Recently we got a new laptop and so also got a wireless router by Belkin its the Wireless G router model. Well we got it set up everything was working fine then the next day while on the Desktop it started logging me out of MSN which now wont send messages to contacts or send or recieve files bigger then about 500KB, also files cant be downloaded of internet. there are no problems with the laptop except at first wouldnt download files from the internet but it will now.

does anyone know why this might be, oh and by the way the desktop is running XP and the laptop is running Vista
