Locally Administered MAC Address

Locally Administered MAC Address is used to override the MAC address of the Wireless
MAXg USB Adapter. The Locally Administered MAC Address is a user-defined MAC address
that is used in place of the MAC address originally assigned to the network adapter. Every
adapter in the network must have its own unique MAC address. This locally administered
address consists of a 12-digit hexadecimal number.

Value Assigns a unique node address for the adapter.

Not Present (Default). Uses the factory-assigned node address on the adapter.

The appropriate assigned ranges and exceptions for the locally administered address
include the following:

● The range is 00:00:00:00:00:01 to FF:FF:FF:FF:FF:FD.

● Do not use a multicast address (least significant bit of the high byte = 1).

● Do not use all 0s or all F's.

Mixed Cell Support

Mixed Cell Mode is a wireless network environment in which the use of WEP encryption is
optional. If "optional encryption" is enabled on the access point, wireless clients that are
using WEP encryption send all messages encrypted. At the same time, wireless clients
that are not using WEP encryption send all messages unencrypted. Access points, that
support mixed cell mode, broadcast that the network is not using encryption, but allow
clients to use WEP encryption. When Mixed Cell Support is enabled, the wireless adapter
can connect to access points that have “optional encryption” enabled.

Disabled (Default)

Enabled

Power Output

The power output property allows users to reduce the power output of the radio and
therefore, the noise level, if excessive noise is a problem.

Priority & VLAN

The Priority & VLAN property controls IEEE 802.1p packet priority and the VLAN identifier
(ID). When the property is set to Priority Enabled or Priority & VLAN Enabled, the driver
supports “User Priority” values that correspond to the following access classes:
background (BG), best-effort (BE), video (VI), and voice (VO). When the property is set
to Priority & VLAN Enabled or VLAN Enabled, the driver removes VLAN ID marking in the
MAC headers of packets. When the property is set to Priority &VLAN Disabled, the
packets in the queue are transmitted on a first-come, first-served basis, regardless of
any priority information within the packet.

Priority & VLAN Disabled (default)

RTS Threshold

RTS Threshold sets the maximum number of frames allowed in a data packet before the
Request To Send/Clear To Send Handshake is used. When the RTS Threshold is
exceeded, the adapter sends a Request To Send message to the access point prior to
sending data. When the access point receives the the Request To Send message, it

file:///G|/CSO/T-Writer%20Repository/Networking/5425...Refresh%20USB/User%20Guide/English/config_vista.html (19 of 20)6/26/2007 9:29:33 AM

Wireless MAXg USB Adapter: User Guide

broadcasts a Clear To Send message. This message tells the requesting adapter to send
its message while telling other adapters to refrain from sending data while the requesting
adapter sends its message. In environments where there are frequent data collisions
between wireless adapters, decreasing the RTS threshold can decrease collisions and
improve network performance. However, each RTS/CTS handshake adds communication
overhead that can decrease network performance.

The default value is 2347. The range is 0 to 2347.

WMM

Wi-Fi Multimedia (WMM™). The WMM property enables quality of service for audio, video,
and voice applications over a wireless network by prioritizing streams of content and

optimizing the way the network allocates bandwidth among competing applications.

point, and the access point has Unscheduled Automatic Power Save Delivery (UAPSD)
enabled, the wireless client is allowed to enter Power Save mode.

Enabled The wireless client enters Power Save mode for WMM associations independent
of whether the access point has UAPSD enabled or disabled.

Disabled The wireless client does not have WMM association.

WZC IBSS Channel Number

The WZC IBSS Channel Number property selects the independent basic service set
(IBSS) channel number on which to operate when WZC is managing your wireless
networks. The default setting is 11.

I cannot achieve MAXg (125 Mbps) connections to a Wireless MAXg Router.

Possible Solution:

Make sure you have MAXg enabled for the Acceleration option in the Wireless section of
the Wireless MAXg Router's Web User Interface. This can be found in the Transmission
area in the Wireless section. Launch the Web User Interface, click the Wireless tab, and
manually set the Acceleration to MAXg within the Transmission area.

Possible Solution:

Low link quality or range can be caused by environmental interference, such as lead-based
paint and concrete walls. Try to move the antenna of the Wireless MAXg Router or to
reposition the wireless clients to improve the link quality.

Possible Solution:

Some electronic devices, such as 2.4Ghz phones and microwave ovens, may interfere with
the wireless signal and affect your wireless range and link quality. Try creating a wireless
connection on a different channel.

Possible Solution:

If there is any wireless client that does not support the MAXg feature connected to the
Wireless MAXg Router, the Wireless MAXg Router will switch to normal 54g mode and will
not use MAXg acceleration.

Frequently Asked Questions

What is 802.11 wireless networking?

802.11 (sometimes called "Wi-Fi") is a set of protocols that are widely used
for small Local Area Networks. Another protocol called Bluetooth allows
devices to communicate wirelessly, but it is only useful for very short
ranges, and generally not used for home networking. Bluetooth can be
useful for networking personal devices in a small area, often called a
Personal Area Network (PAN).

802.11 actually encompasses several different protocols. The trailing letters
(i.e. the g in 802.11g) indicate different speeds and frequency bands used.

What kind of wireless antenna range performance issues might affect my
wireless connection?

Radio waves don't really travel the same distance in all directions. Walls,
doors, elevator shafts, people, and other obstacles offer varying degrees of
attenuation, which cause the Radio Frequency (RF) radiation pattern to be
irregular and unpredictable. Attenuation is simply a reduction of signal
strength during transmission. Attenuation is registered in decibels (dB),
which is ten times the logarithm of the signal power at a particular input
divided by the signal power at an output of a specified medium. For
example, an office wall (i.e., medium) that changes the propagation of an
RF signal from a power level of 200 milliwatts (the input) to 100 milliwatts
(the output) represents 3 dB of attenuation. The following provides some

Wireless MAXg USB Adapter: User Guide

examples of the attenuation values of common office construction:

Plasterboard wall: 3dB
Glass wall with metal frame: 6dB
Cinder block wall: 4dB
Office window: 3dB
Metal door: 6dB
Metal door in brick wall: 12.4dB
Other factors that will reduce range and affect coverage area include
concrete fiberboard walls, aluminum siding, pipes and electrical wiring,
microwave ovens, and cordless phones.

What should I do if I am unable to access my e-mail or the Web page of my ISP?

You should contact your ISP to get the full URL and then perform the
following steps:

Note: Linux users can perform steps 3 and 4 after opening a

terminal.

1. Connect your broadband modem directly to one of your computers.

2. Open a command prompt as follows:

❍ Windows Vista:

A. Click Windows Start.

B. In the Search box, type Command Prompt and press

ENTER.

C. In the result list, double-click Command Prompt.

❍ All other Windows operating systems:

A. Click Windows Start > Run.

B. In the Run dialog box:

Windows XP, 2000, and NT: Type cmd and click OK.
Windows Me, 98, and 95: Type command and click

3. All users should then enter the following command: ping xxx, where

xxx is the complete URL for your ISP.

4. After you get the IP address, enter the IP address in the mail server
option or in the address line of your Web browser.

Can the wireless router I am wirelessly networked with be used in place of a
modem?

No, a broadband modem must still be used to have Internet access over the
wireless network.
