Event Log Wrong!

[#1]

I have my printer wirelessly connected to my Tg582 and all works beautifully including airprint.  However the event log shows a message every 10 minutes 'wireless device can't get authorised' for the printer.  Anyone know why?

Is the message LOGIN wireless station [xx:xx:xx:xx:xx:xx] can't get authorized?

Yes, that's it.
