Overview
CHAPTER 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, 3G GSM or CDMA network (with a USB modem 1 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, 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.
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 websites for users of your LAN.
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).
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.
1 Not included in the delivery package. D-Link does not guarantee compatibility with all USB modems. Please, refer to the Supported USB Modems section, page 176.

DMZ
A DMZ is a host or network segment located “between” internal (local) and external (global) networks. In the router, the DMZ implements the capability to transfer a request coming to a port of the DSL router from the external network to a specified host of the internal network.
On the Firewall / DMZ page you can specify the IP address of the DMZ host.
Figure 103. The Firewall / DMZ page.
To enable the DMZ, select the Enabled checkbox, enter the IP address of a host from your network in the IP address field, and click the Apply button. To choose a device connected to the router's
LAN at the moment, select the relevant value from the drop-down list (the field will be filled in automatically).
Note that when the DMZ is enabled, all traffic coming to a port of the WAN interface of the router is directed to the same port of the specified IP address. Also note that virtual servers have higher priority than the DMZ host. In other words, if there has been created a virtual server that directs traffic from external port 80 to a port of the device from the router's local network, then entering http://router_WAN_IP in the address bar, users of the external network are directed to the specified port and IP address configured for the virtual server, but not to port 80 of the device with the IP address specified on the Firewall / DMZ page.
To disable the DMZ, deselect the Enabled checkbox and click the Apply button.

Safety Instructions
Place your router on a flat horizontal surface or mount the router on the wall (the mounting holes are located on the back panel of the device). Make sure that the router is provided with sufficient ventilation.
To prevent overheating, do not obstruct the ventilation openings of the router.
Plug the router into a surge protector to reduce the risk of damage from power surges and lightning strikes.
Operate the router only from an electrical outlet with the correct power source as indicated on the adapter.
Do not open the cover of the router. Otherwise any warranty will be invalidated.
Unplug the equipment before dusting and cleaning. Use a damp cloth to clean the equipment. Do not use liquid/aerosol cleaners or magnetic/static cleaning devices.

Wireless Installation Considerations
The DSL-2750U device lets you access your network using a wireless connection from virtually anywhere within the operating range of your wireless network. Keep in mind, however, that the number, thickness and location of walls, ceilings, or other objects that the wireless signals must pass through, may limit the range. Typical ranges vary depending on the types of materials and background RF noise in your home or office. To maximize your wireless range, follow the guidelines below.
1. Keep the number of walls and ceilings between the DSL-2750U device and other network devices to a minimum – each wall or ceiling can reduce your wireless network range by 3-
90 feet (1-30 meters).
2. Be aware of the direct line between network devices. Place your devices so that the signal travels straight through a wall or ceiling (instead of at an angle) for better reception.
3. Building materials make a difference. A solid metal door or aluminum studs may have a negative effect on your wireless range. Try to position your router, access points, and computers so that the signal passes through drywalls or open doorways. Materials and objects such as glass, steel, metal, walls with insulation, water (fish tanks), mirrors, file cabinets, brick, and concrete will degrade your wireless signal.
4. Keep your router away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that generate RF noise.
5. If you are using 2.4 GHz cordless phones or X-10 equipment (wireless devices such as ceiling fans, lights, and home security systems), your wireless connection may degrade dramatically or drop completely. Make sure your 2.4 GHz phone base is as far away from your wireless devices as possible. Note, that the base transmits a signal even if the phone in not in use.
