Asus ZenWifi XT9 - use Range Extender or Additional Node?

[CSnet]

Hi.

I have an asus zenwifi xt9 ax7800 with 2 nodes. The coverage in my house is not great upstairs and my external ring cameras often lose wifi. I need to extend the range to ensure y cameras get a good enough signal. Should I buy an additional XT9 node or buy a range extender (if so which one works best)?

Thanks

There are two ASUS range extenders RP-AX56 and RP-AX58.  The RP-AX58 works better, BUT I have them on Ethernet Backhaul.  I would not recommend either if you are going to add wirelessly.  I'd suggest getting another XT9 or oher ASUS router/ZenWiFi with better specs.
