How do I set up a MAC Address on a Linksys Wireless Router?

I'm trying to find a way to setup a Wireless Lan in my house, but found out that Comcast Cable Internet restricts you to one MAC address per connection. So when I try to use the Internet with other machines than the first one I connected, it doesn't allow the connection to go thru. THen I learned that you can get around this by setting up a Router with a MAC address, and which fools the Comcast Internet connection to thinking its a single computer. Then somehow by cloning the MAC address - you can get other computers connected to the Router to share the Internet connection.

    There is less "fooling" involved than you may think.

    Routers always come with their own MAC address. This is the MAC address (and the *only* MAC address) which Comcast will see. All of the computers which you connect to the router (both wired and wireless) have their MACs hidden from Comcast. The router, true to its name, takes over the distribution of data between Comcast and all computers on your network.

    The only time you need to "clone" the MAC address on your router is if Comcast *already" has an authorized MAC for you. Which, in your case, they do--it is the MAC of the computer that you are currently using.

    You can either:


    1. Call Comcast and have them change the MAC address to that of your new router, or

    2. Tell the router to use the already-authorized MAC address from your computer. Comcast won't see the difference, and you are all set.
    Here are instructions for MAC cloning on the popular Linksys routers. It is very similar for other models as well.

Hello Jodu,

Please check the internet settings of the Lan connection in the Mac Book. May be there is IP Address or DNS settings is installed in your Mac Book which are stopping the wireless network services. Please check the IPV4 settings in the Lan or wireless connection properties.

I'm trying to set up a new laptop to my belkin router


When you first setup a wireless router you need to connect the wireless router to the computer with a LAN cable.
Then you open a browser such as Microsoft Internet Explorer and on the address bar you type the IP configuration address of the wireless router eg. for Belkin wireless router it is http://192.168.2.1
Enter the default login name and password.
You should change the password and you should setup WAP or WAP2 encryption (WAP2 is the strongest encryption) and change the SSID and turn off SSID broadcast.
For further wireless protection enable MAC address filtering. The MAC address of the wireless card is entered in the router MAC address filter table, which allows only the wireless card with this MAC address to connect to the router.
The wireless card on the computer needs to be configured with the wireless router's settings. The LAN cable can be removed and the computer communicates wirelessly with the router.

Then you open a browser such as Microsoft Internet Explorer and on the address bar you type the IP configuration address of the wireless router eg. http://192.168.0.1
Enter the default login name = admin and the password is left blank.

Trying to program my zonet zsr4154we with comcast modem cannot figure it out tried the sequence in the manual is there something else i must do also

To configure your router for Cable you will need to set your router's WAN (INTERNET) port to 'Dynamic IP' (DHCP) option. The router is set to this option by default.

Configuration steps:

Step 1 Connect the cable modem to the WAN (INTERNET) port of your router. If the modem has USB connection make sure that it is NOT connected to any computers via the USB cable and that the modem is switched to Ethernet (not USB). Only the modem's Ethernet port should be connected to the router's WAN (INTERNET) port.
Connect your computer(s) to the router's LAN port(s) or establish connection to it wirelessly.

Step 2 Open your Internet Explorer and log into your router by typing in its IP address (in most cases the default IP is http://192.168.0.1 ). Note that you do not have to be on the Internet in order to access this address because you are just connecting to your router's address. Specify username and password for your router, default is `admin' for both.

Step 3 After logging into the router select Setup. Set Internet Connection to 'Dynamic IP (DHCP)' option.
Setup'.

- Select the MAC Cloning option. Click on Clone MAC Address button. Do this from the computer which the cable modem was directly connected to the last time. This will place the MAC address of your computer into the router. Save settings and reboot the router. Reboot your cable modem as well.

- Log in to the router and go to Status page. Note what IP address it is getting on the WAN (INTERNET) interface. If the IP address you see under WAN (INTERNET) appears to be in the same range you are using on your network (e.g. 192.168.0.x), you will need to change the range you are using on your LAN to something different, e.g. 192.168.88.x. You can do this on your router under Setup > LAN Setup. Note that after changing the IP of your router you will only be able to access it through its new IP, e.g. 192.168.88.1.

- Uninstall your antivirus/firewall software (sometimes disabling or closing the software is not enough) and reboot your PC. After establishing the Internet connection through the router, reinstall your antivirus/firewall software.

Orange blink of death!!!


Hello houng_lee,

I have the exact same modem, if the modem/router light is blinking, that indicates a problem with the modem. You indicate that you have internet connectivety, so you should have modem light solid blue. When you look at the Wireless light it's probably off. Which means that at this point you have internet connectivety, you should put the cd in and run through the wireless connection wizard on the CD. It will check to see 1) if you have internet connection, 2) the type of connection you have (comcast) 3) if you have any wireless devices to be hooked up. 4) That all connections are working properly.

If you have a laptop that you want to connect to the wireless router, have it next to the router, so once you've finished setting up your Wireless security and issing a WEP number for local access, you can test your setting immediately with the Laptop. I always suggest that you create a WEP number for securty reason, If you perfer not to create a WEP number, and leave it as an open access (which is fine, and easier to setup) make sure that you shut off broadcasting, So your neigborhood doesn't jump online once they see an open access router.

If you've tried these steps let me know what problems your getting during the wizard setup. It will tell you if everything is setup correctly, or their is an error. Right now, I think the problem is your setup, and it's not communicating correctly. But, the wizard will tell you that as well.

Let me know,

Good Luck

Mark

> Your connection type should be Dynamic DHCP IP
> Click on "Clone your PC Mac Address"
> Click on save settings
> Go Status and Under WAN check if you have values in the IP address. If you have value, then that mean you have an Internet connection by now. if you got all 0.. try calling your Dlink manufacturer to assist you on conneting your router to the Internet without running the CD or by doing it manually in short..

Arimex comcast router won't talk to belkin wireless g plus mimo router


Comcast has a little known "trick" that they use when setting up users. Here's how it works:

When Comcast first comes to setup your new cable modem service, they insist on connecting it to your computer and "testing" it. Most people think nothing of it, and that it's good customer service ...truth be told, what they are doing is attaching your computer's MAC address to that cable modem, so that you cannot create a wireless network. This is because they want you to pay them $150 to do this for you.

In this situation, since the modem is a modem/wireless router in one, my guess is that the MAC address on your machine now does not match the MAC address on the new router, which is what Comcast has stored in their database(s).

Try this: on your computer (while connected to the modem), perform a release on your IP address (start, run, cmd, then type "ipconfig /release"). Disconnect the ethernet cable from the computer. Turn computer off completely. Hold down the reset button on the cable modem until it performs a reset. Once it's back up and running, boot up your computer with the cable back in the ethernet port.

The cable modem should assign a new address to your computer. However, that may or may not work ...this is an easy workaround with a Linksys router, but not necessarily with the all-in-one devices.

Worst case scenario: contact Comcast and notify them that the new modem is not recognizing your computer's MAC address and that it needs to be updated in their system. They will scan your computer (through the telnet interface on your modem) and get your computer's MAC address, then (hopefully) make the necessary changes on their end.

After that, everything should work flawlessly. If not, insist on a Comcast tech to "fix" the service that you are paying for.

Good luck - hope this helps :)
