Hello averyone,
I manage a network consisting of a Vigor 2925, 3x VigorAP 910C and a few various switches (HP, Netgear, Cisco,...).
Due to some strange occasional wifi disconnecting reported to me, I've turned on syslog monitoring on AP's.
One of the AP's is reporting a lot of errors, but I don't know what they mean.

error no.1 (a LOT of it):

Can anyone explain what they mean?
