@eb155 therexare potentially two methods of connecting a third party router directly to Sky full fibre connection. While the DHCPv4 Option61 works on all lines the simpler DHCPv6 PD method works on all City Fibre lines and over 80% od Openreach lines. Thexsecond method does nor requireca log-in string.
If that doesnt worl I believe your router support Open WRT which I think can be congigured to support Option61.
