Simultaneous Dual-Band
10/100/1000 LAN and WAN

The Mindspeed CPU is the main SoC for this device.

The RT3883 is apparently controlled via an MII interface (it's in iNIC mode).
The RT3593 appears to be controlled via the Comcerto's PCI bus.

The firmware provided by ZyXEL is ~14.5MB. The stock firmware is an OpenWrt-dervative firmware. The stock WebUI is a modified LuCI.

"45-402-000341" is silkscreened on the board shown below.

The default SSID for both bands is ZyXEL.

The power adapter included with the device is a DVE DSA-24CA-12 120200 (12V, 2A).

Addl. info[edit]

Telnet would seem to be enabled by default. Credentials of root:1234 for a router w/ default settings worked fine..
