Wireless products are based on industry standards to provide easy-touse and compatible high-speed wireless connectivity within your home, business
or public access wireless networks.
wireless products will allow you
access to the data you want, when and where you want it. You will be able to
enjoy the freedom that wireless networking brings.
A WLAN is a cellular computer network that transmits and receives data with
radio signals instead of wires. WLANs are used increasingly in both home and
office environments, and public areas such as airports, coffee shops
and universities. Innovative ways to utilize WLAN technology are helping people to
work and communicate more efficiently. Increased mobility and the absence of
cabling and other fixed infrastructure have proven to be beneficial for many
users.
Wireless users can use the same applications they use on a wired network.
Wireless adapter cards used on laptop and desktop systems support the same
protocols as Ethernet adapter cards.

Wireless Basics (continued)
People use wireless LAN technology for many different purposes:
Mobility - Productivity increases when people have access to data in any
location within the operating range of the WLAN. Management decisions based
on real-time information can significantly improve worker efficiency.
Low Implementation Costs . WLANs are easy to set up, manage, change
and relocate. Networks that frequently change can benefit from WLANs ease
of implementation. WLANs can operate in locations where installation of wiring
may be impractical.
Installation and Network Expansion - Installing a WLAN system can be
fast and easy and can eliminate the need to pull cable through walls and ceilings.
Wireless technology allows the network to go where wires cannot go - even
outside the home or office.
Scalability . WLANs can be configured in a variety of topologies to meet the
needs of specific applications and installations. Configurations are easily
changed and range from peer-to-peer networks suitable for a small number of
users to larger infrastructure networks to accommodate hundreds or thousands
of users, depending on the number of wireless devices deployed.
Inexpensive Solution - Wireless network devices are as competitively
priced as conventional Ethernet network devices.
Standards-Based Technology
Based on the IEEE 802.11b standard, the GL2422MU-MT is interoperable with
existing compatible 2.4GHz wireless technology with data transfer speeds of
up to 22Mbps when used with other
devices.
Wireless Basics (continued)
Installation Considerations
The GL2422MU-MT lets you access your network, using a wireless
connection, from virtually anywhere within its operating range. Keep in mind,
however, 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:
Keep the antenna of the GL2422MU-MT in an upright position.
Keep the number of walls and ceilings between the GL2422MU-MT and other
network devices to a minimum - each wall or ceiling can reduce your DLink wireless product.s range from 3-90 feet (1-30 meters.) Position your
devices so that the number of walls or ceilings is minimized.
Be aware of the direct line between network devices. A wall that is 1.5 feet
thick (.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.
Keep your product away (at least 3-6 feet or 1-2 meters) from electrical
devices or appliances that generate extreme RF noise.
Building Materials can impede the wireless signal - a solid metal door or
aluminum studs may have a negative effect on range. Try to position wireless
devices and computers with wireless adapters so that the signal passes
through drywall or open doorways and not other materials.
Getting Started
With its default settings, the GL2422MU-MT will connect with other
products, right out of the box.
A wireless broadband RouterGL2422RT
A laptop computer with a USB wireless network adapter GL2422MU-MT
A desktop computer with a USB wireless network adapter GL2422MU-MT
A Cable modem There are basically two modes of networking:
Infrastructure . using an Access Point or Router, such as the DI-614+.
Ad-Hoc . directly connecting to another computer, for peer-to-peer
communication, using wireless network adapters on each computer, such
as two or more GL2422MU-MT wireless USB adapters.
On the following pages we will show you an example of an Infrastructure
Network and an Ad-Hoc Network.
An Infrastructure network contains an Access Point or Router. The
Infrastructure Network example shown on the following page contains the
following network devices (your existing network may be comprised
of other devices):
You will need broadband Internet access (a Cable or DSL-subscriber line into
your home or office)
Consult with your Cable or DSL provider for proper installation of the modem
Connect the Cable or DSL modem to your broadband router (see the Quick
Installation Guide included with your router.)
Install the DWL-120 wireless USB adapter into an available USB
port on your desktop computer. (See the Quick Installation Guide included with
the GL2422MU-MT.)

2. What variables may cause my wireless products to lose reception?
products let you access your network from virtually anywhere you want.
However, the positioning of the products within your environment will affect the
wireless range. Please refer to Installation Considerations in the Wireless
Basics section of this manual for further information about the most advanta-
geous placement of your wireless products.
3. Why does my wireless connection keep dropping?
4. Why can.t I get a wireless connection?
If you have enabled Encryption on the GL2422MU-MT, you must also enable encryption on all wireless devices in the network in order to establish a wireless
connection.
Antenna Orientation- Try different antenna orientations for the
GL2422MU-MT. Try to keep the antenna at least 6 inches away from the
wall or other objects.
If you are using 2.4GHz cordless phones, X-10 equipment or other home
security systems, ceiling fans, and lights, your wireless connection will
degrade dramatically or drop altogether. Try changing the Channel on
your Router, Access Point and Wireless adapter to a different Channel
to avoid interference.
Keep your product away (at least 3-6 feet) from electrical devices that
generate RF noise, like microwaves, Monitors, electric motors, etc.
The Encryption settings are: 64, 128 or 256-bit. Make sure that the encryption bit level is the same on the Router and the GL2422MU-MT.
Make sure that the SSID on the Router (if you have one in your network)
and the GL2422MU-MT are exactly the same. If they are not, wireless connection will not be established. The default SSID is default.
