Forget ringing talk talk help as you will be speaking to someone with a check list in India. The best thing to do is join the talktalk forum and post your issues there and one of the talktalk moderators will pick it up and deal with it properly for you, they answer posts from the oldest one first so might may be 24 hours or more before they answer but they have all the authority and equipment to do the tests from there end. Save yourself some time by first plugging the router directly into the master socket as that is the first thing they will ask - because they want to rule out any problems with your internal extensions ect, also try directly hard wired to the laptop from the router as they will ask if you are using wireless.
You will have to jump through all their hoops before they will contemplate a fault outside of your property
