Antivirus update connection(no ping either)

[wchase73]

Here is the situation:
I have a DSL connection going to a Linksys wireless WRT54G. The main computer is wired to port 1, the laptop is wireless. All firewalls are turned off. From the main computer I can browse the internet and check email, but my Antivirus (avg & Avira) wouldn't connect to the internet for updates. I tried ping, nslookup, tracert from the main computer and none of them worked (request timed out). Everything works fine from the laptop.
Any ideas would be greatly appreciated.

Thanks for your help. I did uninstall both Ethernets and reinstall, and both won't work. I can use firefox and thunderbird with no problems. Here are the results you asked for: Also attached as word doc.

Just to recap.
My Setup; Linksys wireless router (WRT54G), Main computer wired to router, laptop wireless. Both running XP pro.
I can use web browser and email client.
I can not use any auto updates or anything that accesses a server (Antivirus update, wireless setup cd when it checks the internet)
I can not ping(or nslookup, tracert) anything outside my computer(Request timeout).
I can ping from within router and from laptop.
I have to Ethernet nics and have tried them both. (still no go)
I have tried direct connection to dsl modem. (still no go)
I can ping 127.0.0.1 so TCP/IP must be working.
I have no firewalls on the computer and the one in the router is disabled.
I only have AVG antivirus running.
I have unistalled and reinstalled both nics. (no luck)

You appear to have a firewall configuration issue. I can't think of any other reason you can't PING the default gateway of a standard router.

I apologize JohnWill. Many months ago I had Comodo pro installed on the computer. I had shut it down and disabled the service and subsequently forgot about it. This problem didn't occur until I uninstalled AVG 7.5 (which was installed before comodo) and installed AVG 8.0. Nothing was showing up in the task list. Well I ran Hijack and saw something that I thought was comodo. I uninstalled it and everything is good. I was really beating my head on this one. And I keep checking the firewall in the router and the windows firewall to make sure it wasn't on, the whole time forgeting about comodo. Anyhow I really appreciate your time and effort. I hope I can contribute back to the forums.
