Lose connection randomly, works after sleep

it is rare that my computer will be able to load pages with basic browsing for more than 10 minutes. After that it just stops and can't load anything. If I put the computer to sleep and then wake it up I will have another maybe 10 minutes before it will happen again. My connection to the airport shows a strong signal and the PC in the house has never lost connection. This has been a problem for only the past couple of weeks. I am worried that it is something with my computer and not with the connection. If that is the case then I am going to need some advice on what to check out or where to go to get info. Thanks for the help, I am pretty much paralyzed here.

i hate to say this but i am having similar issues. but unfortunately icannot help at this point. i am curious however to see what people have to say?
