NO ONE LIKES THIS PROBLEM.
There is no absolute cures it every time cure but do your usual 6 MONTH CLEANING by short blasts of canned air (power off, no battery please) of the vents and hope that's enough.
I've started to use these 10 buck Wifi sticks to prove it's not the OS or drivers -> http://www.amazon.com/150mbps-Wifi-Wireless-Adapter-802-11b/dp/B0037G2BMY
This one is just too easy to install on Vista and 7. Just plug in and wait. Do not use the driver CD.
I've come seeking advice and aid for my laptop connection troubles. I'm probably not as well versed in tech support language as I could be, but I trust not the people of some general forum such as yahoo answers for help, as I fear most answers would suggest something along the lines of "check if ur cord is plugged in" or "refresh the web page". So i come to you, fine people of cnet.
Now, my problem is specific to my laptop (which is an Asus F50sf running vista if you care to know). My desktop and playstation 3, which are wired and wireless connections, respectively, both work fine.
My laptop works fine and dandy for about an hour, and then loses connectivity. Like I said, I am no computer Guru, and at first I figured it could have been my network adapter that was the problem, but if that were so, wouldn't I not be able to connect to my router at all? I can connect locally, but have no internet connection.
I've tried connecting via wired connection as well with no luck.
any advice or insight is greatly appreciated.
resetting the computer is the only thing that seems to fix the problem.
