1INTRODUCTION
RG-5421G-Wac subscriber router (hereinafter the device) is designed for home users and corresponds to
unified access point to all interactive services trough wired and wireless commection channels. RG-5421G-Wac
is a development of RG-4402G-W subscriber router and has 4 Gigabit Ethernet ports, FXS port, WPS button and
button to enable/disable Wi-Fi. The device supports simultaneous operation in two Wi-Fi frequency ranges:
IEEE 802.11b/g/n 2.4 GHz and 802.11a/n/ac 5 GHz.
RG-5421G-Wac has extended functionality for stable delivery of IPTV via wireless network. Smothness
and steadiness of video playback are provided by special program functionality. The device allows you to
operate at 2.4 and 5 GHz frequencies and provides simultaneous broadcasting the video streams and data
transmission.
This operation manual describes intended use, main specification, rules of configuring, monitoring and
firmware update for RG-5400 subscriber routers.

2DEVICE DESCRIPTION
2.1 Purpose
RG-5400 is high-performance VoIP consumer router with the full set of options which allow consumers
to use TriplePlay advantages.
RG-5421G-Wac is a versatile wireless solution for home use. The device allows you to create LAN and
flexible to configure the home devices via Wi-Fi. WPS support allows you to simplify connection of large
numbers of devices (notebook computer, NV-501-Wac, will box, network printer) to RG-5421G-Wac. USB
connector is used to connect external drives or 3G/4G USB modem.
2.2 Design
The device is available in the following modification.

RG-5421G-Wac device has built-in Wi-Fi adapter with two indoor antennae. Built-in Wi-Fi adapter
supports 802.11ac technology, it allows you to provide data transmission service of the wireless network with
superior QoS in contrast with the device supported 802.11n. In addition, the device stays backward compatible
with the 802.11n, 802.11g and 802.11b devices. Besides of that, the device supports operation in two
frequency bands: 2.4 and 5 GHz.
