There is no such thing as access point mode, perhaps you mean bridge mode or even modem mode, neither of which are supported. Please explain in more detail how you are trying to use this router, presumably with some other router. Once I understand what you are trying to achieve, I will be able to help you.
The TalkTalk Community has now moved to a peer-to-peer support model. This means that the TalkTalk team will no longer be here to support with queries. Don’t worry, there are plenty of ways to reach out if you need to speak to TalkTalk directly. For more details check out the link here
