Call COMCAST. They can trouble-shoot from "their" end,
if you tell them that none of your computers get an IP-address.

Also, plug _one_ computer _directly_ into the COMCAST modem.
Can you web-surf with that configuration?

What you're missing is that ALL the PCs will be connecting THROUGH the router to the Modem. Unplug the PC network Cable from the modem, then plug a network cable from the router's INTERNET port into the modem (where you removed the PC's network cable). Now, plug the PC's network cable into one of the ports on the router (usually 4 or more, marked 1,2,3,4. Think of a Router as a "splitter". It connects to the Modem, then several devices connect to the Router, some of them by wire and some by Wi-Fi. So your desktop PC is connected by wire to the router and your laptop PC is probably connected by Wi-Fi (wire is an option, as well). The Router sorts out all those signals and communicates with the Modem. Sound reasonable?

Check your ip settings in your pc and make sure they are set to get dynamically. Also check under wireless lan settings that you have dynamic ip turned on.

Otherwise you will manually have to set your computer ip address to the range set in the router/modem

I HAVE A NEW HP DESKTOP AND AN OLD LINKSSY WIRELESS G


Hi Vivian,

Chweck you cables and where they are conencted.

You will need to make sure that the Comcast modem is providing internet, you can do this by connecting your laptop to it using ethernet directly if it connects to the internet, that will be a good thing.

From your comcast Modem, the ethernet Cable should go to the linksys where it says "WAN". this should give you an internet connection and make your comcast modem communicate with your linksys Router.

Changed internet companies now router won't work


I'm sorry but I find your post a bit confusing. Do either of the computers get on the internet?
Changing internet providers is something done INSIDE the router. The cables are irrelevant.

A router is basically a mini-computer that splits up one internet connections to 4 (or whatever # of ports you have).

Basic Connections to a router:
A Router requires a internet connections, so your broadband modem must connect to the WAN port (theres only one) of the router DIRECTLY. Then Ethernet cables go from the router to the computers on the LAN ports. Don't do something weird like connecting your internet to your computer then your computer to the routers WAN port, it'll most likely mess up.

Once you have connected your router like this, it should work.

If your modem only has a usb port, I have no idea how to make that work out. Sorry. Try getting a new modem from your ISP, or check if your modem does have a ethernet port, if it does just connnect that to the routers wan port.

Also computers should not interconnect with each other with use of a router. Thats what the router is for. Everything gets connected and split up at the router, nothing connects to anything else but the router, basically.

Please help...internet won't connect


You may be running into a problem of your ISP only allowing one computer on the internet. while the internet is on can you access the internet from the desktop comcast originally setup?  If so that is more then likely your problem.

I have comcast myself and they told me they do not allow home networks. I fixed that problem by using the mac address cloning feature in my router.

The setup cd is also junk, all you should really need to do is:
1. unplug modem, router, and turn off computers
2. Plug modem into router
3. Plug computers into router (don't worry about wireless right now)
4. Turn on modem, wait 20 seconds or so for lights to set,
5. Turn on router. again wait for lights to set
6. Turn on ONE computer that is hard wired into the router
7 Try to surf the net.
8. If successfull try to connect wireless computers (Without using cd) and see if they surf.

If not call comcast and see if your computers are trying to obtain real-world ip's instead of LAN ip's like they should.
If so, you'll need to enable DHCP on the router.

How do i hook up a westell router to a moterola comcast modem?


Okay, well something is obviously wrong.
This is how it should be connected. Internet to modem, then with an Ethernet cable, connect the modem to the router (jack1) then with another Ethernet cable, connect the router (jack2) to the computer.
If you are still having problems, then contact your company to see if they could walk you through it, or if they needed to set things up.
Also, where are you connecting your laptop from? Is it very far from the router? Perhaps your router's signal strength isn't great enough? (This would mean getting a new, more powerful router.)
