internet connection keeps dropping.? when i connect wirelessly, most of the time (like 8/10 times) i cant connect to the internet. i use windows diagnostics and it says no problem found in internet connection. in network sharing panel, it says i am connected to the internet, it shows the router and all other device on the network, and that i am indeed connected to the internet. i used intel proset/wireless tool to diagnose, still no problems found, yet i still cant get to open any internet pages. its driving me crazy. i have no problems w/ internet if i use the cable ethernet, and my other laptops have no problem connecting wirelessly. just this vaio. restarting the latop would usually fix it, but i cant keep on restarting it everytime the connection drops. any ideas on why this is??? any input appreciated. thanks.
