4G LTE Router
User Manual
Overview
CHAPTER 2.
OVERVIEW
General Information
The DWR-921 device is a wireless router supporting 3G/LTE with a built-in switch. It provides a
fast and simple way to create a wireless and wired network at home or in an office.
The router is equipped with a built-in LTE modem which provides 3G/4G mobile connection with
fast downlink speeds of up to 150Mbps and uplink speeds of up to 50Mbps.
You can use any Ethernet port of the router as LAN or WAN port. The new-generation firmware
supports assigning several WAN ports, for example, in order to configure the primary and backup
WAN connection of different ISPs. In addition, you can configure the WAN failover using the
built-in LTE modem.
Also you are able to connect the wireless router DWR-921 to a cable or DSL modem or to a private
Ethernet line and use a high-speed Internet connection to successfully fulfill a wide range of
professional tasks. The built-in 4-port switch enables you to connect Ethernet-enabled computers,
game consoles, and other devices to your network.
Using the DWR-921 device, you are able to quickly create a wireless network at home or in your
office, which lets computers and mobile devices access the Internet virtually anywhere (within the
operational range of your wireless network). The router can operate as a base station for connecting
wireless devices of the standards 802.11b, 802.11g, and 802.11n (at the wireless connection rate up
to 300Mbps).
The router supports multiple functions for the wireless interface: several security standards (WEP,
WPA/WPA2), MAC address filtering, WPS, WMM.
Support of guest Wi-Fi network allows you to create a separate wireless network with individual
security settings. Devices connected to the guest network will be able to access the Internet, but will
be isolated from the devices and resources of the router's LAN.
The wireless router DWR-921 includes a built-in firewall. The advanced security functions
minimize threats of hacker attacks, prevent unwanted intrusions to your network, and block access
to unwanted websites for users of your LAN.
The SSH protocol support provides more secure remote configuration and management of the
router due to encryption of all transmitted traffic, including passwords.
In addition, the router supports IPsec and allows to create secure VPN tunnels. Support of the
IKEv2 protocol allows to provide simplified message exchange and use asymmetric authentication
engine upon configuration of an IPsec tunnel.
The router also supports the SkyDNS web content filtering service, which provides more settings
and opportunities for safer Internet experience for home users of all ages and for professional
activities of corporate users.
Now the schedules are also implemented; they can be applied to the rules and settings of the
firewall and used to reboot the router at the specified time or every specified time period and to
enable/disable the wireless network and the Wi-Fi filter.
1 Data rates are theoretical. Data transfer rate depends on network capacity and signal strength.
