8-2 Advanced Network Configurations
To set the advanced parameters, simply follow the instructions as described in
the previous section, “Configuring Infrastructure Networks” on page 4-2, to
connect to the Access Point that you wish to configure.
Advanced Parameters
If you created a basic Access Point configuration, as described in the previous
section, you may have already noticed the additional buttons in the setup
window, as pictured in Figure 4-4 on page 4-5.
Frequency
The Frequency setup menu gives you the ability to select an operating frequency
from a range of sub-channels within the 2.4 GHz frequency band.
The number of selectable channels is determined by the radio regulations that
apply in your country.
Click the
Advanced
button on the
Wireless Interfaces
tab of the edit mode to change
the frequency parameters.
To optimize network traffic, we recommend that you assign different operating
frequencies to Access Points that service neighboring wireless cells. Doing so,
stations in each of the cells will be able to use the maximum bandwidth available
to their cell.
Wireless stations equipped with Wireless Client Adapters can dynamically
change the operating channel when roaming between Access Points that operate
at different sub-channels.
RTS/CTS Medium Reservation
RTS/CTS medium reservation may provide a solution for networks where:
■
Density of stations and Access Points is very low.
■
You witness poor network performance due to excessive frame collisions at
the Access Points.
However in most networking environments it is very unlikely that you will need
to enable RTS/CTS medium reservation on the Access Point to prevent
collisions. You are advised to read the information about “Optimizing Wired
Connections” on page 6-4 prior to changing this setting for the Access Point.
To enable RTS/CTS medium reservation click the
Advanced
button on the
Wireless Interfaces
tab.
Interference Robustness
The Interference Robustness can be activated in exceptional cases when
troubleshooting slow performance of your network that could be related to in-
band interference from e.g. microwave ovens. Interference will usually show a
poor Signal to Noise Ratio (SNR) that is based upon a good signal level and a
high noise level. This behavior is often perceived when:
— the “trouble” station or Access Point is close to a interference source, or
