Err, what do you expect to be changed?
Please can you elaborate by answering these few questions:-
1. What is your problem?
2. What make/model of router do you have (if this is a TalkTalk router, these details will be on a label on the rear or underside of it) and what firmware version is it running?
3. What is the exact status of the lights on the front of the router when this happens?
4. If you have any wired connections, are they affected in the same way as wireless ones?
