I have Windows Vista and it works fine.
One day my internet works but when i wake up the next morning my adapter connects to the router and says it's connected but when i run my browser(mozilla Firefox,Internet explorer)
it says:

The connection was reset
The connection to the server at %address was reset while the page was loading.

* The site could be temporarily unavailable or too busy. Try again in a few moments.
* If you are unable to load any addresses, check the computer's network connection.
* If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.
I've tried reinstalling my drivers and reset the adapter and getting new IP settings but nothing works.
I've also tried scaning my system for viruses and stuff using spybot search and destroy,Ad-Aware and norton anti-virus and theres still a problem.

Help plz.I'm on an older computer
