Weird Internet Issues

[PaulyWally]

Basic Etch system. Nothing too extravagant.

I think it's some sort of DNS issue. I can ping servers on the internet... I can download and install Debian updates... and I can even open up my router's control panel in a web browser. But I cannot open any internet pages in a web browser (tried Epiphany & Ice Weasel). Google.com, Yahoo.com, nothing works. Google was working briefly this afternoon. But I didn't change any settings that I know of.

I'm not sure where to look at this point. I checked all the network control panels in gnome. I checked to make sure the web browsers aren't looking for a proxy. Everything seems to check out.

The only thing I can say is... it worked perfectly until I tried to install a wireless network card a few months ago. I came close, but couldn't get it to work. So I wiped out the system, reinstalled etch from scratch (using the onboard lan) and I've had this problem ever since (with the wireless card sitting in a PCI slot). Perhaps just the existence of the wireless card is conflicting? In the network control panel, there is lo, eth0, and eth1. eth0 is disabled. eth1 in the onboard lan. And I physically removed the wireless card earlier today after running the DSL line to the room this computer is in.

Also, I am typing this up on this exact machine booted up to WinXP.

Any ideas where to look? Any help at all would be great! Thanks!

Could it be a firewall problem?

Edit your /etc/resolv.conf file and make sure you have a nameserver ip listed.

If you are using a router put in the default gateway ip for your nameserver. It will look something like this.

nameserver 192.168.1.1

You can also edit your router settings and see what your ISP is using for a nameserver, and put that in there. I would start with the default gateway though first.
