Modem's mac address through a router?

January 7, 2011 at 12:11:04
Specs: Windows 7 and Windows Vista on separate machines
I have a new router (ASUS RT-N10)and It is asking me to direct connect my cable modem to my computer, and then find my MAC address via command prompt, and clone it to the new router.

I can get to my command prompt, the problem lies in windows 7 and vista's (or mine) inability to realize that my network card is directly connecting to the modem. (No internet connection available, doesn't think anything is connected). I have tried on multiple machines to try and find my modem's mac address but it simply is not working.

I want to know if I can find the mac address through the old router, or what I need to do to have windows 7 recognize I'm directly connecting the modem to the PC.

(No internet connection available, doesn't think anything is connected).

Resolve this issue first. This could be a bad cable, or a NIC issue.

First, try another network cable. If that resolves the issue, you're done.

If it doesn't, then the problem may be the NIC. First, check in Device Manager, is there an exclamation beside the NIC? If there is then you have a hardware issue with the NIC. If there's not, then you may have a driver or TCP/IP stack issue.

Update the driver, if that doesn't fix the issue, try uninstalling, then reinstalling the TCP/IP stack. If that doesn't fix the issue, then you need to get someone competent to troubleshoot your PC.

It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.

And it is not your Modem's MAC address that is required. It is the MAC address of your computer's network card that might need to be cloned in the router in order for the modem to communicate with the router.

"It is asking me to direct connect my cable modem to my computer, and then find my MAC address via command prompt, and clone it to the new router."

A little confusion in this issue. You do not need to connect to the modem to get YOUR mac address. You simply to a cmd prompt and type ipconfig /all and note the Physical Address [same as mac].

I have never ever ever had to get the mac address of the modem [which usually isn't accessable by users usually to prevent them screwing things up from the ISPs point of view]

In turn you would enter this into the wan interface of the router.

The idea behind all of this is that the ISP registered one of your pcs/laptops originally mac address. Only that mac address is allowed access [which is why the win7 box isn't getting anything]

Not a bad idea to connect to the old router, go to its wan page and see what is listed for mac address.

Answers are only as good as the information you provide.
