I seem to get these messages from an 1130 LW, using a 4400 as the controller. Exactly every 20 minutes for the wholes days. Im around 10 meters away from the AP, and every now and then I get a low signal, then the wireless disconnects and reconnects.
AP 'comp-1130', interface '802.11b/g' on Controller '10.*.*.*'. Coverage threshold of 'unknown' violated. Total no of clients is 'unknown' and no of failed clients is 'unknown'.
The AP is between two other AP's. The other two have no problems. In the area, there are several 7920's and a couple other laptops that use the AP's continually.
