I have a AC1750 Mesh Extender. I recently replace my older router with a new one from Xfinity. Having trouble setting up/connecting to router. Tried using Nighthawk with no luck. Any suggestions? Jeff
Did you try using the installation assistant?
I'd factory reset the extender (push and hold reset for 7-15 seconds while powered on), then hardwire a pc/laptop into the extender (disable the pc/laptops wifi) and try setting it up using the installation assistant.
what xfinity router is it?
