Thanks for your post on our Community Forums and welcome back @Dawnburke!
Sorry to hear of the issues you're reporting to us, too work them both seperately;
Can you please confirm if you're able to log into your self-care account to see if there is an option to activate your Netflix account?
In relation to the issue with the broadband connection the set top box, we would be able to relocate either the set top box our router for a price of £25.00.
Alternatively, if you wanted to run an Ethernet cable from your router to the set top box, this may need to be purchased via a third party due the length required.
Kindest regards,
