[ipw2200] wireless connection gets constantly disconnected

[johny]

My wireless connection gets constantly disconnected. Even when it will connect successfully, the signal will get down all of sudden an then it will disconnect again and again. Sometimes unloading and loading again the ipw2200 drivers helps, but rather casually. I'm attaching some logs from deamon.log.

Thanks in advance
