Just a question, how do you know he has done the ping test wireless?
As to Ryan, speed should increase within a few days, it takes then about 2-3 days before they actually start the line testing, and quite quickly you should see speeds pick up.
My concern when going to Sky was to do with the ping, if they don't improve people keep mentioning a gaming profile which can improve this, from what I can gather though, it depends on your particular exchange as to whether this can be set or not.
You do realise their is a specific Sky section here that you can post to?
