Wife's Laptop Loses Internet Connection Repeatedly

My wife's Windows 8 Laptop loses internet connectivity frequently in our home. It still says connected and gives absolutely no indication that she has restricted or no access. She simply cannot access any kind of internet service.

I made sure that all of her drivers have been updated.
I changed the power settings so that the Wifi adapter cannot be shut off to save power.

We've had (have) up to 19 nodes connected to our Wifi router with absolutely no problems on any of them, including a Windows 7 and Windows Vista laptop. My wife's computer is the only one losing connection.

Hi, welcome to the forums, have a look in this thread and see if any of the suggestions help: http://www.eightforums.com/network-...tent-wifi-issues-super-frustrated-help-3.html
