If you have a DSL plus a LAN, sometimes you can end up with one (or more) computers that can't connect to Quake servers.
The reason is that Quake tries to connect via the LAN, instead of the actually internet connection.
This usually happens particularly with DSL.
The "correct fix" is hard, basically the router should be set to authenticate PPPOE (you enter the DSL username and password in the router settings), but if you don't know how to do this, it sucks (calling your ISP and asking them to help you do this does work). The reason this solves the problem is that then the LAN *is* the internet connection.
The easier fix
1. Use the ProQuake Launcher and set the "Connect" button to "Connect: Internet IP" (should usually work)
2. Another solution, ...
If neither of the above work, it might be your firewall and if not call your ISP and ask them to walk you through setting up "your router to authentic via PPPOE" which simply means that the router will be programmed with the DSL username and password so the hardware is sharing the internet connection the proper way.

1. Click Start and then click Run and type "cmd"
2. In the black DOS screen, type ipconfig
You get something like this ...
Start Quake with -ip 192.168.1.100 or try with -ip 64.78.3.22, substituting those with the IP addresses that are displayed. Typically with DSL, it is going to be the IP address that does NOT start with 192.168.*.*

You get something like this ...
