-Buffalo WZR-600DHP shares the same FCC ID FDI-09101889-0 with Buffalo WZR-HP-AG300H. This brings in a plausible hypothesis that in fact both models are identical except for their model number.  ​

-Indeed, WZR-600HDP is a replacement model for WZR-HP-AG300H,​ and their hardware look almost identical. However, the known procedure how to install OpenWRT for WZR-HP-AG300H does not work for WZR-600DHP. BuffaloTech is not responsive in assisting in regards to this matter. 
-===== Firmware ​===== +===== Installation ​===== 
-Buffalo provides two types of official firmwaresPro version and Friendly versionBoth are DD-WRT based, and downloadable from Buffalo ​tech's websiteDon't let naming fool you; Friendly version ​is not friendly in fact.+NoteIn OpenWRT versions prior to Barrier Breaker 14.07 there was no specific firmware for the WZR-600DHP but the same firmware as the [[toh/​buffalo/​wzr-hp-ag300h|Buffalo ​WZR-HP-AG300H]] could be utilized due to the similar hardware In this case after installation OpenWRT will report the device as the WZR-HP-AG300H even though it is the WZR-600DHP. In addition the factory image could not be flashed to OpenWRT through the standard OEM web interface firmware flash process because the firmware image was not specifically designed for the WZR-600DHP. Instead you needed to install the sysupgrade version using the wget and mtd commands through the OEM interface Administration -> Commands interface.
-In USA, Buffalo WZR-600DHP ​is shipped with its Pro version "​DD-WRT v2SP2-MULTI (11/0/12) std" (Filename: this router ​is individually supported since the Barrier Breaker 14.07 release it is suggested that you install that version as it will be much easier to install.
-==== Installation====+==== Firmware Download Quick Links ====
-The instructions provided below for C0B1 could possibly be outdated now. I was unsuccessful with that method ​after many attempts. The installation instructions for C0B2 (posted ​below) worked ​for my C0B1. Be patient, as it will take some time for the install to take. Do not unplug while the red light is flashing. I came from Buffalo'​s Pro Build (20180) using WinSCP to transfer the firmware.+Please consult the specific installation ​method below for each firmware ​type.
->> Some have reported failure with C0B1 using tftp method Be sure to follow ​tftp instructions to the letter, and it may take a few tries  because of timing Or try the C0B2 instructions as suggested above.+^ Firmware Type ^ Download Link ^

 +==== Installing using the Factory version using the OEM web interface ====
 +Since the Barrier Breaker 14.07 version of OpenWRT it is possible to install OpenWRT through the OEM web interface using the standard flash upgrade method in the web interface.
 +  - Download the openwrt-ar71xx-generic-wzr-600dhp-squashfs-factory.bin file to your PC
 +  - Load the OEM web interface (,​ admin/​password) from a DHCP configured computer
 +  - Click the Administration -> Firmware Upgrade tab
 +  - Click the browse button and find the openwrt-ar71xx-generic-wzr-600dhp-squashfs-factory.bin file on your PC
 +  - Allow the firmware upgrade a few minutes to complete. The router will reboot at least once.
 +  - Check your PC to see if the DHCP address of the PC has switched to the OpenWrt address of 192.168.1.x
 +  - Once your PC has a 192.168.1.x address you can load the OpenWrt web interface at and complete your configuration.
-//Confirmed working with router ​version ​C0B1, using openwrt-ar71xx-generic-wzr-hp-ag300h-squashfs-tftp.bin (Attitude Adjustment RC1)   ​(_john_i_ 2012-12-30)//​+==== Installing using the SysUpgrade ​version using the OEM web interface ====
-//Also confirmed working via sysupgrade ​on router version C0B1 using openwrt-ar71xx-generic-wzr-hp-ag300h-squashfs-sysupgrade.bin ​upgrading from 12.09-rc1 to 12.09 final (r36088) ​ (_john_i_ 2013-04-28) //+It is possible to easily install OpenWrt SysUpgrade versions using the OEM web interface (Buffalo branded DD-WRT) as long as you can connect the router to the Internet and do not use the firmware upgrade web utility. What you need to do is: 
 +  - Load the OEM web interface (,​ admin/password) from a DHCP configured computer 
 +  - Click the Administration -> Commands tab 
 +  - Enter the command "wget -P /tmp http://​​attitude_adjustment/​12.09/​ar71xx/​generic/​openwrt-ar71xx-generic-wzr-hp-ag300h-squashfs-sysupgrade.bin" and press the "run commands"​ button. This will download OpenWrt to the /tmp directory. 
 +  - Verify that the file downloaded by running the "ls -al /tmp" command. You should see the "openwrt-ar71xx-generic-wzr-hp-ag300h-squashfs-sysupgrade.bin" file listed in the directory contents. 
 +  ​Run the "mtd -r write /​tmp/​openwrt-ar71xx-generic-wzr-hp-ag300h-squashfs-sysupgrade.bin linux" command ​to flash the new firmwareThis will take a couple minutes to write to flash and automatically reboot. 
 +  ​- ​During the flashing process you will get some output to your web page including "​Unlocking linux ... Writing from /​tmp/​openwrt-ar71xx-generic-wzr-hp-ag300h-squashfs-sysupgrade.bin to linux ..." you will also see a solid red //"​DIAG"//​-LED 
 +  - Once the //"​DIAG"//​-LED begins flashing check your PC to see if the DHCP address of the PC has switched to the OpenWrt address of 192.168.1.x 
 +  - Once your PC has a 192.168.1.x address you can load the OpenWrt web interface and complete your configuration,​ when you load the page the first time the //"​DIAG"//​-LED should stop flashing and go out.
-If you read the following (previously posted) instructions,​ at least for version C0B1 there is no need to set the ubootenv accept_open_rt_fmt or (not mentioned, but like the WZR-HP-G300NH2 (version A1A0) (and not required for it either)) ubootenv tftp_wait. ​+==== Installation using the TFTP method ====
-This worked with Attitude Adjustment RC1 file  openwrt-ar71xx-generic-wzr-hp-ag300h-squashfs-tftp.bin (...-factory.bin filename typo fixed by OP, I quite possibly repeated the "go get some coffee..."​ step a few to many times??) I can now also confirm that at least the ...wzr-hp-ag300h-jffs2-tftp.bin works as well. Likely of small consolation to you but the reading is way easier than the writing... total chaos!!! ​+->  [[doc:​howto:​generic.flashing.tftp]]

-  - (Only tried this once to many and while possibly early on the timing it works every time.) Press enter to issue step 4's command (tftp) and then plug in the 600DHP. +
-  - Go get some coffee or tea while you wait for 5 minutes. +
-  - After no more flashing "​diag"​ light (which (at least on CBO1 model) is somewhat sporadic in its appearance),​ reset the IP on your machine to,​ and enter in your browser and proceed to configure. +
-  - NOTE ~ As of this writing step 6 configuration phase is largely (ok totally) untested by me 8-o hmm, hope it really all went to plan. +
-  - NOTE ~ Ignore previous note, no routers were harmed in the process, I repeat, no routers were harmed in the process. Configuration and operation work fine. I think I'm working towards creating some .bin files with proper 600DHP names, but it's hard to tell sometimes... to be certain, you'll know it when you see them.  +
-    +
-Because someone might get a laugh out of this, I should add that I had contacted Buffalo'​s tech dept. hoping for some help with the flash process before figuring it out myself. No, that's not the funny part. I noted in the inital message that I was willing to accept responsiblity for any damage incurred by my attempt. The replied I got back stated that the tech dept. couldn'​t assist in any potential warranty voiding procedures or activities. I responded by noting that although the point was probably moot, there was technically no voidable warranty on my router as I hadn't filed the paperwork. I gathered they weren'​t swayed at all by this fact as they neglected to respond.+

-  - Flash with Buffalo'​s ​Friendly version firmware +  ​* Pre-populate arp table on tftp'ing host, e.g.$ sudo arp - ​02:​aa:​bb:​cc:​dd:​20 
-  - Follow above link's procedure +  * The red //"​DIAG"​//-LED begins to flash rapidly when the router has received the image and is currently booting the new firmware
-  ​Go to​cgi-bin/cgi?​req=frm&​frm=py-db/55debug.html +  ​* Successful flashes via tftp using Windows 7 directly plugged into the router have been done.  ​It helps to add arp entries ​and disable media sensing as per the generic tftp instructions.

-//​Installation of Attitude Adjustment 12.09-rc1 on hardware version C0_B2 is confirmed but is quite difficult. The information below documents how it was done but may include extraneous steps and information.//​ +
- +
-  * Attempt at directly flashing openwrt-ar71xx-generic-wzr-hp-ag300h-squashfs-sysupgrade.bin through Buffalo'​s DD-WRT web interface fails. It looks like it will work but when the router finishes the reboot the DD-WRT system restarts. +
-  * Attempts to flash via TFTP failed, even after setting uboot environment variables "​accept_open_rt_fmt 1" and increasing tftp time with "​tftp_wait 6". These changes were made using the Administration -> Commands section of the Buffalo DD-WRT web interface. +
-  * Note: Changing the tftp_wait variable DID seem to make a change to the boot process, the router seemed to take longer to reboot but even after trying to increase all the way to 10 seconds I was not able to actually PUT the file via TFTP. By the time I was able to ping (even with a static arp entry) the DD-WRT system had already loaded and the TFTP window was closed. I'm not sure why the interface is not coming up and TFTP not working as it should, I do not have serial console access to watch the boot process. +

-In the end I was successful by enabling password based SSH access and using an SCP client to put the openwrt-ar71xx-generic-wzr-hp-ag300h-squashfs-sysupgrade.bin into the /tmp/root directory and then logging in with SSH and using **mtd -r write openwrt-ar71xx-generic-wzr-hp-ag300h-squashfs-sysupgrade.bin linux** to complete the upgrade.+
