FCC STATEMENT
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with the instructions,
may cause harmful interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one or more of the following
measures:
•Reorient or relocate the receiving antenna.
•Increase the separation between the equipment and receiver.
•Connect the equipment into an outlet on a circuit different from that to which the receiver
is connected.

Chapter 2 Hardware Installation
2.1 Before You Begin
Please read this User Guide carefully before installing and using the equipment. The operating
distance range of your wireless connection can vary significantly depending on the physical
position of the wireless devices. Factors that can weaken signals by getting in the way of your
network’s radio waves are metal appliances or obstructions, and walls. Typical ranges vary based
on the types of materials and background RF (radio frequency) noise in your home or office.
In order to optimize the performance of TL-WA850RE, please follow the instructions below to
achieve an ideal location (please make sure it is always within the wireless coverage of the
wireless router).
1) Half-way Between - Generally, the ideal location for TL-WA850RE is half-way between the
Wireless router and Wireless Client. If the wireless signal is not satisfactory, you may place
TL-WA850RE somewhat nearer to the Wireless router.
2) No Obstacles and Spacious - Clear obstacles in the way between TL-WA850RE and
Wireless router. It’s better to locate it in a spacious place, such as near the corridors.
3) No Interference - Keep TL-WA850RE far away from wireless interference, which may come
from electrical appliances that works in the same frequency band as TL-WA850RE, such as
Blue tooth devices, cordless phones, microwave ovens, etc.
4) 3 Signal Lights - You can also find an ideal location via the signal lights on the front panel of
TL-WA850RE. These lights show the strength of signal your range extender receives from
the root AP. It's recommended that you choose a location where at least 3 signal lights light
blue, in order to guarantee a good performance.

Note:
TP-LINK recommends that you connect to the Range Extender when your home network
connection is poor, or when you want a larger wireless coverage to eliminate “dead zones”. As in
compliance with the wireless transmission protocol, all the Range Extender devices are set to
work in half-duplex instead of full-duplex mode. In other words, the Range Extender has to
process one-way communication between your root Wireless router (or AP) and the terminal
clients; so the transmission time will be double-increased, while the speed will be decreased.
