Section 1 - Product Overview
Introduction
The D-Link DIR-818LW Wireless AC750 Dual Band Gigabit Cloud Router provides revolutionary 802.11ac wireless speed - up to
750Mbps - for awless HD video streaming to multiple devices.
With mydlink™ Cloud Services, you can monitor your home network from anywhere, anytime, using your iPhone, iPad, and
Android device(s). Monitor what websites are being visited, block access from unwanted devices, and receive automatic e-mail
alerts when unauthorized connections are attempted.
With the mydlink SharePort™ app, you can wirelessly access your media that is stored on a connected USB drive from your
iPhone®, iPad®, or Android™ device. Best of all, you can get free apps for network management and le access.
* Maximum wireless signal rate derived from IEEE Standard 802.11ac (draft), 802.11a, 802.11g, and 802.11n specications. Actual data throughput will vary. Network conditions
and environmental factors, including volume of network trac, building materials and construction, and network overhead, lower actual data throughput rate. Environmental
conditions will adversely aect wireless signal range.

Section 2 - Installation
Before you Begin
Installation
This section will walk you through the installation process. Placement of the router is very important. Do not place the router
in an enclosed area such as a closet, cabinet, or in the attic or garage.
• Please congure the router with the computer that was last connected directly to your modem.
• Users with DSL providers - If you are using a PPPoE connection, you will need your PPPoE user name and password.
If you do not have this information, contact your Internet provider. Do not proceed until you have this information.
• Users with Cable providers - Make sure you unplug the power to your modem. In some cases, you may need to turn
it o for up to ve minutes.
•Advanced Users - If your ISP provided you with a modem/router combo, you will need to set it to“bridge”mode so
the DIR-818LW can work properly. For details, contact your ISP or refer to the user manual for your modem/router
device.

Wireless Installation Considerations
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, 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 (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 (.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 2.4GHz 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 2.4GHz 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.

Section 2 - Installation
Note: It is strongly recommended that you replace your existing router with the DIR-818LW instead of using both. If your modem is a
combo router, you may want to contact your ISP or review the manufacturer’s user guide so you can put the router into Bridge mode,
which will ‘turn o’ the router’s (NAT) functions.
If you are connecting the DIR-818LW router to an existing router to use as a wireless access point and/or switch, you will have
to do the following to the DIR-818LW before connecting it to your network:
• Disable UPnP™
• Disable DHCP
• Change the LAN IP address to an available address on your network. The LAN ports on the router cannot accept
a DHCP address from your other router.
To connect to another router, please follow the steps below:
1. Plug the power into the router. Connect one of your computers to the router (LAN port) using an Ethernet cable. Make sure
your IP address on the computer is 192.168.0.xxx (where xxx is between 2 and 254). Please see the Networking Basics
section for more information. If you need to change the settings, write down your existing settings before making any
changes. In most cases, your computer should be set to receive an IP address automatically in which case you will not have
to do anything to your computer.
2. Open a web browser, enter http://192.168.0.1 (or http://dlinkrouter.local./) and press Enter. When the login window
appears, set the user name to Admin and leave the password box empty. Click Log In to continue.
3. Click on Advanced and then click Advanced Network. Uncheck the Enable UPnP checkbox. Click Save Settings to continue.
4. Click Setup and then click Network Settings. Uncheck the Enable DHCP Server checkbox. Click Save Settings to continue.
Connect to an Existing Router

Section 2 - Installation
5. Under Router Settings, enter an available IP Address and the Subnet Mask of your network. Click Save Settings to save
your settings. Use this new IP address to access the conguration utility of the router in the future. Close the browser and
change your computer’s IP settings back to the original values as in Step 1.
6. Disconnect the Ethernet cable from the router and reconnect your computer to your network.
7. Connect an Ethernet cable in one of the LAN ports of the router and connect it to your other router. Do not plug anything
into the Internet (WAN) port of the D-Link router.
8. You may now use the other three LAN ports to connect other Ethernet devices and computers. To congure your wireless
network, open a web browser and enter the IP address you assigned to the router. Refer to the Conguration and Wireless
Security sections for more information on setting up your wireless network.
