Setting up your router

Starting the router for the first time

  1. Connect the power adapter (12V) of the router to a power outlet and your router (labeled "Power 12V, 2.5A")
  2. Turn on the router. The on/off switch is located next to the router's power input (labeled "Power On/Off")
  3. The LED on the front of the router should start flashing. It may take a couple of minutes until the router completed booting, this is then indicated by a constantly lit power LED.

Accessing the LibreCMC web interface

  1. Connect your computer to your router via an Ethernet cable to one of the four Ethernet ports labeled in orange
  2. Your computer will now receive an IP address from your routers DHCP server (assuming your computer is set up to automatically connect to a DHCP server), this should only takes seconds
  3. Open a web-browser and enter the following address into the address bar: https://192.168.10.1/
    1. Another option is to enter the host name of the router instead: https://librecmc.lan
  4. If you're using a recent web browser, a "Your connection is not secure" windows will pop up because lack of the certificate chain to a "trusted authority" known by your web browser. You must create an exception in order to access the interface like so (example Firefox): Advanced -> Add Exception -> Confirm Security Exception
  5. The web interface of your router will appear. There is no password set at this point! The username is root
  6. After you've logged in it's time to change the password in order to improve security. This is the first task and very important, even more so as soon as there are untrusted devices or computers with e.g. an Apple or Microsoft operating system in your network. To change the password access the menu: System -> Administration and enter your new, secure password in the Password and Confirmation fields and click Save & Apply at the bottom of the page

Activating the wireless interfaces

The wireless interfaces need to be switched on manually (Menu: Network -> Wireless -> Enable)

Upgrading the router firmware (regular updates recommended)

It is highly recommended to keep track of distro updates. These often address critical security issues. Most distros have an RSS feed or mailing list for this which we recommend to monitor.

Upgrading the router firmware with a LibreCMC firmware binary

Do not disconnect your router from power while performing an update.
  • Visit the LibreCMC project's website
    • Download the latest firmware from the 'Main' section and select 'WNDR3800 Sysupgrade'
  • Login the routers web interface. If you haven't changed its network settings, the web interface can be reached at https://192.168.10.1
    • Select 'System' -> 'Backup/Flash Firmware'
    • Click on 'Browse' at the bottom of the page, select the firmware you've just downloaded and then push the 'Flash image' button.

The flashing process will take a couple of minutes, your router will come up again automatically once the upgrade is finished.
