My warranty expires tomorrow, so I want to make sure this problem wouldn't be covered under warranty. Basically, my internet keeps dropping out. Most of the times is says "server not found." I then click "try again" and it will pull up the site. I have another HP notebook that I use with the same setup (router/modem) and it never drops out. Sometimes the internet drops out completely, and I have to try reconnecting numerous times to get it working. The odd thing is that it will still show the globe sometimes at the bottom and say I am still connected. Here is my setup:

-HP Pavillion 6000 notebook
-Intel Pro Wireless 3945abg
-Netgear Wireless router WGR614 Ver 6

The internet drops out at other locations as well. This coupled with the fact my other HP doesn't drop out at all leads me to believe that it has nothing to do with my ISP provider (I've tried other ISP's at a friend's house). I called HP support at he keeps saying it is my ISP provider. He also says it could be my antivirus settings. He then recommended I do a clean install and reload my operating system. I downloaded the latest drivers for the router and my network adaptor, but I guess I could check to see if I truly have the latest version.
