The Wireless Tab - Wireless MAC Filter

Wireless access can be filtered by using the MAC addresses of the wireless devices transmitting within your network's radius.
Wireless MAC Filter. To filter wireless users by MAC Address, either permitting or blocking access, click Enable. If you do not
wish to filter users by MAC Address, select Disable.
Prevent. Clicking this button will block wireless access by MAC Address.
Permit Only. Clicking this button will allow wireless access by MAC Address.
Edit MAC Address Filter List. Clicking this button will open the MAC Address Filter List. On this screen, you can list users, by
MAC Address, to whom you wish to provide or block access. For easy reference, click the Wireless Client MAC List button to
display a list of network users by MAC Address.
Change these settings as described here and click the Save Settings button to apply your changes or Cancel Changes to
cancel your changes.

The Wireless Tab - Advanced Wireless Settings

This tab is used to set up the Router's advanced wireless functions. These settings should only be adjusted by an expert
administrator as incorrect settings can reduce wireless performance.
Authentication Type. The default is set to Auto, which allows either Open System or Shared Key authentication to be used.
With Open System authentication, the sender and the recipient do NOT use a WEP key for authentication. With Shared Key
authentication, the sender and recipient use a WEP key for authentication.
Basic Rate. The Basic Rate setting is not actually one rate of transmission but a series of rates at which the Router can
transmit. The Router will advertise its Basic Rate to the other wireless devices in your network, so they know which rates will
be used. The Router will also advertise that it will automatically select the best rate for transmission. The default setting is
Default, when the Router can transmit at all standard wireless rates
(1-2Mbps, 5.5Mbps, 11Mbps, 18Mbps, and 24Mbps). Other options are 1-2Mbps, for use with older wireless technology, and
All, when the Router can transmit at all wireless rates. The Basic Rate is not the actual rate of data transmission. If you want
to specify the Router's rate of data transmission, configure the Transmission Rate setting.
Transmission Rate. The rate of data transmission should be set depending on the speed of your wireless network. You can
select from a range of transmission speeds, or you can select Auto to have the Router automatically use the fastest possible
data rate and enable the Auto-Fallback feature. Auto-Fallback will negotiate the best possible connection speed between the
Router and a wireless client. The default value is Auto.
CTS Protection Mode. CTS (Clear-To-Send) Protection Mode should remain disabled unless you are having severe problems
with your Wireless-G products not being able to transmit to the Router in an environment with heavy 802.11b traffic. This
function boosts the Router's ability to catch all Wireless-G transmissions but will severely decrease performance.
Frame Burst. Enabling this option should provide your network with greater performance, depending on the manufacturer of
your wireless products. If you are not sure how to use this option, keep the default, Disable.
