Section 1 - Product Overview
Introduction
The D-Link Wireless N750 Dual Band Gigabit Router (DIR-836L) comes equipped with 4 Gigabit ports to provide speeds up
to 10x faster than standard 10/100 ports. It also uses 802.11n technology with multiple intelligent antennas to maximize the
speed and range of your wireless signal to signicantly outperform 802.11g devices.
With the addition of Intelligent Quality of Service (QoS), data streams are separated which helps organize and prioritize your
network trac so your video streaming, gaming, and VoIP calls run smoother over both your wired and wireless network.
The D-Link Cloud Service will allow you to always have access to your home network no matter where you go. Now you can
monitor and manage your home network right from your laptop, iPhone®, iPad®7, or Android™ device. The cloud-enabled
router can be congured to send an email to keep you informed anywhere, anytime when new devices are connecting to
your network or unwanted access is detected. Monitor in real-time websites that are being visited with recent browser history
displayed on the mydlink™ Lite app – which is great for parents.
The D-Link Cloud Service can detect and block unwelcomed guests who try to get into your wireless network and suspicious
activities will be displayed right on your mydlink™ Lite app or browser.

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.
• 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 ISP to change connection
types (USB to Ethernet).
• 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.
• Several Internet providers (ISPs) such as Verizon and AT&T will supply you with a modem/router combo. Please verify
your modem is not also a router before installing. Connecting 2 routers together may not work correctly. If you do
have a modem/router combo, you must put your modem/router in Bridge mode to bypass the router functions
which will allow your DIR-836L router to work properly. Please contact your ISP or refer to your modem’s user guide
for more information.

Section 2 - Installation
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 in not
in use.

Section 2 - Installation
Note: It is strongly recommended to replace your existing router with the DIR-836L instead of using both. If your modem is a combo
router, you may want to contact your ISP or manufacturer’s user guide to put the router into Bridge mode, which will ‘turn o’ the
router (NAT) functions.
If you are connecting the DIR-836L to an existing router to use as a wireless access point and/or switch, you will have to do the
following to the DIR-836L 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://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. Note that a rst time setup will automatically launch
the D-Link Setup Wizard. If the wizard appears, click Cancel.
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

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 3 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 section for
more information on setting up your wireless network.
