When I follow your instruction on page 1, I have the following:
LAN MAC: 00:1D:73:BA:EC:06
WAN MAC: 00:1D:73:BA:EA:07
Wireless MAC: 00:1D:73:BA:EB:08
I couldn't access the internet. Once I execute:
nvram set wan_hwaddr=00:1D:73:BA:EA:07
nvram commit
gpio disable 14
I get:
LAN MAC: 00:1D:73:11:11:12
WAN MAC: 00:1D:73:BA:EA:07
Wireless MAC: 00:1D:73:BA:EB:08
I can access the internet. With changed above and firmware 13637, I downloaded Office2007sp2 (247mb), Ubuntu(689mb), vista sp2 (480mb), and openOffice (138mb) without any issues. Thank you.
MAC cloning only works on wlan and wan, but there is no way to change the mac address on lan.
I find a simple one liner:
ifconfig br0 hw ether 00:1D:73:33:44:55
in the startup script seems to do the trick. The "nvram" commands change what's on the sys-info page, but don't change the "real" mac addresses on my WHR-G300N running dd-wrt ver 13972.

There is a RaLink Generic 3.3.0.0 firmware that can be flashed to the WHR-G300N
I flashed it to one of mine, and what do you know... SAME MAC address:
LAN MAC: 00:1D:73:11:11:12
I think what happened is Buffalo went Cheap and assigned the same MAC to all their routers.
It can't be just a DD-WRT bug if the same MAC shows up with generic RaLink firmware.
Guess we are just stuck with it. _________________ Soylent Green Is People ! =-=-=-=-=-=-=-=-=-=-=
2x Asus RT-N16 - Asus 3.0.0.4.354 Beta
Buffalo WZR-HP-G300NH V1 - OpenWRT 36542 Barrier Breaker
D-Link DIR-601 - OpenWRT 12.09 Attitude Adjustment
Linksys E3000 - Kong - 21395 - usb-ftp-samba3-dlna
Linksys WRT310N V1 - Brainslayer - 21286 - Std
Last time I checked the MAC addresses of one of the original WHR-G300N before I flashed it with dd-wrt, all wlan, wan, and lan had the same MAC address.
There were definitely not 00:1D:73:11:11:12, but the MAC address printed at the bottom of the device.

READ THIS SECTION ALSO!
The steps above do not always work on all WHR-G300N's
There is another way to fix this.
Goto the Main Setup tab, then the MAC Address Clone sub-tab.
Click the Enable radio button.
Fill in the Wireless MAC info as the SAME info from the Sys-Info page.
Don't change the Wireless MAC to a different value than what is shown on the Sys-Info page - its un-necessary!
You SHOULD change the WAN MAC address.
You should only have to change the last 3 hex values.
They can be whatever you want, leave the first 3 values alone.
Apply Settings and reboot.
This DOES work on 13525 and 136387!
I can confirm this info above, i have one DIR600B1 e one DIR300B1 and they only work in Repeater Mode with Virtual Interface added if i change the wireless mac of the routers in the Mac Address Clone tab.However i have 3 problems N mode is not working properly, i must use this ifconfig ra0 down in the administration->commands->save startup to disable the physical interface ( without this it will repeat 2 SSID's) the third problem is that we can not see any signal strength/quality from the main AP in the wireless status.I tested several builds and all of the them works in this way.right now i'm running r18000.
