Configuring Radio Settings on an Access Point
This module describes how to configure radio settings on a Cisco 800, 1800, 2800, or 3800 series
integrated services router, hereafter referred to as an access point (AP).

    Perform this task to configure universal client mode. You can configure universal client mode on a Cisco ISR series router by setting the radio interface station role to nonroot. This is different from configuring the dot11radio interface to operate in non-root bridge mode, which requires specifying the word bridge at the end of the command, for example, station-role non-root bridge.

    This section applies only to wireless access points shipped to Europe and Japan with 5-GHz radios running Cisco IOS version 12.4(6)T. Access points shipped to Europe and Japan with 5-GHz radios are required to use DFS to detect and avoid interfering with radar signals to comply with that regulatory domain.
  • Page 11 5-GHz channel on which power is restricted, the access point automatically reduces transmit power to comply with power limits for that channel. Cisco recommends using the world-mode dot11d country-code interface configuration command to Note configure a country code on DFS-enabled radios. The IEEE 802.11h protocol requires access points to include the country information element (IE) in beacons and probe responses.

    Adapters support short preambles. Early models of Cisco Aironet's Wireless LAN Adapter (PC4800 and PC4800A) require long preambles. Long—A long preamble ensures compatibility between the AP and all early models of Cisco • Aironet Wireless LAN Adapters (PC4800 and PC4800A). If these client devices do not associate to your access points, you should use short preambles.
