Please connect an Ethernet cable from your existing router/network in to the port labelled "Internet" on the back of the Buffalo.
Turn on the router and wait for a few minutes.
You will be prompted to log-in. The default username is "admin" and the password is "admin" (unless you have changed these).
Click "Administration" on the left menu
Click on "Firmware Upgrade" on the left menu.
If you receive an error message when trying to upgrade, that says the Upgrade Failed, please follow the steps below as an alternative method:
- Go to Services at the top then scroll down to SSH
- Click to Enable SSHd
- Click Save, then click apply at the bottom
- Finally, click Reboot
After the router has rebooted, you'll need to use an SSH client (i.e. putty or ssh command line). Connect to the router IP 192.168.11.1 and login with username root and your the same password you use for the web interface. Once logged in to SSH, run the following commands, one per line. Please ensure the router is connected to an Internet connection.
mtd -r write Buffalo_WZR-HP-G450H.bin linux
The router will now reboot and within a few minutes be back online with the new IP of 172.16.25.25.
