everything i have read about these units point me to the same thing as you have found: the only difference in these units is a name change, hardware wise they are the same as the wzr-hp-ag300h. i don't know of anyone that has one yet to confirm it, but pretty sure thats what is going on here.. _________________ Wireless N Config | Linking Routers | DD-WRT Wiki | DD-WRT Builds | Peacock - Broadcom FAQ
According to a post on the buffalo forum, it's a Japanese only model. Surprisingly new@@@ has it $20 cheaper than the ag300h.
It isn't a JP only model. Buffalo (USA) made a press release about them just two weeks ago:
Buffalo's AirStation HighPower N600 Gigabit Dual Band Wireless Router WZR-600DHP replaces the WZR-HP-AG300H...
brian_nathaniel (email@example.com) posted the following:
The WZR-600DHP has updated hardware chips and ships out with the revised/updated DD-WRT firmware. The WZR-600DHP is basically the next generation of the WZR-HP-AG300H.

Does anyone know if there are any (hardware?) differences between the Buffalo WZR-600DHP and WZR-HP-AG300H?
These two units seem similar enough that I successfully flashed the WZR-HP-AG300H firmware onto a WZR-600DHP.
At cursory glance, everything appears in order. No issues on the 2.4 GHz freq, and I don't have a 5 GHz client to test with. Both builds have almost the same web interface and capabilities.
Unrelated to the initial posting, but I'd been looking for a different version of firmware to run on the WZR-600DHP, as the VLAN options only included tagging, and I needed a more robust solution (5 WZR-600DHP units in current network project). If one could point me in the direction of downloading a MEGA dd-wrt version for either of these routers, I'd greatly appreciate it.
For reference - the web upgrade feature failed on a few different dd-wrt firmwares attempted (one from Buffalo, which has since been removed from their website). I'm not sure the distinction, but the "web upgrade" version worked:
I have the model WZR-600DHP japanese version.
To sucessfuly upgrade the firmware to english version of custom DD-WRT buffalo, i followed this steps in openwrt site:
1 - there is a way to set u-boot variables without serial access. Japanesse and other languages OAM "user frendly" firmware have special hidden maintenance page, accessible at http://your.router.ip.address/cgi-bin/cgi?req=frm&frm=py-db/55debug.html, with special username (bufpy) and password (otdpopy+<root password if any>) log-in required. Make sure you don't have the usual root athenticated WEB session active (clear the browser cache), otherwise you would receive an empty page saying "—- UNDER CONSTRUCTION — ". Now, one can activate telnetd by clicking the link, and access the OAM OS by telnet. Once there, one can use a command "ubootenv" to set above mentioned variables without trouble (tested & confirmed OK on Japanese WZR-600DHP)
2 - telnet to router and type:
ubootenv set accept_open_rt_fmt 1
3 - now, login to NORMAL webpage of the router but, this time, in username type bufpy and in password type otdpopy+<root password if any>
4 - look in advanced config tab and you will see links used by development team of buffalo japan. There is a NEW update firmware link. Use it to flash firmwares other than japanese protected firmwares.
I tested here and no problems so far.
Japanese WZR-600DHP --> DD-WRT Buffalo WZR-600DHP Sorry about my english. Hope this help someone.
I took a chance because I wanted to see if this method would work for using the WZR-600DHP firmware on the previous WZR-HP-AG300H. If it bricked, then it gave me a reason to switch to an updated router with the draft AC. I can confirm that the latest WZR-600DHP (Friendly Firmware) version 1.91 is operating on my WZR-HP-AG300H using the methods described in the previous post for accessing the developer firmware update page. The previous firmware I had installed was (Friendly Firmware) version 1.78, which was the latest available for the WZR-HP-AG300H before the product page was updated to the WZR-600DHP. Using the normal firmware update method through the admin router page would exit with an Invalid Firmware error. I have not noticed any problems with this firmware but I have not thoroughly tested it. I use my router for a static internet connection to a cable high speed provider, wireless access to multiple devices for networking and internet, streaming audio/video, connection to a Buffalo NAS, etc. Probably, most functions that people use their routers at home. The noticeable improvements were faster authentication/connection & longer range with my WiFi devices, no failures with automatic internet connection setup with my Cisco DOCSIS 3.0 modem (I don't have to setup manually), updated hyperlinks & help menus on the router access page, Movie Engine QOS improvements with lag... I cannot confirm if the DD-WRT firmware released for the WZR-600DHP could now be updated to this router because I don't plan on using it. However, I would gamble that it should since this version is working without any flaws for my network. I will not guarantee that this will work for everyone else. Try this firmware update method at your own risk.
