Turn on the router. The on/off switch is located next to the router's power input (labeled “Power On/Off”)
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.

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
The web interface of your router will appear. There is no password set at this point! The username is root
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)
There's a physical button to enable and disable the wireless which is not enabled by default and some additional software and configuration is needed as outlined below:
router$ opkg update
router$ opkg install wifitoggle
The configuration file is stored in /etc/config/wifitoggle
router$ edit /etc/config/wifitoggle
# Internal name of the button to use.

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. |
