After installation LEDE https://downloads.openwrt.org/releases/17.01.4/targets/ath25/generic/lede-17.01.4-ath25-ubnt2-squashfs-sysupgrade.bin. I used ssh to set the password and Luci to some network parameters, but after restart, all settings will be changed to factory settings LEDE. I do not understand. OpenWrt 15.05.1 version works well on this device.
