Looking for good inexpensive way the extend wifi to garage cam on BE30000

Probably all the cams in the house are 2.4ghz only. Occasional use when activated and not constant.

I have a RP-AX58 AiMesh node to my BE98 Pro.  It is inexpensive but my Rheem EcoNet water heater does not connect to it most of the time, (hardly anything ever does, they connect to further nodes preferentially).
