 With OpenWRT the default IP address of the router is 192.168.1.1. Connect to the router via Ethernet cable using telnet or web GUI. The router should now be configured to connect to the Internet. The following example supposes that the MR-3020 router is connected to a gateway configured with 192.168.1.1.

+===== Upgrading from a previous version =====
+If you are upgrading from a previous version of OpenWRT, you can follow this [[http://wiki.openwrt.org/doc/howto/generic.sysupgrade | tutorial]]. If something goes wrong, do not forget that a failsafe mode exists for the MR3020. Start by powering on the TL-MR3020. When the WPS Button starts to blink , push it until it blinks faster. The device is now in Failsafe-Mode. You may access it by using telnet 192.168.1.1. Then, clean up any installed packages:
+<code>
+root@OpenWrt:~# mount_root
+root@OpenWrt:~# firstboot
+</code>
 ====== Extroot configuration ======
+Start by removing the luci graphical interface in order to free some space for future package updates. Type the following command multiple times in order to remove all dependencies.
+<code>
+root@OpenWrt:~# opkg remove luci*
+</code>
 Update the packages and install the necessary tools to migrate rootfs on external storage
