1 Introduction
Congratulations on your purchase of ESR1221N Wireless Network Broadband
Router. ESR1221N is compatible with 802.11b/g/n gadgets. ESR1221N is not
only a Wireless Access Point, but also doubles as a 4-port full-duplex Switch that
connects your wired-Ethernet devices together at incredible speeds.
At 150Mbps wireless transmission rate, Access Point built into the Router uses
advanced MIMO (Multi-Input, Multi-Output) technology to transmit multiple
steams of data in a single wireless channel giving you seamless access to
multimedia content. Robust RF signal travels farther, eliminates dead spots and
extends network range. For data protection and privacy, ESR1221N encodes all
wireless transmissions with WEP, WPA, and WPA2 encryption.
With inbuilt DHCP Server & powerful SPI firewall ESR1221N protects your
computers against intruders and most known Internet attacks but provides safe
VPN pass-through. With incredible speed and QoS function, ESR1221N is ideal
for media-centric applications like streaming video, gaming, and VoIP telephony
to run multiple media-intense data streams through the network at the same time,
with no degradation in performance.

6 ESR1221N Placement
You can place ESR1221N on a desk or other flat surface, or you can mount it on
a wall. For optimal performance, place your Wireless Broadband Router in the
center of your office (or your home) in a location that is away from any potential
source of interference, such as a metal wall or microwave oven. This location
must be close to a power connection and your ADSL/Cable modem. If the
antennas are not positioned correctly, performance loss can occur.
Wall Mounting
Screw Dimension: 18mm x 5mm
You can mount the device on the wall. There are two mounting points on the bottom
of the device. Please find a proper spot where two nails can be applied. Finally,
carefully mount the device onto the wall and make sure the nails are firmly locked on
the mount points.
