Upgrading router but keeping sky q as modem?

[Gtiracer]

I thought this was possible but it seems I have read online that you cannot put the sky q router into modem only mode. Does this mean I can't use it with any upgraded router that isn't a modem/router combo?

Is this FTTC? You can get Openreach modems for a tenner or so on eBay, they are plug and play. Then you’ll need a router which supports DHCP option 61 IIRC for Sky and provide username/password.

Yes it is we've have a Netgear d7000 in place for the last 7 years or so but it keeps dropping the connection every half hour or an hour. Coule I use that in place of a modem then instead if that part isn't the faulty part of course?
