I have a laptop and and a desktop. My sister has a laptop. Monday night all 3 were connecting to the home hub. Tuesday morning my laptop and desktop were connecting fine. My sisters laptop would not connect. it just said limited connection. the home hub is obviously working if it connects to both of mine. I have reinstalled the wireless driver and taken my sisters laptop to a friends house and it wont connect to there modem either. When my sister called Sony they did 5 minutes troubleshooting and then told her it was her internet provider. How can this be, and I think Sony just cant be bothered. So is there any thing any one else knows.
