DSL-2750U/RA/U2EOL EOS
Wireless ADSL2+ Router with 3G/LTE/Ethernet WAN Support and USB Port
Description
USB Port
The router is equipped with a USB port for connecting a USB modem, which can be used to establish connection to the Internet. In addition, to the USB port of the router you can connect a USB storage device, which will be used as a network drive, or a printer.
ADSL Port and 4-port Switch, Ethernet WAN Support
The router is equipped with an ADSL port to connect to an ADSL line. The built-in 4-port switch enables you to connect Ethernet-enabled computers, game consoles, and other devices to your network. In addition, any Ethernet port of the device can be used to connect to a private Ethernet line.
Wireless Interface
You are able to quickly create a wireless network at home or in your office, which lets your relatives or employees connect to your wireless network 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.
The router supports multiple functions for the wireless interface: several security standards (WEP, WPA/WPA2), MAC address filtering, and the WPS function.
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.
Security
The wireless router DSL-2750Uincludes 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.
Easy configuration and update
You can configure the settings of the wireless router DSL-2750Uvia the user-friendly web-based interface (the interface is available in several languages).
Now you can simply update the firmware: the router itself finds approved firmware on D-Link update server and notifies when ready to install it.
