D6220 using as wifi extender
Hi, I've got a D6220 netgear wifi router, I'm having issues with BT fibre getting low upload and download speeds BT test showing 70mbs line speed mines dropping to 12, 15 etc so something isn't right with the router. I'm looking at going back to the BT hub 6 which i know holds the speed ok but wondering if the netgear D6220 can be moved to another location and used as wifi extender. I've tried it already using powerlines connected into the Red Wan port and port 1 and says no internet connection? do i need to change settings on the router to use the Wan or ethernet ports instead? Reason for re-using the router is because we have a system connected to it and needs to continue to speak to the router and the internet,
Any help would be appreciated.
