Introduction
Placement of your Wireless G Router
Important Factors for Placement and Setup
Your wireless connection will be stronger the closer your computer
is to your Wireless Router or Access Point. Typical indoor operating
range for your 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 Wireless Router or Access
Point connected devices increases. This may or may not be noticeable
to you. As you move further from your Wireless Router or Access
Point, 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 ten feet from the Wireless Router or Access
Point, 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. Wireless Router or Access Point Placement
Place your Wireless Router or Access Point, 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 Wireless Router’s or Access Point’s
networking antennas are parallel to each other, and are
positioned vertically (toward the ceiling). If your Wireless
Router or Access Point itself is positioned vertically, point the
antennas a much as possible in an upward direction.
• In multistory homes, place the Wireless Router or Access
Point on a floor that is as close to the center of the home as
possible. This may mean placing the Wireless Router or Access
Point on an upper floor.
• Try not to place the Wireless Router or Access Point near a
cordless 2.4GHz phone.

2. Avoid Obstacles and Interference
Avoid placing your Wireless Router or Access Point 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
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 Wireless Router or Access Point)
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 Wireless Routers or
Access Points and your wireless-enabled computers
• Unplug and remove the battery from any cordless phone
that operate on the 2.4GHz band (check manufacturers
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 furthest channel from your
wireless network. For example, change the phone to channel 1
and move your Wireless Router or Access Point 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 LAN Utility
of your wireless adapter to locate any other wireless networks that
are available (see your wireless adapter’s manual), and move your
Wireless Router (or Access Point) and computers to a channel as
far away from other networks as possible.

54
Introduction
54
Introduction
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 in your
User Guide.
These guidelines should allow you to cover the maximum
possible area with your Wireless Router or Access Point. 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 are connections that 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 on-line banking websites
• Many commercial websites which require a username 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
re-running the VPN or AOL software, or by re-logging into
the secure web site.
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 Connection, VPNs and
AOL please review the steps above to be sure you have addressed
these issues.

bring you this unique feature. Your Belkin Wireless G Router is the first home
networking solution with an integrated web content filter that allows you to
block unwanted or offensive web content before it makes it to your network.
Unlike other Parental Control solutions, Parental Control is built into the Belkin
Wireless Router, so there is no software to install on any computer and you
will never be charged a per-computer fee for the service, ever. Your Wireless
Router comes with a six-month free trial of this feature so you can take
advantage of the capabilities right away. No credit card is needed to use the
trial. You have control: Belkin Parental Control can be modified to meet your
needs. You can set up your own policies and block any website you want.
There is also an optional reporting feature (fee-based) that allows you to get a
report showing you every website that was visited from your network (refer to
your Parental Control Manual for more information).
MAC Address Filtering
For added security, you can set up a list of MAC addresses (unique client
identifiers) that are allowed access to your network. Every computer has its
own MAC address. Simply enter these MAC addresses into a list using the
web-based user interface and you can control access to your network.
