I have enabled the the in-service scan on one AP3825i access point to
test the Radar feature. Since I've enabled it at the morning the Radar reports "WEP or WPA-PSK active encryption attack" in the log.
Based on my knowledge this could be caused by excessive FCS errors and other reasons. I discovered the same behavior during severals other tests at different locations. For me it looks like a false positive. The Wireless Statistic Report of the access point shows a large FCS Error Count on Radio 1 (5 GHz):

Anyone else has the same alarms?
