Hi guys,

I often surf on line via WIFI. And it has been working well. While recently, I have upgraded the operating system of the laptop to Windows 8 beta. There is something wrong with the WIFI. Sometimes, when I click to enter some webpage, a box will pop up requiring me to enter the password to have access. While I have never encountered this situation when I use the ADSL.

Can you show me the reason and how to avoid it?

Many thanks!
