I have a 5 WNAP320's in a few buildings.
They disconnect clients throughout the day a few times. This happens at any time and doesn't matter if the user is in the middle of an email, on the web, or if the device is not in active use. To resolve this users either:
a. reboot computer
b. reboot A.P.
c. turn wireless reception off and on (on computer)

I can see the "full bars" when I am disconnected. When I connect to the log this is what I see (below). My device is e4:ce:8f:78:25:5e. For example, I experienced the symptoms above at 10:19am

Thanks for your help in diagnosing and hopefully resolving this.

Here is the log for a few hours:
