Aironet 1400 Interference?

[cameron.stephens]

I have an Aironet 1410 which has been online for the past 3-4 months with no problems at all. The other day we noticed these messages coming through (I have removed mac addresses and host names).

This message then keeps repeating, and the link is almost unusable with regular timeouts to users and access to the remote 1410's web interface. Yesterday the messages stopped and the link is now as stable as it was before. Is this is an interference problem and is there anything I can do about it? I tried rebooting both devices and they switched to a different frequency (they are set to Least Congested Frequency) but this made no difference.

The message indicates that AP has failed to reach associated workstation over radio and therefore it (AP) deassociates workstation. The reason for this, apparenly, is reachability of workstation over Radio. Can you make sure that your workstation is in the good area of signal strength and quality? Also make sure that there's no nearby AP which has overlaping adjacent channels with the AP in the questions.

if possible try use airmagnet spectrum analyzer .... same scenario and with this utility I could be able to register and measure the amount of interference I had within my facilities; even though I had good signal strength I couldn't grant acces to my applications; as soon as we identified interference source (spectrum analyzer provides lets you track it) problem was solve
