Section 2 - Installation
Before you Begin
• Placement of the router is very important. Do not place the router in an enclosed area such as a closet, cabinet, attic, or
garage.
• Congure the router with the computer that was last connected directly to your Internet connection. Verify that it is
connected to the Internet before connecting additional devices.
• If your ISP provided you with a modem/router combo, you will need to set it to“bridge”mode so the router can work
properly. Please contact your ISP or refer to the user manual for your modem/router device.
• You can only use the Ethernet port on your modem. If you were using the USB connection before using the router, then
you must turn o your modem, disconnect the USB cable and connect an Ethernet cable to the Internet port on the
router, and then turn the modem back on. In some cases, you may need to call your Internet Service Provider (ISP) to
change connection types (USB to Ethernet).
• If connecting to a DSL modem, make sure to have your DSL service information provided by your Internet Service
Provider handy. This information is likely to include your DSL account's Username and Password. Your ISP may also supply
you with additional WAN conguration settings which might be necessary to establish a connection.
• If you are connecting a considerable amount of networking equipment, it may be a good idea to take the time to label
each cable or take a picture of your existing setup before making any changes.
• If you have DSL and are connecting via PPPoE, make sure you disable or uninstall any PPPoE software such as WinPoET,
BroadJump, or EnterNet 300 from your computer or you will not be able to connect to the Internet.
This section will walk you through the installation of your DIR-1750.
Installation

7D-Link DIR-1750 User Manual
Section 2 - Installation
The D-Link wireless router lets you access your network using a wireless connection from virtually anywhere within the
operating range of your wireless network. Keep in mind 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 (radio frequency) noise in your home or business. The key to maximizing wireless range is to
follow these basic guidelines:
1. Keep the number of walls and ceilings between the D-Link router and other network devices to a minimum - each wall or
ceiling can reduce your adapter’s range from 3-90 feet (1-30 meters.) Position your devices so that the number of walls or
ceilings is minimized.
2. Be aware of the direct line between network devices. A wall that is 1.5 feet thick (0.5 meters), at a 45-degree angle
appears to be almost 3 feet (1 meter) thick. At a 2-degree angle it looks over 42 feet (14 meters) thick. Position devices so
that the signal will travel straight through a wall or ceiling (instead of at an angle) for better reception.
3. Building materials make a dierence. A solid metal door or aluminum studs may have a negative eect on range. Try
to position access points, wireless routers, and computers so that the signal passes through drywall or open doorways.
Materials and objects such as glass, steel, metal, walls with insulation, water (sh tanks), mirrors, le cabinets, brick, and
concrete will degrade your wireless signal.
4. Keep your product 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 (wireless products 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. The base transmits a signal even if the phone is not in use.
