At my home, I have two computers networked using the Linksys router WITHOUT firewall (not sure of the model name/number). It was very easy to set up a long time ago, and when I recently moved and hooked my computer up at the new place, I simply had to plug in the router and it worked automatically. I am hooking up the Linksys BEFSR41 for someone else, and it is more difficult for some reason. It tells me that the network connection is up at 100mbps, but it will not let me connect to the internet. When I unplug the router and simply use the modem, it works fine. What am I forgetting to do, or what is going wrong?
