My PC "Loses" Internet Broadband Connection

I've got a new HP Pavillion a500n PC running Win XP SP2, which is fully patched. I'm running Zone Alarm 5.5.062.011, Norton AV 2004, and Spybot S&D 1.3.1TX as a "security suite".

From time to time, this machine seems to "lose" its ability to utilize my broadband internet connection (Comcast cable modem service via a Netgear WGR614 v.3 wired/wireless router... this particular machine is connected via wired ethernet cable to the Netgear router). Usually, this happens when the computer sits unused for an unknown period of time... if I stay active on an internet connection, I don't seem to have a problem maintaining an internet connection. I have 2 other PCs (different makes/models) running WinXP SP2 also connected to the Netgear and I don't have problems maintaining internet connections.

When the PC "loses" its connection, I've tried using "ipconfig" which indicates that I still have an IP address. I haven't tried to ping anything as I'm not too familiar with that command. The only way I can seem to re-establish my internet connection is to reboot the computer.

Below is a log file from HiJackThis. I've also attached a zip file containing a Hardware inventory from Everest Home Edition (I hope this isn't too much information). Can anyone see anything that might be causing my internet connection to "die"?

Thanks in advance for any help you can provide in this matter.

Thanks;

I have the same problem as you do, only my provider is Charter. The problem only occurs if I leave the modem on for a couple of days without turning any of my computers on. It generally takes 20-30 mins. to correct, as I have to power down the modem and switch ( I don't use a router ) several times, and the problem corrects itself. Hope this helps!
