Hi is there a way to set up BT SH2 as a reapeeter/extender? My main router is Asus AX-RT86U. Got another PC on the other end of the house and is currently connected via power line using Ethernet cable. And don't know why speed is limited to 80/80 DL/UL
Not possible I'm afraid, you can use it as a wireless access point but you need to connect it to the main hub via Ethernet.
