MAC Address Clone
Clicking on the "MAC Address" tab (next to WAN IP Address) displays your
Router's MAC address, which is a 12-digit code assigned to a unique piece of
hardware for identification, like a social security number. Some ISPs require
that you register the MAC address of your network card/adapter connected to
your cable or DSL modem during installation. If your ISPs require MAC
address registration, find your adapter's MAC address by doing the following:
• If you are running Windows 98:
Click the Start button, select Run, type in "command," and press the
Enter key. At the DOS prompt, type "winipcfg."
• If you are running Windows 2000 or Millennium:
Click the Start button, select Run, type in "command," and press the
Enter key. At the DOS prompt, type "ipconfig/all." The "Physical
Address" with 12 digits is your Router's MAC address.
Enter those 12 digits into the fields below, and click the Apply button.
This "clones" your network adapter's MAC address onto your Router,
and prevents you from having to call your ISP to change the registered
MAC address to the Router's MAC address.

Troubleshooting

Common Problems and Solutions
This section provides possible solutions to problems regarding the installation
and operation of the Cable/DSL Router. Read below description to solve your
problems. If you can't find an answer here, check the Linksys website at
www.linksys.com.
1. I can't connect to the Cable/DSL Router.
• Check to see that the Cable/DSL Router is properly installed, the LAN
connections are OK (Link LEDs should be on), and it is powered ON.
• Make sure that your PC and the Router are on the same network segment.
If you are not sure, initiate the DHCP function and let the PC get the IP
address automatically.
• Make sure that your PC is using an IP address between 192.168.1.2 to
192.168.1.254 and thus compatible with the Cable/DSL Router default
IP address of 192.168.1.1.
• Also, the Subnet Mask must be set to 255.255.255.0 to match the
Cable/DSL Router's Subnet Mask. You can check these settings for the
Router by going to Start and Run, then type in "winipcfg" and press
Enter.
2. The Diag LED stays lit when it should not be lit.
• The Diag LED lights up when the Router is first powered up. Meantime,
the system will boot up itself and check for proper operation. After fin-
ishing the checking procedure, the LED turns off to show the system is
working fine. If the LED remains lit after this time, the device is not
working properly. Try to re-flash the firmware by assigning a static IP
address to the computer, then upgrade the firmware again. For example,
on one PC, use the following IP settings:
IP Adress: 192.168.1.50, Subnet: 255.255.255.0, Gateway: 192.168.1.1.
If that doesn't help, contact your dealer for more information.
3. I can't browse through the Cable/DSL Router.
• Check if both ends of the network cable and power adapter are properly
connected. Check if the status LEDs on the front panel are functioning
properly.
• If using Windows 95 or Windows 98, check the TCP/IP setup on the
client side. Run "winipcfg" by clicking on the Start button, then select-
ing Run. The PC should have an IP address of 192.168.1.xxx ("xxx" is
from 2 to 254.) Subnet Mask is 255.255.255.0, the default gateway IP
should be the Router's IP Address, and DNS (in "More".)
