I’m not saying that your router sucks, I personally think that is pretty good router. I just think that it’s only a matter of a settings in the router, but then I might be wrong. I am a tinkerer and I don’t give up easily and I don’t like waisting money, so I always try to make things work for me.
There is a whole thread dedicated to Asus routers and Wyze camera compatibility, see below. Give some of those solutions a try. In any case, all the best to whatever you decide to do.
