The Vigor 2830n plus is Draytek's newest multi-wan xDSL router, supporting WAN connection via built-in ADSL2/2+ modem, Gigabit Ethernet or USB-connected 3G / 4G modem. Similar to Draytek's other lines, the 2830 comes in two other models; the 2830 without wireless and the 2830Vn plus with wireless and two FXS ports for VoIP telephony. Also in the 2830 product pipeline are the 2830n and 2830Vn, which are versions with single-band N radios, due out in June.
The 2830n plus is housed in a white plastic case that can sit on a desk or be wall-mounted using the slots on the bottom. Like the 2920, which was the last Draytek we reviewed, all ports and indicator lights are on the front of the device, shown in Figure 1.

Note that one non-lighted switch serves to both start a Wi-Fi Protected Setup (WPS) pushbutton session and turn on and off the radio. This isn't the greatest design, since it is easy to mis-time your button pushes and get an undesired result.
The back of the router has the power connector, power switch and three RP-SMA connectors for the supplied dual-band antennas.

Opening the 2830n plus case isn't too helpful for component identification since both the CPU and switch devices are covered with ceramic heat spreaders. So I asked Draytek for the component details. It turns out that the 2830n plus and 2920 are very similar designs, with the former using an Infineon Danube-S clocked at 333 MHz and the latter using a Danube clocked at 133 MHz.
RAM and flash complements are the same at 64 MB and 8 MB, respectively and both designs use an Atheros AR8316 Gigabit switch to provide the four LAN and one WAN ports.

The radio is an Alpha Networks WMP-ND02 mini PCI card, using a Ralink RT2880F MIMO Wireless AP/Router SoC for the BB/MAC and Ralink RT2850L 2.4 / 5 GHz 2T3R transceiver.
