i am having trouble going on many websites on my vista laptop at home. i have connected my laptop direct via a wire from the router and i have tried connecting via the wireless router and i am unable to access many websites. the only way in which i can access all sites is by connecting directly to the modem. our xp laptops are able to get fully working internet via the wireless and so is my iphone. i have tried many times to get the internet to work fully but have not been able to. help me please....
