I'm having a strange problem.
Every few days my Pi looses the connection to my Wi-Fi and only after I disconnect and connect the Pi to the power supply does the connection come back.
I saw in the /var/log/messages the lines:

Does anyone has an idea why this is happening?
(I do not think it's a power supply problem).
