This post will describe how to flash the Netgear WGT634u with OpenWrt using the Netgear web interface.  There are other ways to do it using a serial cable but this way is very easy and does not require you to build a serial cable.

Install Firmware Version

First we need to have firmware version installed on the WGT634u.  If it currently has version then you can upgrade directly to version  However, if you have a previous version then you need to upgrade to first.  For some reason upgrading directly to version from a version before causes an error.  To update the firmware log onto the WGT634u by visiting and username: admin, password: password.  If this does not work you may try resetting the router by pressing and holding the reset button until the lights go out.  Wait for them to turn green again before you try again.  Once you log onto the router then use the Netgear web interface to update the firmware.  Download the firmware at the following links:

Netgear Firmware

Update WGT634u Config File

Once the firmware version on the WGT634u is then you will need to upload a custom config file.  If the firmware version is not then the config file will not take when you try to upload it.  Download the special config file from the link below and upload it to the router using the “Backup Settings” option in the Netgear web interface.  Once you do that the router will reboot and and “Upgrade to OpenWrt” will appear as an option in the menu on the left.  Note: If you don’t see this option after you upload the config file then clear the cache.

Config File (firmware version

Upload OpenWrt Image to WGT634u

Once you have uploaded the custom config file to the WGT634u you will see an option in the menu on the left “Upgrade to OpenWrt“.  Use this function to upload the OpenWrt image to the WGT634u.  The process is similar to the process that was used to update the firmware image.  Once the image is uploaded and the router has rebooted then clear the browser cache and visit the web interface address again  You will be able to log into the web interface using the username root and a blank password.

OpenWrt Image 10.3:

Note: 10.3 is the latest stable version when this was written.  Note the path “brcm47xx”, use this to see what the latest version is.

Note:  Make sure that you clear the cache before visiting the web interface or it will tell you that it can not find the path.

Note:  Do not classify the router as dead until you give it plenty of time to reboot, rebooted it, and given it more time to reboot.

Note:  You will want to change the root password from blank if you will ssh into the router since it does not work with a blank password.


If all went well then you should be able to access the router using the default IP address and you will see the OpenWrt web administration interface.
