My wireless WLAN AP is randomly dropping clients, or so I believe. Every 2 or 3 days a client is still connected to the network but unable to communicate with any other devices. A simple connection repair fixes the problem. The clients are using Cisco Aironet cards, AIR-CB21AG-A-K9. Attached are 2 screenshots:
1. A screenshot of Networkstumbler, you can see that alot of devices are running on channel 11. The AP in question has MAC 001874F826C1
2. A screenshot of a client that just "dropped" off the network, before repairing the wireless connection.
