DD-WRT on Buffalo WZR-HP-G300NH

Installing DD-WRT

Installing using Linux (Ubuntu)

Original post by ERamseth. Read it here
Some commands and notes edited and optimized by Chalkos.

Setting Up

To do this you can use Ubuntu 9.04 Desktop Live CD

  1. Get the DD-WRT here (this is v24-sp2 (02/03/10) std - build 13832).
    You'll want the file ending in ".tftp"
  2. Get TFTP app
    1. On ubuntu enable Universe repositories
    2. Update repositories using
      sudo apt-get update
    3. Use
      sudo apt-get install tftp
  3. Do the Hard reset or 30/30/30 on your router.
  4. Unplug all ethernet cables and the power cable.
  5. Connect your computer through ethernet directly to your router but leave the router turned off.
  6. Disable NetworkManager. In Ubuntu 9.10, run
    sudo service networking stop
  7. Set IP of ethernet interface to "". In Ubuntu, run
    sudo ifconfig eth0
    (assuming eth0 is your ethernet interface)
  8. set netmask to "" I think this is default but just to be safe, run
    sudo ifconfig eth0 netmask
  9. Make entry in the ARP table corresponding to the router. run
    sudo arp -s [MAC ADDRESS OF ROUTER]
    • The MAC address of router is the SSID printed on the sticker, but every second digit/letter is followed by a ":", so you end up with something like "00:1D:73:8C:8D:D5" (THIS IS AN EXAMPLE DO NOT USE THIS NUMBER... I ACTUALLY JUST MADE IT UP)
    • what this really does is tell the network that (the IP address that the router will take for itself) corresponds with the MAC address of the router.
    • I'm not sure the arp table business is entirely necessary but it cannot hurt... also this is the one step i have absolutely no idea how to do in windows...

At this point you basically have a 1 computer network set up and your computer will be expecting the router (defined by its MAC address) to show up on (which is the address the router will ask for/respond on when it is turned on)

Uploading DD-WRT to the router

Important: Before starting TFTP navigate (on the shell) to the folder where you downloaded the firmware (otherwise you can not upload it using TFTP)

  • run tftp
    • Set verbose mode on (so we know what's going on);
    • Binary mode on (because we are uploading a binary file);
    • Trace on (so we get feedback on our commands);
    • Rexmt 1 (to retry the upload on failure every 1 second);
    • And timeout to 60 (repeatedly retry the upload for 60 seconds before giving up)

To do this on the regular tftp client, enter the following commands (in the text below, "tftp>" is just the prompt that tftp gives you, not something you need to type)

tftp> verbose
Verbose mode on.
tftp> binary
mode set to octet
tftp> trace
Packet tracing on.
tftp> rexmt 1
tftp> timeout 60
  1. in tftp connect to (does not matter that router is still turned off)
    tftp> connect
    • At this point you aren't really "connected" in the sense that your computer requires any feedback from the router. tftp is basically just prepped to send the correct file to the correct address, as long as all the other pieces of the equation (the router) end up in the right place at the right time.
    • now get ready to plug in your router, but don't do it yet. Also, make sure your computer is connected to one of the LAN ports of the router, not the WAN port (the WAN port is outlined in blue)
  2. In tftp put [firmware]
    tftp> put wzrg300nh-firmware.tftp
    • At this point tftp will keep trying to send the firmware to the router and when it fails (because the router isn't yet on or hasn't yet brought up it's tftp interface) it will wait 1 second and retry, up to 60 times (because that's how we set up the tftp client)
  3. Plug in the power cord to the router
    • The router will start up and now and you will see some lights blinking (possibly)
    • About 10-20 seconds in, you should notice that tftp is sending the file. instead of the retry message over and over you will see some progress scrolling down the screen and at the end it will tell you how many blocks or bytes were transferred in how many seconds
  4. After the transfer is complete, wait about 5-10 minutes (more like 6 minutes I think) during this wait the red light on front of the router will blink and then go off, eventually the wireless led comes on. (wireless led looks like a radar thing... don't know how to describe it really)
  5. When the wireless led is on, you are ready to go.

Final Notes
At this point, in linux, you want to just re-enable network manager with
sudo service networking start

You will see a notification icon that says you are connected. You should click it, disconnect, then re-connect. You should receieve an IP of something like
NOTE that this is not in the 192.168.11.X subnet. If you get something like or then something didn't work. Also, if you don't get an IP address assigned, something didn't work. As a last ditch effort, you could restart your computer to see if it works.

Also, per DD-WRT defaults, your router should now be broadcasting a WI-FI network on the SSID of "dd-wrt".

If you get an IP on the 192.168.1.X network, then congratulations, you are good to go. open up a web browser (see below) and get to to begin setting up your router.

NOTE: for some reason chrome/chromium isn't working on the web interface. I had to use firefox. Use Firefox for the web interface!
