Radio Interface

The IEEE 802.11a and 802.11g interfaces include configuration options for radio signal characteristics and wireless security features. The configuration options are nearly identical, and are therefore both covered in this section of the manual.

The access point can operate in several different radio modes, IEEE 802.11a only, 802.11b only, 802.11g only, 802.11b/g only, or a mixed 802.11a/b/g mode. Also note that 802.11g is backward compatible with 802.11b. These interfaces are configured independently under the following web pages:

•Radio Interface 1: 802.11a

•Radio Interface 2: 802.11b/g

Note: The radio channel settings for the SMC2555W-AG are limited by local regulations, which determine the number of channels that are available.
