Hello

I have a AV600 Powerline plugged into a wall socket with an ethernet connection to my router.  This works well with the other 2 adaptors I use.  I have bought a AC750 mesh wifi extender to get the wifi to a distant part of the house.  I have tried to pair this with the AV600 using the WPS button on both devices but they will not pair.  I have rebooted the AC750 but still no pairing.  Any ideas of what is wrong / what I need to do?

Thanks
