These devices are preconfigured to act as an AP initially. Simply connect to its unencrypted network, and ssh to the device. The default root password seems to be p9z34c, admin or 1234. Once you've gained root shell access, edit /etc/config/network and /etc/config/wireless. You probably want the device to act as a client in your existing wifi network:

root@koven:~# cat /etc/config/network config interface 'loopback' option ifname 'lo' option proto 'static' option ipaddr '127.0.0.1' option netmask '255.0.0.0' config globals 'globals' option ula_prefix 'fd17:d40d:f634::/48' config interface 'lan' option ifname 'eth0' option type 'bridge' option proto 'static' option ipaddr '192.168.10.253' option netmask '255.255.255.0' option ip6assign '60' config interface 'wwan' option proto 'dhcp' root@koven:~# cat /etc/config/wireless config wifi-device radio0 option type mac80211 option channel 11 option hwmode 11ng option path 'platform/ar933x_wmac' option htmode HT20 list ht_capab SHORT-GI-20 list ht_capab SHORT-GI-40 list ht_capab RX-STBC1 list ht_capab DSSS_CCK-40 option disabled 0 option country CN config wifi-iface option device radio0 option network wwan option mode sta option ssid MyNetwork option encryption psk option key secretkey123


The stock firmware includes a couple of binaries (kkeps_*) that phone home to servers in China in order to offer cloud based access to the device through your smartphone. If you're keeping the stock firmware, consider disabling these in the startup scripts:

root@koven:~# cat /etc/rc.local
# Put your custom commands here that should be executed once
# the system init finished. By default this file does nothing.
#sleep 5
#/sbin/kkeps_on &
#/sbin/kkeps_off &
#/sbin/kkeps_seekwifi &
#/sbin/kkeps_reconect &

Flashing stock OpenWrt from the shell using sysupgrade works fine. I used openwrt-15.05.1-ar71xx-generic-tl-wr703n-v1-squashfs-sysupgrade.bin.

BEWARE, there are problems however:

  • The device has no ethernet port, so wireless must be enabled.
  • Stock openwrt firmware images has wireless disabled.

Theoretically sysupgrade -c should solve these problems, but for me 1 out of 3 Chaos Calmer upgrades failed to preserve /etc/config/wireless and all other changed config files, leaving the device unreachable.

You might want to play around with sysupgrade -l, -T or -i to make sure your config files is preserved during upgrade. Perhaps -b and -f is the safest way.

Another option would be to use the OpenWrt firmware image builder, and customize the image to include a wireless configuration that's enabled by default. See the comments in https://plus.google.com/116498915170668533255/posts/U4RhQYRShB6. Flashing this custom image would be safer with regards to misbehaving sysupgrade -c. Use -v with sysupgrade, since that will tell you which files will be preserved.

If the device has its wireless interface disabled, i.e. unreachable, you will have to pry open the case and solder cables to the serial headers on the pcb to fix it.

Stock firmware:

ON:
echo 1 > /sys/class/leds/tp-link:blue:relay/brigh­tness
OFF
echo 0 > /sys/class/leds/tp-link:blue:relay/brigh­tness

OpenWrt 15.05:

SETUP:
echo 26 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio26/direction
ON:
echo 1 > /sys/devices/virtual/gpio/gpio26/value
OFF:
echo 0 > /sys/devices/virtual/gpio/gpio26/value

For the stock firmware, you can configure the LEDs to act on certain events. Blink blue with network traffic:

uci set system.@led[0].name=wwan-link
uci set system.@led[0].trigger=netdev
uci set system.@led[0].dev=wlan0
uci set system.@led[0].mode='link tx rx'
uci commit system
/etc/init.d/led start

The relay is tied to the red LED, so setting the LED to default ON will make the relay ON after bootup:

uci set system.@led[1].default=1
uci commit system
