Has someone seen this? Is this some weird software/hardware bug, or some scanner trying to get in? It is accompanies with few seconds drop on the link.

this is just a harmless log message. it says that someone was sending some data, but wasn’t even associated, so he was kicked and ignored.

This is a change from 2.8 behaviour, right? I’ve had a couple of users connect to us using Linksys Ethernet Bridges that appear to send using the MAC of the source computer, not the MAC of the radio card. Under 2.8 these show up as multiple entries in the wireless association table.

I assume in 2.9 these clients will have their traffic rejected?

This is with 2.8, and on a point-to-point link. No others are expected to connect and hide-ssid=yes, so this are not ranbom connects. Also, the messages occur in series, many at the sme time, with different MAC address!

Recently one of our links goes like this… The remote router have been crashed or locked up. After a hard restart everything goes to normal again
