As a matter of interest do you supply any other router than the WiFi Hub?
I was supplied originally with a Sagecom model which was completely useless as it dropped connection randomly, this you replaced with another Sagecom which was the same and you finally changed this for a Huawei model which was much better but I still find that I can't watch Skysports as it stutters and pixelates and I have to reboot it so I have gone back to using the old DLink DSL-3782 which at least seems to have a good connection.
OK, well that clears that up. Is this the only notable issue you are experiencing with your broadband, is your service otherwise performing OK? If so would you like me to move this to the TalkTalk TV section so that the expert there can have a look for you?
