The Association Timeout (seconds) is 300 seconds by default, and the allowed range is from 
60 to 36000 seconds. If your network is very busy, you can increase the timeout by increasing 
the number of seconds in the Association Timeout (seconds) field. 

Set the Maximum Client Associations to limit the number of stations that can connect 
wirelessly at one time. The default is 128.

Data Rate: Select the speed at which the data is transmitted and received. Best automatically 
selects the best rate available in your area given interference and other factors. Or you can 
manually select a data rate.

Protection Mode: Protection can decrease collisions, particularly where you have two 
overlapping SonicPoints. However, it can slow down performance. Auto is probably the best 
setting, as it will engage only in the case of overlapping SonicPoints.

Protection Rate: The protection rate determines the data rate when protection is on. The 
slowest rate offers the greatest degree of protection but the slowest data transmission rate. 
Choose 1 Mbps, 2 Mbps, 5 Mbps, or 11 Mbps.

Protection Type: Select the type of handshake used to establish a wireless connection: CTS-
only or RTS-CTS. 802.11b traffic is only compatible with CTS.

Click Apply in the top right corner of the page to apply your changes to the security appliance. 

Click Restore Default to return the radio settings to the default settings.

The dual antenna wireless SonicWALL security appliances employ two 5 dBi antennas running 
in diversity mode. The default implementation of diversity mode means that one antenna acts 
as a transmitting, and both antennas act as potential receiving antenna. As radio signals arrive 
at both antennas on the secure wireless appliance, the strength and integrity of the signals are 
evaluated, and the best received signal is used. The selection process between the two 
antennas is constant during operation to always provide the best possible signal. To allow for 
external (higher gain uni-directional) antennas to be used, antenna diversity can be disabled.

The SonicWALL NSA 220 and 250M wireless security appliances employ three antennas. The 
Antenna Diversity is set to Best by default, this is the only setting available for these 
appliances.

The Antenna Diversity setting determines which antenna the wireless security appliance uses 
to send and receive data. You can select:

Best: This is the default setting. When Best is selected, the wireless security appliance 
automatically selects the antenna with the strongest, clearest signal. In most cases, Best 
is the optimal setting. 

1: Select 1 to restrict the wireless security appliance to use antenna 1 only. Facing the rear 
of the appliance, antenna 1 is on the left, closest to the console port. You can disconnect 
antenna 2 when using only antenna 1. 

2: Select 2 to restrict the wireless security appliance to use antenna 2 only. Facing the rear 
of the appliance, antenna 2 is on the right, closest to the power supply. You can disconnect 
antenna 1 when using only antenna 2.
