Just been reading these posts, as I have been having this since last Thursday too. I am with Virgin and live near Ebbw Vale Heads of the Valleys. I too have been through every possible solution that xbox live team could suggest and talked in length with my routers manufacturers.....tried a 2nd router too. But, after reading all these posts, I am glad I am not going off my 'rocker'......this has all been doing my head in, always thinking of different things I could try lol. Going to get onto Virgn and do a Victor Meldrew on 'em lol. I've been with them for 12 years, but I think it may be time to change.
