Router Setup Problem

[Stephen]

What is the gateway for. Your network. Is it the router itself on .5? Or is
it on .1?

If dhcp is handing out .1 as its gateway and you assign .5 manually you
would have good internal connection but no route to the Internet.

A mouse trap, placed on top of your alarm clock, will prevent you from
rolling over and going back to sleep after you hit the snooze button.
