blogged a problem I was having with a friend's Sony Vaio Vista laptop and wireless randomly dropping. After some digging on the Sony site, I came up with this:

Knowledge Article C568483
The wireless network connection intermittently fails to connect.
When using the internal LAN-Express (Atheros) wireless network adapter to connect to a wireless network the following issues may occur:
* Not able to connect to a wireless network after a long period of usage or after resuming from suspend or hibernation.
* The LAN-Express wireless network adapter intermittently disappears from device manager or VAIO Smart Network.
* The wireless network connection intermittently fails to connect.
This issue is currently being investigated by Sony. Please contact the Customer Information Service Center at 888-476-6972 to speak with a customer service representative.
that's pretty much our issue in a nutshell. I guess it's good to know it's nothing we did wrong and there's nothing we could have done to fix it, but it sure is annoying still. Hope this helps someone else from going crazy trying to fix this.
