My brother is with Sky and he had to hack his Sky router to get the username and password from it but the connection keeps dropping out using the new (and old) router.under sky's terms and conditions you have to use their netgear router with their own firmware
I use a linksys router there is an unofficial forum that tells you how to get your username and password of the router so you can use a different router
not sure if I can post the link on there but a quick google search brings it up
