COMCAST data for a router.?

We have Comcast broadband cable service and are attempting to connect a Cisco Linksys Wireless "G" Router to provide internet service for a computer and a wireless laptop. Unexpectedly, the attempt by the so-called "expert" failed. He thinks he should have obtained a different router, but I think there is some data that is needed from Comcast to be added to the configsys file or some other esoteric file. What do you think?

    Connect the router to the modem, power cycle the modem, then power on the router. It should obtain an IP address from Comcast. If not, you may need to clone the computer's MAC to the router. Comcast server is looking for a specific device, with a specific MAC. If not found, or the MAC is different from the one Comcast has registered, you need to "fool" the server into thinking the computer is still the device connected. In the router setup, be sure DHCP is turned on, clone the MAC from the original computer, and power cycle the router again. It may take up to 5 minutes for the DHCP to renew the lease. If you still can't connect, call Comcast support, They can troubleshoot their side of the connection to be sure their server can "see" the router. It also wouldn't hurt to find out which DNS server IPs you should be using. The router should get those automatically, too, but it doesn't hurt to double-check.

    I had Comcast until I moved recently. At least then there was no special setup. What you need to do is make sure the modem that Comcast provides really works. Run the wire from the router to one computer. If you get on the internet ok go to the next step.

    Hook the wire from the modem to the WAN port of the router. Connect another wire between one of the router's LAN ports to one computer. From that computer you should be able to connect to the internet almost immediately. If not push the reset button with a paper clip. May have to hold it down 30 seconds. Then connect to the router's web page with numbers from your routers user guide, usually http://192.168.x.y/ Follow the user guide directions to set the SSID. Leave the password alone for awhile. With that you should be able to see the router with your wifi computer AND the wired computer.

    If that works go set up security if you wish.

    Still can't get on even with the wired computer? Call Linksys. You may have a dud.

    A Wireless Router should be able to obtain an IP address from your cable modem simply by being plugged into the modem. It will then provide IP addresses for all of the connected systems via DHCP.

    Make sure DHCP is Enabled, or just reset the router, as this will set it work with most standard configurations, at least for setup purposes.

    When you connect your modem to the router, reset the modem for a moment and then turn it back on.

    only time comcast would need to be involved is if it is a combination modem router. if it is just a standalone router then pretty much plug it in and go. other than setting up the wireless secuirty which is easy to do.

    i have comcast cable internet with all of my own equipment; motorolla sb5101 modem, linksys wrt310n router, linksys wrt150n router along with a linksys vonage adapter and a linksys hub

    once you place the port forwarding you may desire to maintain the settings, this could advise going to a distinctive element of the setup. additionally you may turn off dhcp on the router. exterior static ip's make no distinction on your use of the equipment.
