Field Notice: Cisco Aironet AP1200 Series: Resetting to Factory Defaults Modifies the Country Setting to North America

August 5, 2002

Products Affected

  • AIR-AP1220B-J-K9

  • AIR-MP20B-J-K9

  • AIR-MP20B-J-K9=

  • AIR-AP1220B-E-K9

  • AIR-MP20B-E-K9

  • AIR-MP20B-E-K9=

Problem Description

Following a reset to factory defaults, the AP1200 will be set to the US/FCC regulatory setting. The country mode cannot be changed back to ETSI or Japan settings.


The regulatory setting (US, ETSI, or Japan) determines the legally allowed channel settings for a particular country or region. If a unit originally set for Japan or Europe changes to settings approved only for North America, some channels may no longer be available.

Problem Symptoms

The unit will not function as designed. Some channels may be dropped, which will affect site surveys and coverage as well as country regulations. The power level will not be affected.


At this time there is no workaround. Contact the Cisco Technical Assistance Center to submit a return materials authorization (RMA), coded ARFN (Administrative Request - Field Notice) if this issue has occurred. This issue is seen with firmware version 11.42T or lower. Once this issue occurs, it cannot be resolved with newer firmware. The next firmware release (11.50) will, however, prevent that situation from happening, and will be on by the end of August, 2002.
