Wireless Configuration for ISA550W and ISA570W
Configuring the Radio Settings
Cisco ISA500 Series Integrated Security Appliance Administrator Guide 160
5
If you enable WMM, the wireless QoS settings control the downstream
traffic from the SSID to the client station and the upstream traffic from the
client station to the SSID. Fore more information about Wireless QoS, see
Configuring the Wireless QoS, page 150.
• Station Isolation: Check this box so that the wireless clients on the same
SSID will not be able to see eachother.
STEP 4 Click Save to apply your settings.
Advanced Radio Settings
Use the Advanced Settings page to specify the advanced radio settings, such as
Guard Interval, CTS Protection Mode, and so forth.
STEP 1 Click Wireless -> Advanced Settings.
The Wireless Advanced Settings window opens.
STEP 2 Enter the following information:
• Guard Interval: Choose either Long (800 ns) or Short (400 ns) that the
security appliance will retry a frame transmission that fails.
NOTE The short frame is only available when the specified wireless network
mode includes 802.11n.
• CTS Protection Mode: CTS (Clear-To-Send) Protection Mode function
boosts the ability of the access point to catch all Wireless-G transmissions
but will severely decrease performance.
- Click AUTO if you want to perform a CTS handshake before transmitting
a packet. This mode can minimize collisions among hidden stations.
- Click Disabled if you want to permanently disable this feature.
• Power Output: You can adjust the output power of the access point to get
the appropriate coverage for your wireless network. Choose the level you
need for your environment. If you are not sure of which setting to select, then
keep the default setting, 100%.
