-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.  ​ 
-For FCC documentation,​ see [[https://​​oetcf/​eas/​reports/​ViewExhibitReport.cfm?​mode=Exhibits&​RequestTimeout=500&​calledFromFrame=N&​application_id=369568&​fcc_id='​FDI-09101889-0'​|here]] 
-Indeed, ​WZR-600HDP is a replacement model for WZR-HP-AG300H, and their hardware ​look almost identicalHowever, 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.+===== Installation ===== 
 +Note: In 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.
-===== Firmware ===== +Because 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.
-Buffalo provides two types of official firmwares: Pro version and Friendly versionBoth are DD-WRT based, and downloadable from Buffalo tech's website. Don't let naming fool you; Friendly ​version ​is not friendly in fact.+
-In USA, Buffalo WZR-600DHP is shipped with its Pro version. ​ "​DD-WRT v2SP2-MULTI (11/0/12) std" (Filename: ​+==== Firmware Download Quick Links ====

-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+==== 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/​passwordfrom 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.
-This worked with Attitude Adjustment RC1 file  openwrt-ar71xx-generic-wzr-hp-ag300h-squashfs-factory.bin (*Note*: This may be error by OP.  I had to use the "​-tftp.bin"​ firmware rather than the "​-factory.bin"​ firmware), others are untested. Prob small consolation to you but the reading is way easier than the writing... total chaos!!! ​+==== Installing using the SysUpgrade version using the OEM web interface ====
-  ​Pregame warmup ~ Give it a 30/30/30 +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: 
-  - Set ip of your box to +  - Load the OEM web interface (, admin/​password) from a DHCP configured computer 
-  - Issue arp command as follows: "​arp ​-s 02:​aa:​bb:​cc:​dd:​20"​ +  - Click the Administration ​-> Commands tab 
-  - On linux box type following ​command ​at la prompt: ​"tftp -m binary 192.168.11.-c put name_of_firmware_file.bin" ​(windows users you'll have to make something up yourself) +  - 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. 
-  - (Only tried this once and) I think this is rather early on the timing, (but regardless) press enter to issue step 4'​s ​command ​(tftp) and then plug in the 600DHP+  - 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
-  - Go get some coffee or tea while you wait for 5 minutes. +  - Run the "mtd -r write /​tmp/​openwrt-ar71xx-generic-wzr-hp-ag300h-squashfs-sysupgrade.bin linux" command to flash the new firmware. This will take a couple ​minutes ​to write to flash and automatically reboot
-  - After no more flashing "diag" ​light, reset the IP on your machine ​to, and enter in your browser ​and proceed to configure. +  - 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 
-  - NOTE ~ As of this writing step 6 configuration ​phase is largely (ok totally) untested by me 8-o hmmhope it really all went to plan +  - 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.
 +  - 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.

 +  * Connect ethernet ​to one of the router'​s LAN ports 
 +  * Configure tftp'​ing host's ip address, e.g.: $ sudo ip addr add​24 dev eth0 
 +  * Pre-populate arp table on tftp'​ing host, e.g.: $ sudo arp -s 02:​aa:​bb:​cc:​dd:​20 
 +  * The red //"​DIAG"//​-LED begins to flash rapidly when the router has received the image and is currently booting the new firmware. 
 +  * 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. 
 +  * Flash should have reset all settings as well.  The IP address of the router should be now since is only for the bootloader at boot-time 
 +  * If your router has two red flashes of the DIAG LED followed by no flash and repeats then the flash failed or the image given is corrupt You can still recover with tftp.  Start over and try again.

 +On the Japanese version of Buffalo WZR-600DHP, you have first to change a setting on a hidden maintenance page.
-  ​* Attempt at directly flashing openwrt-ar71xx-generic-wzr-hp-ag300h-squashfs-sysupgrade.bin through Buffalo'​s DD-WRT web interface failsIt looks like it will work but when the router finishes the reboot the DD-WRT system restarts. +  - Load the hidden maintenance page:​cgi-bin/​cgi?​req=frm&​frm=py-db/55debug.html, username is **bufpy**, password is **otdpopy + <your admin password>​** (example: **otdpopypassword**). If you get a message ​"under construction", clear your browser cache (or open in private navigation) ​and retry. 
-  ​Attempts to flash via TFTP failedeven 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. +  ​Run commands from text field: 
-  * NoteChanging 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 TFTPBy 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 shouldI do not have serial console access ​to watch the boot process.+    ​ubootenv set accept_open_rt_fmt 1 
 +    - reboot 
 +  ​**''​NOTE:''​** you can also start tftp server if needed. 
 +  - Now clear your browser cache again, and open default web interface (, but this time using the credentials provided above (**bufpy**). 
 +  ​Go to Settings page (管理設定,​ //kanri settei// in Japanese), ​and you will see a few new linksincluding one that will allow you to flash firware from any file you upload.
-In the end 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.+didn't know which OpenWrt firmware file to use, but the original user who brought this procedure successfully flashed an DD-WRT firmware, so I did the same first.
-Note that OpenWRT is reporting ​the router as a "​Buffalo WZR-HP-AG300H"​ even though it is a WZR-600DHP.+From there, I was able to flash OpenWrt, following [[#​installation.using.the.oem.web.interface|Installation using the OEM web interface]] above.
