I have a BT WiFi disc, is it compatible with full fibre EE router? If yes, how can I connect it to the router?
Thanks
It depends on the router you have, if it's the one with 3 yellow and one red Ethernet cable (ee smart hub) then yes if it's the smart hub plus (this has an extra yellow Ethernet port) making 5 in total then no, also if you have one of the new pro hubs (they stand up like a tower block) it's a no.
Also to use the discs on your new package you need to have what EE are calling smart wifi.
As you got a new router your hub is likely not compatible.
