Revolutionary N+ Wireless Technology with MIMO (N MIMO)
Your Belkin N+ Wireless Router uses a new smart-antenna technology
called Multiple Input Multiple Output (MIMO). N MIMO complies with the
IEEE draft 802.11n specification. It increases speed, range, reliability,
and spectral efficiency for wireless networking systems.
The element that makes Belkin’s N MIMO technology different
from a conventional radio is the use of multiple antennas and two
simultaneous data streams to deliver wireless transfers around your
home or office. A conventional radio uses one antenna to transmit a
data stream. Belkin’s N MIMO, on the other hand, uses two antennas.
This design helps combat distortion and interference. Belkin’s N MIMO
is multidimensional. It builds on one-dimensional smart-antenna
technology by simultaneously transmitting two data streams through the
same channel, which increases wireless capacity.
Another element that enhances Belkin’s N MIMO is the use of
aggregation as specified in the draft 802.11n specification. By shortening
the space between packets and combining multiple smaller packets
into one larger packet, Belkin’s N MIMO can transmit more data through
available bandwidth.
Think of conventional radio transmission as a two-lane highway. The
speed limit governs the maximum allowable flow of traffic through
that lane. Compared with conventional radios, one-dimensional smart
antenna systems help move traffic through that lane faster and more
reliably—analogous to a four-lane road on which traffic consistently
moves at a rate closer to the speed limit. Belkin’s N MIMO helps
traffic move at the speed limit and opens more lanes—to become the
superhighway in this example. The rate of traffic flow is multiplied by the
number of lanes that are opened.

Placement of your N+ Wireless Router
Important Factors for Placement and Setup
Your wireless connection will be stronger the closer your computer is
to your Router. Typical indoor operating range for wireless devices is
between 100 and 200 feet.
In the same way, your wireless connection and performance will
degrade somewhat as the distance between your Router and connected
devices increases. This may or may not be noticeable to you. As you
move further from your Router, connection speed may decrease. Factors
that can weaken signals simply by getting in the way of your network’s
radio waves are metal appliances or obstructions, and walls.
If you have concerns about your network’s performance that might
be related to range or obstruction factors, try moving the computer to
a position between five and 10 feet from the Router in order to see if
distance is the problem. If difficulties persist even at close range, please
contact Belkin Technical Support.
Note: While some of the items listed below can affect network
performance, they will not prohibit your wireless network from
functioning; if you are concerned that your network is not operating at
its maximum effectiveness, this checklist may help.

1. Router Placement
Place your Router, the central connection point of your network, as
close as possible to the center of your wireless network devices.
To achieve the best wireless network coverage for your “wireless clients”
(i.e., computers enabled by Belkin Wireless Notebook Network Cards,
Wireless Desktop Network Cards, and Wireless USB Adapters):
• Ensure that your Router’s networking antennas are parallel to each
other, and are positioned vertically (toward the ceiling). If your
Router itself is positioned vertically, point the antennas as much as
possible in an upward direction.
• In multistory homes, place the Router on a floor that is as close
to the center of the home as possible. This may mean placing the
Router on an upper floor.
• Try not to place the Router near a cordless 2.4GHz phone.
2. Avoid Obstacles and Interference
Avoid placing your Router near devices that may emit radio “noise,”
such as microwave ovens. Dense objects that can inhibit wireless
communication include:
• Refrigerators
• Washers and/or dryers
• Metal cabinets
• Large aquariums
• Metallic-based, UV-tinted windows
N+ Wire less Router
If your wireless signal seems weak in some spots, make sure that
objects such as these are not blocking the signal’s path (between your
computers and Router).
3. Cordless Phones
If the performance of your wireless network is impaired after attending
to the above issues, and you have a cordless phone:
• Try moving cordless phones away from your Router and your
wireless-enabled computers.
• Unplug and remove the battery from any cordless phone that
operates on the 2.4GHz band (check manufacturer’s information). If
this fixes the problem, your phone may be interfering.
• If your phone supports channel selection, change the channel on
the phone to the farthest channel from your wireless network. For
example, change the phone to channel 1 and move your Router to
channel 11. See your phone’s user manual for detailed instructions.
• If necessary, consider switching to a 900MHz or 5GHz cordless
phone.

4. Choose the “Quietest” Channel for your Wireless Network
In locations where homes or offices are close together, such as
apartment buildings or office complexes, there may be wireless
networks nearby that can conflict with yours.
Use the Site Survey capabilities found in the Wireless Utility of your
wireless adapter to locate any other wireless networks that are available
(see your wireless adapter’s user manual), and move your Router and
computers to a channel as far away from other networks as possible.
• Experiment with more than one of the available channels, in
order to find the clearest connection and avoid interference from
neighboring cordless phones or other wireless devices.
• For Belkin wireless networking products, use the detailed Site
Survey and wireless channel information included with your
wireless network card. See your network card’s user guide for
more information.
These guidelines should allow you to cover the maximum possible area
with your Router. Should you need to cover an even wider area, we
suggest the Belkin Wireless Range Extender/Access Point.

5. Secure Connections, VPNs, and AOL
Secure connections typically require a user name and password, and
are used where security is important. Secure connections include:
• Virtual Private Network (VPN) connections, often used to connect
remotely to an office network
• The “Bring Your Own Access” program from America Online (AOL),
which lets you use AOL through broadband provided by another
cable or DSL service
• Most online banking websites
• Many commercial websites that require a user name and password
to access your account
Secure connections can be interrupted by a computer’s power
management setting, which causes it to “go to sleep.” The simplest
solution to avoid this is to simply reconnect by rerunning the VPN or
AOL software, or by re-logging into the secure website.
A second alternative is to change your computer’s power management
settings so it does not go to sleep; however, this may not be appropriate
for portable computers. To change your power management setting
under Windows, see the “Power Options” item in the Control Panel.
If you continue to have difficulty with Secure Connections, VPNs, and
AOL, please review the steps above to be sure you have addressed
these issues.
