3. Wireless LAN Basics
Wireless LAN (Local Area Networks) systems offer a great number of advantages over a traditional,
wired system. Wireless LANs (WLANs) are more flexible, easier to setup and manage and often more
cost effective than their wired equivalence.
Using radio frequency (RF) technology, WLANs transmit and receive data over the air, minimizing the
need for wired connections. Thus, WLANs combine data connectivity with user mobility, and, through
simplified configuration, enable movable LANs.
With wireless LANs, users can access shared information without looking for a place to plug in and
network managers can set up or augment networks without installing or moving wires. Wireless LANs
offer the following productivity, convenience and cost advantages over traditional wired networks:
• Mobility - Wireless LAN systems can provide LAN users with access to real-time information
anywhere in their organization. This mobility supports productivity and service opportunities not
possible with wired networks.
• Installation Speed and Simplicity - Installing a wireless LAN system can be fast and easy and can
eliminate the need to pull cable through walls and ceilings.
• Installation Flexibility - Wireless technology allows the network to go where wires cannot go.
• Reduced Cost-of-Ownership - While the initial investment required for wireless LAN hardware
might be higher than the cost of wired LAN hardware, overall installation expenses and life-cycle
costs will be significantly lower. Long-term cost benefits are greatest in dynamic environments
requiring frequent moves, adds, and changes.
• Scalability - Wireless LAN systems 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 full infrastructure networks of thousands
of users that allows roaming over a broad area.

5. Configuration Utility
GemTek Inc USB Card Wireless LAN adapter (GemTek NIC) uses his own management software. All
functions controlled by user are provided by this application. Usually this application starts
automatically, Use Start, Programs, GemTek Wireless LAN to start the Manager application.
A new icon - should appear in your Icon tray. If the icon is marked with a red “X”, it means that
GemTek NIC configuration is invalid or incomplete. Sometimes icon can be colored in red. This can
happen when driver is in Pseudo BSS mode, and the radio channel, which is used for communication
is defined incorrectly.
Figure 1 Icon tray with a new icon
Figure 2: Error Icon
Double clicking on that icon will show you the screen as shown below.
Figure 3 Management window with “Status” tab open
User can navigate through “sheets”, by clicking or tapping them with a stylus. “OK” button will minimize
window, and “Exit” (or X button) will close application. Here we explain the use and meanings of the
various screen messages.
The first three fields show your wireless network card state.
Link status – indicates link accessibility. There are several values, that can be shown in this part of
the window:
Connected - BSSID=… – normal flow of operation in Infrastructure mode. The PC is connected to
access point. BSSID is shown in the form of hex digits. Networking is available.
No status… - the manager is retrieving information from the driver. If this text box value stays more
than several seconds, it means that there are no access points or other workstations (if
communicating in AdHoc mode), or that the GemTek NIC card is plugged out of PC.
Scanning for access point – driver scans wireless network searching for available access point
in Infrastructure mode.
Disabled or disconnected - . If this text box value stays more than several seconds, it means that
there are no access points or other workstations (if communicating in Pseudo BSS mode), or
that the GemTek NIC card is plugged out of PC.
Undefined– means critical driver error. This error is usually caused by hardware misconfiguration
(for example the card with similar chipset inserted in USB Card bay, but not fully compatible with
GemTek NIC).
Input bytes/sec – shows the incoming (received) data speed, the progress bar below, means receiver
load.
Output bytes/sec – shows the outgoing (sent) data speed, the progress bar below, shows transmitter
load.
Signal strength : bar shows signal strength level. The higher blue bar is, the more powerful is radio
signal received by Gemtek USB Card. This indicator helps to find the most comfortable
antenna/workstation position for quality network operation.
Link quality: The measured signal level gives the overall Link Quality and Connection Status.
“CONFIGURATION” tab
You can change the configuration by clicking on the Change Configuration. When you click on the
Change Configuration, you see the screen given below.
Figure 4 Management window with "CONFIGURATION" tab open
Five changeable fields in this field show desired GemTek NIC configuration.
The fields are following:
Station ESS ID Extended Service Set Identifier (Wireless Network Identifier) is the group name that
will be shared by every member of your wireless network. You will only be able to connect with an
Access Point, which has the same ESS ID.
Network mode shows one of these network modes:
• Pseudo BSS -this is the 802.11 peer-to-peer mode of operation. In Ad Hoc only one wireless
"cell" is supported for each different ESS ID. All communication is done from Client to Client
without the use of an Access Point.
• Infrastructure This mode of operation requires the presence of an 802.11 Access Point. All
communication is done via the Access Point, which relays packets to other wireless Clients in
the BSS (Basic Service Set) as well as to nodes on a wired network such as Ethernet.
Encapsulation shows one of two different network packet forming modes
• None or Encapsulated This setting takes the entire Ethernet frame, including the Ethernet
Header, and puts it into an 802.11 frame. This setting is here for compatibility with some older
802.11 implementations and should not normally be used.
• RFC1042 where the DIX Ethernet frames are converted using SNAP header based on
RFC1042. This mode will also convert any RFC1042 SNAP header frames to DIX Ethernet
frames before transmission to the Ethernet interface.
• 802.1h where the DIX Ethernet frames are tunneled using a full selective translation table. This
mode does not convert RFC1042 SNAP header frames to DIX Ethernet before transmission to
the Ethernet interface
It is required to select encapsulation mode corresponding to the one your access point or other
workstations use. If the encapsulation mode is incorrect, the PC will join to access point or will
be seen by other workstations, but network operation will not work.
Channel – shows radio channel number used for networking. Only Access Points and Ad Hoc nodes
can create a BSS therefore this parameters is not active if Mode is Infrastructure. Infrastructure Client
nodes will always go the same channel as their AP. Please see the table for the requirements of
different countries and the channel frequency.
TX Rate: The transmission rate at which the data packets are transmitted by the client or AP. You can
set this to Auto select I or 2Mbps, Fixed 1 Mbps, Fixed 2 Mbps, Fixed 5.5 Mbps, Fixed 11 or Full Auto
(I to 11 Mbps).
Important: You must know the TX Rate that your AP can support. Failure to which may
cause the undesired results.
“ENCRYPTION” tab
Figure 5 Management window with “Encryption” tab open
You may desire an additional measure of security on your wireless network, which can be
achieved by using WEP (Wired Equivalent Privacy) encryption. WEP encrypts each frame
transmitted from the radio using one of the Keys entered from this panel.
When an encrypted frame is received it will only be accepted if it decrypts correctly. This will only
happen if the receiver has the WEP Key used by the transmitter.
This panel allows the entry of four keys, which can then be written to the driver and registry. Each
key must consist of hex digits, it means that only digit 0-9 and letters A-F are valid entries. If
entered incorrectly program will not write keys to a driver.
Key 1 – Key 4: These four fields must be used to enter the keys.
Write : This button updates the driver with the four keys displayed in Key1 through Key4. The keys
are also written to the registry for permanent storage.
Clear : This button clears all the bytes in the four keys, useful when entering and you wish to start
over.
Default Key : This pop-up field defines one of the four keys which will be used by the driver to
encrypt frames it will be transmitting. This field does not affect decryption, as the driver can
decrypt any frame that it receives which was encrypted with one of the four keys.
Enable : This checkbox enables or disables encryption operation. When it is checked, encryption
is enabled, and when unchecked – encryption is disabled. The corresponding action is written to a
driver immediately.
“ABOUT” tab
Figure 6 Management window with "ABOUT" tab open
About tab shows a software version. Users must use this version number when reporting their
problems to tech support.
