Overview
C APTER 2. OVERVIEW
General Information
DSL-2750U is a multifunction LTE/3G/ADSL/Ethernet router with Wi-Fi and built-in switch The
router allows accessing the Internet via LTE or 3G GSM network (with a USB modem1 connected)
In addition, the device allows accessing the Internet via ADSL technology and via Ethernet
technology
The router is equipped with an ADSL port to connect to an ADSL line and 4 Ethernet ports to
connect workstations Due to this feature, DSL-2750U represents a moderate-priced solution for
creating wired networks without an additional switch In addition, any Ethernet port of the device
can be used to connect to a private Ethernet line Also the router has a USB port designed to connect
a USB modem, printer, or USB storage
DSL-2750U can operate as a base station for connecting wireless devices of the standards 802 11b,
802 11g, and 802 11n The router supports multiple functions for the wireless interface: several
security standards (WEP, WPA/WPA2), MAC address filtering, WPS, WMM
In addition, the device is equipped with a button for switching the Wi-Fi network off/on If needed,
for example, when you leave home, you can easily switch the router’s WLAN by pressing the
button, and devices connected to the LAN ports of the router will stay online
Support of guest Wi-Fi network allows you to create a separate wireless network with individual
security settings and maximum rate limitation 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 DSL-2750U 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 web sites for users of your LAN
Built-in Yandex DNS service protects against malicious and fraudulent web sites and helps to block
access to adult content on children's devices
You can configure and manage the settings of the multifunction wireless router DSL-2750U via the
user-friendly web-based interface (the interface is available in several languages)
The fast and easy configuration wizard allows you to specify all needed parameters in several
simple steps
You can simply update the firmware: the router itself finds approved firmware on D-Link update
server and notifies when ready to install it
