I just purchased the Powerline WPA8630 kit with 1 extender. Allows me to hardwire some devices in front room - well away from my router. Works brilliantly for ethernet. Wi-fi is a bit patchier and thus my query.
Prior to yesterday's purchase I was using a TP-Link RE450 wi-fi extender. I still have some downspots in the house and my query is: "Can I synch the RE450 up to the WPA extender or does it only synch with the router?"
