The Zyxel NBG5715 is a simultaneous dualband 802.11 abgn wireless router with gigabit switch and USB.

This router has a 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 not supported due to the lack of sourcecode for the Mindspeed CPU.

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).
