DD-WRT configuration

I was setting up my home network with two identical wireless routers. However, I was having issues getting everything to work properly. Consistently, one of the two wouldn’t work. Long story short – DD-WRT allows you to clone the MAC address via the web interface. However, it only alters the WAN and Wireless MAC and not the LAN MAC. The result is that all DD-WRT installs have the same LAN side MAC. This is only a problem if you have two routers running DD-WRT on the same LAN, which I did.

The only way to change the LAN side MAC Addr is to telnet to the router and change it via the shell. The following commands accomplish the task:

nvram set et0macaddr=xx:xx:xx:xx:xx:xx
