hey, i'm a little new to this networking thing so i apologize ahead of time if i sound like a dummy.

i have comcast cable internet and the modem and router are hooked into my brother's computer, with a wire going into mine. i was pretty sure that we got the networking settings all figured out, and for some reason, my internet is working, but not his. which is weird because his internet has to be working for mine to work, right? i'm using a dynex dx-e401 4-port cable/dsl router.

anyway, any help would be greatly appreciated. thanks!

His does not have to be working for yours to work if you have what you described (router and not a hub). It should be set up like this:

The Comcast cable comes out of the wall and connects to the cable modem.
The cable modem connects to the router's "WAN" port.
Your two computers connect to the router.

Set it up like this and then turn everything off. Modem, router and PC's.
Turn on the modem and wait a couple of minutes. Not seconds. Minutes. :whistling:
Turn on the router and wait 2 minutes.
Turn on the PC's.

Post back with results.

BTW, if the router is a new addition, you need to call Comcast and let them know that you've installed it. They'll ask you for a MAC address. It's on a sticker on the router.
