using a mobile app. You can set up your router right from anywhere, no PC required.
The DIR-850L is also mydlink-enabled, which gives you access to your home network no matter where you are. Now you can
monitor and manage your home network right from your laptop, iPhone®, iPad®, or Android™ device. mydlink-enabled routers
can be congured to send an e-mail to keep you informed anywhere, anytime when new devices are connecting to your
network or unauthorized connections are attempted. Monitor websites that are being visited in real-time, with recent browser

* Maximum wireless signal rate derived from IEEE Standard 802.11ac, 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.
• 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 ISP (Internet Service Provider). Do not proceed until you have this
information. Also, make sure you disable or uninstall any PPPoE software such asWinPoET, BroadJump, or EnterNet
300 from your computer or you will not be able to connect to the Internet.
• 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-850L can work properly. For details, contact your ISP or refer to the user manual for your modem/router
device.

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 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.
