Ok my Gentoo install went great and I have an IP address from my router BUT I can't ping anything outside my LAN. I know the problem is probably with the /etc/resolv.conf but I have NO IDEA how to fix it. Please advise. Thanks!

You can either use the nameserver provided by your ISP by adding

I am using a static IP addresss. So no dhcp.

I figured my problem was the resolv.conf but I had no way of figuring out the nameserver of the ISP because I am at my buddies house and don't have access to his router password -- which I thought would help me determine it.

I have never ran into this problem before so maybe his ISP act differently than mine. I have always just followed the Gentoo handbook and copied over the resolv.conf file during installation and everything was peachy...

So when I get home I will try your idea, but won't that be pointing to a name server in Europe? Or doesn't that matter too much since the internet is so quick now-a-days...

Since you're using a static IP I figure I should mention that you need to tell Gentoo where to route the packages to, too - so you'll need an entry in /etc/conf.d/net that matches your router:

put the
nameserver xxxx.xxxx.xxxx.xxxx

nameserver xxxx.xxxx.xxxx.xxxx
in /etc/resolv.conf

ok well none of that worked for some reason...
And I have another baffling discovery. I had been messing with the linux server trying to get access to the web when a few other people in the house started having network problems. They were running windows and they really didn't have anything to do with my problems.
Then I shut down the linux machine in question and they had their network to the outside world back in a few minutes.
What could be doing that?
The one hint is that they all could access LAN stuff no problem but none of them could get to the web and they couldn't ping anything outside the LAN.
Would the Gentoo box be trying to take over as the domain or name or dns server??
I have never had anything like this happen before so I am puzzled. More over I don't have anything but the basic installation from the Gentoo handbook installed on this system.
Any the linux system can't even get outside the network, but when that box is off everyone in the house doesn't have any problems...
Any ideas?

Yeah I had figured out that I had 192.168.2.1 set as my machine IP for some reason when it shouldn't have been... Sorry I didn't post the resolution of this problem. Actually I have many machines on the network that I port forward to for things such as ssh, mail server, web, etc. etc. but this stupid mistake cost me almost an hour of headache before I figured it out. And yes, DHCP is enabled for those wireless people (and machines running non-server systems) but I don't usually like to dynamically give out IPs obviously due to the dependence of the port forwarding.
