While connected wirelessly to any network, a couple of times a day or more the internet will all of sudden not work. It will stay I am connected, that there are no problems with connection, but no pages will load. It will say 'page not found' or whatever. Even if I disconnect/reconnect or reset the card, the problem will stay until I restart the computer and then it will work fine. I am on a Inspiron 1520 with a Intel wireless card and I have the latest drivers.
I would look for forms of interference in your home. The most common culprit is a 2.4MHz range cordless phone. Could be a neighbor's if not yours. I troubleshoot a lot of people's networks and have found interference to be the number one connection issue.
I downloaded a hot fix from microsoft that seems to be working so far (of course I still havent been to the network where it happensthe most). Anyways, in my apartment there are no phones like that or anything...it is pretty distinct because I can wait 10 hours when it stops working and it still wont work until I restart.
I cant remember the number of the hotfix, but after searching my internet history, this is the page I used to request it and they emailed it to me. If it doesnt work, I remember the hotfix said it has something to do with an error after you change internet permissions or something. So far no problems even with the network I usually had problems with,

Try opening the Intel ProSet Utility and setting the Power Management options to always supply full power.
