-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 numer.   
-For FCC documentation, see [[https://fjallfoss.fcc.gov/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 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 firmwares: Pro version and Friendly version. Both 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: wzr600dhp-pro-v24sp2-20180-download.zip). +Currently there is no specific firmware for the WZR-600DHP.  Instead you use the same firmware as the [[toh/buffalo/wzr-hp-ag300h|Buffalo WZR-HP-AG300H]] which provides the same functionality due to the similar hardware. Note that after installation OpenWRT will report the device as the WZR-HP-AG300H even though it is the WZR-600DHP.
-==== Installation====+==== Firmware Download Quick Links ====
-//Confirmed working with router version C0B1, using openwrt-ar71xx-generic-wzr-hp-ag300h-squashfs-tftp.bin (Attitude Adjustment RC1)//+Please consult the specific installation method for which firmware you need to use.
-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. +^ Firmware Type ^ Download Link ^

 +| tftp | http://downloads.openwrt.org/attitude_adjustment/12.09/ar71xx/generic/openwrt-ar71xx-generic-wzr-hp-ag300h-squashfs-tftp.bin |
-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!!!  
-  - Pregame warmup ~ Give it a 30/30/30 +==== Installation using the OEM web interface ====
-  - Set ip of your box to +
-  - Issue arp command as follows: "arp -s 02:aa:bb:cc:dd:20" +
-  - On linux box type following command at la prompt: "tftp -m binary -c put name_of_firmware_file.bin" (windows users you'll have to make something up yourself) +
-  - (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. +
-  - Go get some coffee or tea while you wait for 5 minutes. +
-  - After no more flashing "diag" light, 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.  +
-Existing info... which might apply to some models?+Installation using the OEM web interface (DD-WRT v24SP2-MULTI (11/04/12) std - build 20180) does not work for the WZR-600DHP like it does for the [[toh/buffalo/wzr-hp-ag300h|Buffalo WZR-HP-AG300H]]. This is because there isn't a specific firmware build for the WZR-600DHP so the signature does not match what the OEM firmware expects. You must use alternative methods as provided below.
-Suggestions from [[http://wiki.openwrt.org/toh/buffalo/wzr-hp-g300h#locked.u-boot.too.short.time.tftp.window|here]] seems not working.  +It is possible to easily install OpenWrt 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: 
-At least, following method works in order to flash open source version DD-WRT from Buffalo's version DD-WRT. +  - Load the OEM web interface (, admin/password) from a DHCP configured computer 
-  - From Buffalo's Pro version firmware (stock) Web UI +  - Click the Administration -> Commands tab 
-  - Flash with Buffalo's Friendly version firmware +  - Enter the command "wget -P /tmp http://downloads.openwrt.org/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. 
-  - Follow above link's procedure:  +  - 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 to +  - 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. 
-  - Login with username "bufpy", password "otdpopy" + &lt;your password>;. By default <your password> will be "password+  - 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 
-  - Click "telnetd" and then "start"  +  - Once the //"DIAG&quot;//-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 
-  - telnet 192.168.11.+  - 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.
-  - type  +
-ubootenv set accept_open_rt_fmt 1  +
-reboot  +
-  - Go to http://192.168.11.+
-  - Login with username "bufpy", password "otdpopy" + &lt;your password>. By default <your password> will be "password" +
-  - Go to Adminstration _ .Firmware +
-  - Click newly shown link to install buffalo_to_ddwrt_webflash-MULTI.bin +
-It is unknown how to flash OpenWRT from this DD-WRT+==== Installation using the TFTP method ====
 +->  [[doc:howto:generic.flashing.tftp]]
 +=== Specific values you need ===
 +| Bootloader tftp server IPv4 address | |
 +| Bootloader MAC address (special) | 02:aa:bb:cc:dd:20 |
 +| Latest firmware tftp image | See Firmware Download Quick Links (**''NOTE:''** Name must contain //"tftp"//) |
 +| TFTP Transfer Window | 4 seconds |
 +| TFTP Window Start | approximately 10-20 seconds after power on |
 +| TFTP Client Required IP Address | |
 +=== Flashing Notes ===
 +  * Connect ethernet to one of the router's LAN ports
 +  * Configure tftp'ing host's ip address, e.g.: $ sudo ip addr add 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.
 +==== Installation using the remote shell method ====
 +It is possible to flash openwrt-ar71xx-generic-wzr-hp-ag300h-squashfs-sysupgrade.bin from the command line of a running DD-WRT, using the mtd command:
 +  - Shell into the command line, cd /tmp;
 +  - Copy the image file to /tmp by whatever means is handy (e.g. wget, scp)
 +  - mtd -r write openwrt-ar71xx-generic-wzr-hp-ag300h-squashfs-sysupgrade.bin linux
 +  - wait;
 +  - be happy.
 +Note from the boot messages that the linux partition starts at offset 0x60000 from the beginning of flash.  It would probably be wise to confirm that before proceeding.
 +==== Japanese version ====
 +On the Japanese version of Buffalo WZR-600DHP, you have first to change a setting on a hidden maintenance page.
 +  - Load the hidden maintenance page:, 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.
 +  - Run commands from text field:
 +    - 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 links, including one that will allow you to flash firware from any file you upload.
 +I 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.
-==== Flash Layout ====+From there, I was able to flash OpenWrt, following [[#installation.using.the.oem.web.interface|Installation using the OEM web interface]] above.
