11n protection mode has been enabled/disabled

Hello,


We are having big problems with users constantly loosing connection to the wireless network (MSM710 with six MSM410 APs) I activated debug logging on the AP:s and see the following messages repeated over and over...

21:12:40 debug kernel SG0032SW49 11n protection mode has been disabled
21:12:30 debug kernel SG0032SW49 11n protection mode has been enabled due to the presence legacy access points
21:12:15 debug kernel SG0032SW49 11n protection mode has been disabled
21:11:53 debug kernel SG0032SW49 11n protection mode has been enabled due to the presence legacy access points
21:11:52 debug kernel SG0032SW49 11n protection mode has been disabled

Some APs switch between enabled/disabled every 15 second without stopping. Is that normal behaviour or is it indicating a problem? I have only looked at the log while no user is connected so I don't know yet if it is the same when users are connected.

 

Thanks in advance
