I'm not sure whether it's a problem but it is occuring very very frequently and this may be interfering with station operation. >How-To-Repeat: * enable 11n * throw the AP into a busy 2.4ghz environment with non-11n stuff around you * wlandebug +11n >Fix: Not known. >Release-Note: >Audit-Trail: >Unformatted:
