New customer, ethernet wall ports not working

[CamBand]

I recently switched from BT to Sky broadband. Within my household we have separate ethernet ports within the walls of each room to allow for wired connection. This worked fine with BT, however after switching to Sky they no longer seem to carry connection. How can I check if this is an issue with Openreach, which may require some sort of activation, or if it is faulty ports? Thanks, Cameron

Openreach has no involvement in local network cabling.

Is the Sky Hub in exactly the same position as that previously occupied by the BT Hub?

Is there a separate ethernet switch somewhere?

Its possible the Sky Hub is not negotiating ethernet properly for the wall ports. Have you tried changing the ethernet mode to 'Fast' on the Sky hub's admin settings?
