You are not speaking to Sky here.  It's a customer helps customer forum.

Have you ensured the router has any 'smart connect' functions disabled?

Is steering disabled?  (As a signal routed to 5GHz will drop)

I would recommend setting up two SSID's and ensuring the Q is connecting to the 2.4G band only.
