade my router, I’ve had the old one for a couple years, and I switched it out for a promise of higher speeds. Well since then, I decided today to use my Seitch for the first time in a while but it can’t detect my network anymore.

Any thoughts on what to do? I’m in the admin tool but I can’t change the security mode from WPA3 to WPA2 on any of the frequencies as they’re all greyed out.
