@Gordon81 TP-Link do not support the main protocal Sky uses to authenticate its services which is DHCPv4 Option 61. You may be lucky and be able to connect using DHCPv6 PD which most but not all lines support (its down to the exchange equipment).
I use a Deco suystem myself set up in Access Point mode behind a Sky hub which gives me better wifi and no hassle. Some of theDeco's services like parental control don't work in Acess Point mode.
