	Symptom	Solution(s)

16 devices have been connected to the Ethernet Adapter, either simultaneously or sequentially. After connecting another device, the new device cannot associate with the network.

The Ethernet Adapter supports up to 16 specific clients (for example, computers and printers) and keeps track of them using a client list of MAC addresses. After the client limit is reached, you must clear the client list to allow a new client to associate. For example, in a hub configuration with 16 clients connected, if you disconnect a desktop computer and connect a laptop in its place, you must clear the client list to establish network association.

1Disconnect a client by unplugging its Ethernet cable from the hub.

2Use the Enterasys Networks Wireless Infrastructure Device Manager to select the Ethernet Adapter and launch its Configuration Management System.

3Under System Configuration, click Ethernet Client List. The Ethernet Client List page appears. Click Clear Client List.

4Connect the new client by plugging its Ethernet cable into the hub.
