AP 3610 logs

[Aaron Russell]

Hello everyone,
I was hoping someone could give me a quick insight on these specific
messages i see inside /tmp/ap.log on my wireless APS. I can open a support
case but didnt want to bother unless there is something wrong.
It would seem this is a client issue but I wanted to make sure.

I had a user get disconnected from the wifi and could get back on for about
a minute. Here are the only logs I see relevant to the disconnect.

Hi Aaron,
Those messages look ok, just standard deassosiations.
Do you have any particular issues with client(s)?

So only this one person so far. No one else has reported it. It seems to
happen to him once a week but I can never replicate it.

If those looks normal I think its a local client issue on his Mac air.

I see similar entries in my logs. I do not know what they mean other than the user is being deauthenticated possibly because it has hit some timeout.

802.1x or WPA auth? There are a lot of different options in play depending on the security. What is your 802.1x reauth set at? What is your re-key interval?

Did the client fall asleep or did some other energy saving mechanism kick in between 17:01:02 and 17:04:51?

What model of MBA? What OS? Patched? There are many known issues with various versions of Mac OS.
