This is a known issue and most likely you have one of the Sagemcom routers running firmware V202. If that is the case, you need the firmware downgraded to V174.
I have asked one of TalkTalk's support to pick your thread up and downgrade it for you.
They aim to respond within 48 hours (Monday - Friday) excluding Bank Holidays, but if more urgent you can always try the Service Centre on 0345 172 0088. The posts are responded to in time/date order, oldest first.
