are there any yellow exclamation points? Mqybe some helper app missing from Sony ? Why the clean install of Windows ? What issues were you having prior to the clean install ?
I performed a clean install of Windows 7 64-bit on my Sony Vaio VPC-L231FX. I believe I installed all necessary drivers; the only ones I didn't install are some of the Vaio drivers for their photo viewer, media player, etc. I also currently do not have an anti-virus installed (besides Windows defender). The problem I'm having is the computer seems to gradually lose internet connectivity. When I reset my router, the internet seems to work great for a while. Eventually, however, the internet stops working despite the computer thinking it has a connection. I know its not a router problem since all of our other devices and computers continue to work well while this one is not. Any help would be greatly appreciated. Let me know if any more information is needed.
