• universal client; association to an access point running in guest mode is not supported. The universal client can associate to Cisco access points, third party access points, and repeaters. It • cannot associate to Cisco root bridges or Cisco workgroup bridges. -
Page 4: Configuring Universal Client Mode
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. -

Page 10: Configuring Dynamic Frequency Selection On An Access Point
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.

Enabling and Disabling World Mode on an Access Point Perform this task to configure the AP to support 802.11d world mode or Cisco legacy world mode. When you enable world mode, the AP adds channel carrier set information to its beacon. Client devices with world mode enabled receive the carrier set information and adjust their settings automatically. - Page 14 Configuring Radio Settings on an Access Point How to Configure Radio Settings on an Access Point Command or Action Purpose Step 5 Returns to privileged EXEC mode.

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. -

Aironet extensions are enabled by default. Benefits of Enabling Aironet Extensions By default, the AP uses Cisco Aironet 802.11 extensions to detect the capabilities of Cisco Aironet client devices and to support features that require specific interaction between the AP and associated client devices. - Page 18 AP sends the maximum allowed power level setting to the client. Disabling Aironet extensions disables the features listed above, but it sometimes improves the ability of non-Cisco client devices to associate to the access point. SUMMARY STEPS enable...
