I've been using XP on my Intel 2.0GHZ Core Duo for a while now, but one of my latest installs really killed the performance of the machine. Windows crashed quite a bit and Half Life 2 stuttered quite badly most of the time. I tried installing the Omega Drivers again, but this didn't solve anything. I formatted and reinstalled Windows. Now I cannot connect to my BT Home Hub at all! It says the signal strength is Very Good, but it has 'Limited or No Connectivity'. The WEP key is correct and I connect when booted in OSX. I've changed nothing in the install process... So I reinstalled Windows again - same problem, no connection! Any ideas?
