Linksys WRT54GS MAC Address difffers on unit than what is on screen????

Noticed the last number on the admin screen is different than what is on the bottom of the actual Linksys unit.


Guess it does not matter since I am using MAC filtering back to that box. Hope Range Repeater is the same..... Funny....

Anyone else see this on their router MAC address (underneath unit versus what is on admin screens)? Patty

It doesn't matter because the MAC addresses in question are the one's on your WRT54GS. You don't filter your own MAC addresses, just those of the connecting devices.

Your mysterious "range repeater" (whatever make and model that happens to be) *MIGHT* require a MAC address to operate, but more likely just requires the common SSID.

That's normal. The MAC address of the wireless and ethernet ports are usually different. Using DD-WRT on a WRT54G v3:

~ # ifconfig | grep HW br0 Link encap:Ethernet HWaddr 00:13:10:8C:14:A9 eth0 Link encap:Ethernet HWaddr 00:13:10:8C:14:A9 eth1 Link encap:Ethernet HWaddr 00:13:10:8C:14:AB vlan0 Link encap:Ethernet HWaddr 00:13:10:8C:14:A9 vlan1 Link encap:Ethernet HWaddr 00:13:10:8C:14:AA

What the various port names really mean:

Sorry. Made a mistake. The Linksys WRE54G range extender is the device that shows the LINK ID on its admin screen when the last digit does not match that of the WRT54GS.

So in other words the bottom of the WRT54GS has a mac address that lets say ends in 7.

The WRE54G Range Extender displays what I think is the ID of the WRT54GS router and its last digit is a "9".

Thanks, Patty

Yeah, that's normal. The ethernet ports have a different MAC address from the wireless port. I've never bothered to check if the MAC address on the serial number tag is that of the ethernet ports, or the wireless port.

Not a problem. If you're not sure which to use, just:

  1. Connect to the WRT54GS via wireless (without the WRE54G). Make sure your computer is NOT also connected via a wired ethernet connection.
  2. Open a DOS window and run: Start -> Run -> cmd arp -a

You should get a list of MAC address and IP address pairs. The one next to is your router's MAC address. For example.

arp -a Interface: on Interface 0x1000003 Internet Address Physical Address Type 00-0c-41-71-36-30 dynamic
