transferred to EE set up ok but uses BT network and password does it matter

Not at all! EE has adopted BT's creds for its routers' PPPoE username and password.

@Chel5507 The EE Router can take and change the default's it has to match the existing as part of the setup process, just make sure that you keep a note off both that you are using now, especially if you have to return the BT router as you do not mention but looks like you have a new EE router in place. The only issue will be if you do have an EE router and are requested to or do a Factory reset then the values on the EE router card will take effect at that point.

The EE WiFi hub 7 just did everything and it’s great but just bothered as the details on the hub now uses previous details from BT hub

@Chel5507 As before, the EE Smarthub Pro if that is what you have for wifi7 on setup will take the BT ssid and it's password, change the Pro router with the details and give you virtually seamless connection with everything connected. The only issue is those details now do not match what you have on the EE Router card, so you HAVE to note what your BT ones where if you ever need to reset the router....
