As far as I’m aware, Cam v4 is the only Wyze Cam product[1] that supports Wi-Fi 6 (which is where WPA3 came into play, as I understand it). If you don’t have any other devices on your LAN that can use it, then disabling that might be worth a try. If it’s possible to disable it only on the 2.4 GHz band and have that band use only WPA2, then maybe that’s where I’d start.
This may or may not be relevant.
I’m not sure what @habib’s source is for that, but the discussion that follows in that topic might be interesting if not enlightening. He could be correct; I’m just somewhat skeptical of a lot of things without official sources, and even those can be wrong. This is what @grapefruityoda shared in that same topic:
Again, though, I’m just speculating about things that I might try in your situation. 
Their Mesh Router and Mesh Router Pro are also supposed to have Wi-Fi 6 support. ↩︎
