====== ZyXEL NBG5715 ======

The [[http://www.zyxel.com/products_services/nbg5715.shtml?t=p|Zyxel NBG5715]] is a simultaneous dualband 802.11 abgn wireless router with gigabit switch and USB.

This router has a [[http://www.mindspeed.com/products/cpe-processors/comcertoreg-1000|Mindspeed Comcerto 1000]] (ARMv6) as main CPU combined 
with a Ralink RT3883 SoC which handles the dualband abgn wifi.

**The default firmware is a modified OpenWrt system based on a 2.6.35 kernel. The Web User Interface is likewise based on LuCI.**

The Zyxel NBG5715 is currently <color red>not supported</color> due to the <color red>lack of sourcecode for the Mindspeed CPU</color>. Nevertheless, it can be put to some (good) use by using the built-in OpenWrt (now ancient) firmware. See tips below.

===== Security =====

Telnet is by default enabled, and it is therefore highly recommended to login to the device via telnet and set the root password. Hereafter Telnet is disabled and ssh active (as with vanilla OpenWrt firmware).

===== Usage with built-in OpenWrt for (simple) scripting =====
When accessing the device using ssh, you have r/w access to the non-volatile mountpoint ''/jffs''. In factory default configuration, you have 1.7M free space. The mountpoint comprises ''/jffs/etc'' which also gives you access to ''/etc/rc.d''. You can also directly write to ''/etc/rc.d/'' and the content will end up in the jffs overlay file system and will be preserved across boots. To verify, one can to the following:

<code>
echo "date > /tmp/testlog.txt" > /jffs/etc/config/testscript.sh
chmod +x /jffs/etc/config/testscript.sh
ln -s /etc/config/testscript.sh /etc/rc.d/S98_testscript
</code>

Once the files are in place, check with the following if you get (volatile) output in ''/tmp/testlog.txt'':
<code>
/etc/rc.d/S98_testscript
echo /tmp/testlog.txt # should return the timestamp for the moment of execution
</code>

Then ''reboot'' the device and verify with ''echo /tmp/testlog.txt'' that you still get output in ''/tmp/testlog.txt''.
