hi i have got sky broadband with there wireless router so far thats been ok the problem is that i have a toshiba satellite a30 and have just bought a belkin wireless g+usb adapter and installed it i have put in the key so it links to the sky router but it only connects for about 5 to 10 seconds then disconnects for the same again it just keeps doing this connecting and disconnecting for as long as i leave it on i have tried reinstalling it a few times but its always the same i also have tried out the adapter on my laptop at a friends house and it does the same on there sky router and i have tried the usb adapter on their laptop and it works fine so it seems to be something to do with my laptop i have tried sky tech but they could not help in any way on , is my laptop wasted or not thanks......... oh and im running it on windows xp home edtion
