Broadband cuts out when using Sky Sports HD channels

[dangle1979]

I changed the name of my broadband router today. Ever since, when I turn on any Sky Sports HD channel there is no signal, and the broadband turns off. 
All of the other channels work fine?

Are you a BT Broadband customer, if so, which BT Home Hub are you using?
