Router Troubles

My internet at my house isn't working, except on this computer. We have ethernet ports in every room and none of the ones we've tried (admittedly, not every one) work besides this one. So, this computer is connected by an ethernet cord right now, and to get the rest of the house to work I plugged in a router. So I took the cord from this computer (which I KNOW works, obviously, because I'm using it) and used that to connect the router. I plugged it into the "internet" slot, so that the other ones should be connected, and lo and behold, it doesn't work. We're utterly lost, our Comcast tech has come out twice and done absolutely nothing, and we really need help.

You have ports in all the rooms. Like wall ports, or plugs running from the router?
You plugged a working ethernet cable into the internet port of the router, ok am I right to assume that the other end of that port is going to your connection to the internet (broadband modem)?
When its working you have the ethernet from the broadband modem connected directly into your computer. You then took that ethernet cable out of the computer, and plugged it into the "internet" port on your router. Then took another ethernet cable and plugged one end into one of the numbered ports on the router, and the other end back into the computer, and it didn't work....?
Where do the "wall ports" come in? If someone wired your house with ethernet they should all converge at one spot, like a closet in the basement or something. The cables have to run to somewhere inside the walls. Where they all meet is where you want to have your router, each of those cables has to be a) terminated properly, as in, crimped for straight pair (not crossover) and b) plugged into one of the numbered ports on your router.
There are ALOT of points where this can possibly go wrong. Especially when you throw the wall ports into the mix. As an internet tech I've been on a DSL install to a doctor's brand new house, with wall ethernet ports in every room. None of them worked. I opened one up and the contractor never connected the CAT5 to the outlet, so it was just hanging in there inside the wall.

2. Unplug Modem
3. Disconnect all Ethernet cords
4. Connect Modem to Router via Ethernet Port labeled "Internet"
5. Connect Router to Computer via Ethernet Port labeled "1"
6. Plug-in Router, give it about a minute to boot up/warm up
7. Plug-in Modem, give it about 3-4 minutes to boot up/warm up
8. On Computer #1 goto the IP address in your browser to 192.168.1.1
9. Log into the Router/Server admin page: the typical username/pass is admin/admin
10. Make sure DHCP is turned on
11. Find the "Router Status" page and see if the Router's IP address is in the 192.0.0.0 range. If it is then your router hasn't detected the modem yet (which isn't uncommon). Click the DHCP Release button to zero out all of your vaules then click the DHCP Renew button a few times until new information comes up and the Router's IP address is something different.
12. Connect the rest of the computers.
Edit: Make sure the "Uplink" button on the router is NOT pushed in.

Also, in most Comcast markets, the modem absolutely needs to be powercycled or reset whenever you connect a new device to it. That could be throwing a wrench into your attempts as well.
Also, I just worked on a home network where the modem (DSL in this case) simply REFUSED to give an internet connection to more than one PC, even through a router on simple DHCP setup. In that case, I had to do this:
1. Get that one PC is working again.
2. write down it's given internal IP as well as the gateway and DSN address that it uses to talk to the modem.
3. Then take the PC's connection to the "internet" or "WAN" port on the router.
4. Plug the PC into a numbered port on the router.
5. Connect to the router's admin interface, follwing most of Magic Prime's instructions, but make sure it uses the same internal IP, gateway, and DSN as your PC does when it works.
6. Rather than depend on DHCP, hard-set the IP addresses on all your PC's, and make sure the Gateway and DSN's point to the Router, not the modem.
In the network I fixed, even after hooking up the router, the PC's on "automatic" would get valid addresses from the router, but still try to connect to the modem for gateway or DSN, which wasn't playing nice. By forcing them to go through the router, which then went through the modem, it fixed the problem.
Edit: Hm... I have two DNS's. What does that mean?
Most configurations should go Modem->Router->computers. Where do the wall ports run to? There has to be a router or hub or something on the other end of those wall ports, doesn't there?
So right now, when I put a cord straight from the modem (it isn't exactly one cord, because of the wall thing outlined in the picture, but effectively its one cord) into the computer, it works. But when you put a cord from the modem into the correct spot on the router, and then for example put the "kitchen" cord into the router, and plug your computer into the "kitchen" wall socket, it wont work. Theres a mixup somewhere in the router, and what I need help with is figuring out what that mixup is and how I can get rid of it.
When Comcast came out and set up your modem/internet, did they set it up on a PC connected to the modem through the router? Or did they set it up using a PC connected directly to the modem? If they did the latter, here's something you can try.
Hook the PC that Comcast used to set up your internet, to the router. Go into settings (192.168.1.1, or whatever they are if you're not using a Linksys). There should be a setting called "MAC Address Clone", or some variable of. Enable it, and clone the MAC address from the PC. Save the settings, reboot the modem and router, and see if that works.
