its knows that vista isfull of bags and corraps.
the fing is a computer with vista req a heavy vid card such as 9xxx (dont go on 8800 it is waste of money) and you need 2-4 gb ram for your computer to work perfect and so the best fing you can do try to download windows7 beta it is like windows vista but acts like xp wich is the best so look for a good downloadand goodluck.
First check in your router your wireless option WI-FI is enabled. Then check in laptop Wi fi driver are instaler and working properly. Also make sure your wi fi is enabled in network plces property and wi fi switch on laptop is turned on in laptop.
This is very common problem for the new computers, they can not be retro-fitted to XP for the drivers were not designed for XP, only vista.
I would strongly suggest putting the computer back to Vista, and then the hardware that was installed on that computer will work its best. Since Service Pack 1 has been released for Vista most of Vista's 1st problems have been solved.
