Basic Radio Settings

You can change the wireless network mode to suit the devices in your network,
specify the wireless channel and bandwidth for operation to resolve issues with
interference from other access points in the area, or enable the U-APSD and SSID
Isolation if needed.
Click Wireless -> Basic Settings.
The Basic Settings window opens.
Enter the following information:
• Wireless Radio: Click On to turn the wireless radio on and hence enable the
wireless network, or click Off to turn the wireless radio off. By default, the
security appliance turns on the wireless radio with predefined standard
settings.
• Wireless Network Mode: Choose the 802.11 modulation technique. The
ISA550W and ISA550W supports the following radio modes:
- 802.11b only: Choose this mode if all devices in the wireless network
use 802.11b. Only 802.11b clients can connect to the access point.
- 802.11g only: Choose this mode if all devices in the wireless network
use 802.11g. Only 802.11g clients can connect to the access point.
- 802.11b/g mixed: Choose this mode if some devices in the wireless
network use 802.11b and others use 802.11g. Both 802.11b and 802.11g
clients can connect to the access point.
- 802.11n only: Choose this mode if all devices in the wireless network
can support 802.11n. Only 802.11n clients operating in the 2.4 GHz
frequency can connect to the access point.
- 802.11g/n mixed: Choose this mode to allow 802.11g and 802.11n
clients operating in the 2.4 GHz frequency to connect to the access point.
- 802.11b/g/n mixed: Choose this mode to allow 802.11b, 802.11g, and
802.11n clients operating in the 2.4 GHz frequency to connect to the
access point.
• Wireless Channel: Choose a channel or choose Auto to let the system
determine the optical channel to use based on the environmental noise
levels for the available channels.
