We recently moved to a more secure WLAN using WPA encryption. Now at various times throughout the day all the clients connected to the AP are disconnected. The errors in the event log of the AP are, "Received TKIP Michael MIC failure report from the station <####.####.####> on the packet (TSC=0x0) encrypted and protected by group key" This same error exists in the event log for all the clients MAC addresses. The clients will reconnect automatically after 60 seconds. Any thoughts on what may be causing this?

We were using WEP security prior to this, with no problems.
