@Ganger, if it's listed as one of these unsupported devices here:

....when you phone or Chat with an agent they should run checks and if there's a fault, they should replace it. If you renew a contract within 4 months of the end of your minimum term you can ask for a replacement with the new contract. If it's not actually faulty and you can't set up a new contract you'll be charged for a new router.

From the 29th of March our TalkTalk Community will move to peer-to-peer support and the TalkTalk team will no longer be here to support with queries. Don’t worry we still have plenty of ways to reach out if you need to speak to TalkTalk directly. For more details check out the link in the post at the top of any forum message board.
