I'm not sure why but when i look at my ipconfig in the cmd, it tells me:
Connectoin-Specific DNS Suffix: Private
This is a wireless connection. Is there any way to make it...err..not private?
I think it may be interfering with my connection on Xbox Live (I have the xbox connected to my pc via ethernet, and internet connection sharing switched on).
Bear in mind that this worked absolutely fine for me for about 10 months then decided to conk out on me and just plain stop working properly. Maybe this DNS thing is a problem? I'm clutching at straws here
