Notes for TP-Link WR703N Mesh Test Firmware
-------------------------------------------

This alpha firmware was built by Elektra to test interoperability between the TP device and a Mesh Potato running SECN-1 firmware.

The firmware image is:
     openwrt-ar71xx-generic-tl-wr703n-v1-squashfs-factory.bin 

The firmware provides the XWRT web interface. The SECN interface may be added with a patch as shown below.

The BSSID of the MP devices used in a mesh with these TP devices must be changed to 02: ... to allow the devices to communicate correctly. 
This is due to a restriction on the allowable BSSID values by OpenWrt. Values must not have the least significant bit of the first field set to 1 ie only even numbers may be used. 
This firmware uses 02: as the first field.

The firmware *must* be loaded using the sysupgrade command line facility. 

A new TP device running the original firmware must be first flashed with one of the "factory" OpenWrt based images before any "sysupgrade" firmware can be loaded using the sysupgrade utility.

After flashing this software, there will be no led flashing activity to indicate the boot process. So give it several minutes to safely complete the flash process before power cycling the device.

The IP address of the device is 192.168.1.1    
Telnet to the device after flashing and set the root password. This will activate ssh for the next login.

The firmware includes a "run-once" script which requires that the device be restarted to complete the set up process.

After restarting allow several minutes for the device to be operating correctly.

The firmware also includes an open WiFi Access Point which is running by default, so take appropriate precautions to prevent inappropriate connections.

WiFi encryption can be enabled by adding two lines to the wireless config file as below:
config 'wifi-iface'
	option 'device' 'radio0'
	option 'network' 'wifi0'
	option 'mode' 'ap'
	option 'ssid' 'potato-AP'
	option 'sw_merge' '1'
	option 'hidden' '0'
# to add encryption
        option 'encryption' 'psk'
        option 'key' 'potato-potato'


The /etc/config/network file does not have an an entry for 'gateway' for the 'lan' section
To add gateway to allow internet access add the gateway definition line as shown:
config 'interface' 'lan'
        option 'proto' 'static'
        option 'ipaddr' '192.168.1.1'
        option 'netmask' '255.255.255.0'
        option 'type' 'bridge'
        option 'ifname' 'eth0 bat0 wlan0'
        option 'dns' '8.8.8.8'
# to add gateway
        option 'gateway' '192.168.1.254'
