4G LTE M2M Router with one module for two SIM cards


Built-in LTE Modem
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 50Mbps1
The router DWM-312 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 MAC filter rules and used to reboot the router at the specified time or every specified time period.
Easy configuration and update
You can configure the settings of the router DWM-312 via the user-friendly web-based interface (the interface is available in two languages – in Russian and in English).
You can simply update the firmware: the router itself finds approved firmware on D-Link update server and notifies when ready to install it.
