In the context of your router, a MAC address (Media Access Control
address) is a unique identifier assigned by the manufacturer to each
network adapter in the piece of hardware. The first 3 octets (first 6
hex digits) identify the manufacturer. The rest of the MAC address is
used by the manufacturer for its own purposes.
http://en.wikipedia.org/wiki/MAC_address
In the case of the WRT54G, there are 3 network adapters:
1. The network adapter that connects the WRT54G to the cable or DSL
modem (aka the WAN or Internet port)
2. The network adapter that connects the WRT54G via a built-in 4-port
switch to your LAN via Ethernet (aka the LAN ports)
3. The network adapter that connects the WRT54G to your LAN via
wireless [aka the wireless access point]
Normally, each of the 3 MAC addresses should have the same first 6
digits. If you really copied the information in your post accurately,
you have an unusual WRT54G, because it indicates that the WAN adapter of
your Linksys WRT54G was manufactured by D-Link, while the other 2
adapters were manufactured by Cisco-Linksys. I also note that on my
WRT54G, the info you report is on sub-tabs of the "Status" page, and not
the "Administration" page; are you sure that you haven't mixed up two
different routers?
