IF the router is set up with DHCP, you *should* get an IP address.
Under Windows, from a command prompt run the command "ipconfig /all".
Under Linux, run the CLI command "ifconfig".  In either case, look for
your IP address, and the gateway IP address.  If both are set, try to
run a browser connecting to the gateway.

However, if DHCP has been disabled, or something strange is going
on, yes, you want a static address.  Most routers are either in the
192.168.1.0 or 192.168.0.0, with some (notably WatchGuard) different,
e.g., 192.168.111.0.

Look up your router either at the manufacturer's site, or on the
Internet.  If you can't find the doccos, try the followin static address
configurations:

  IP            Netmask       Gateway
  192.168.1.100 255.255.255.0 192.168.1.1
  192.168.1.100 255.255.255.0 192.168.1.254
  192.168.0.100 255.255.255.0 192.168.0.1 
  192.168.0.100 255.255.255.0 192.168.0.254

DNS typically won't matter for this.  For each, try connecting to the
gateway address with your browser.
