Problems Associating to an Access Point
Follow the instructions below if your client adapter fails to associate to an access point.
• If possible, move your workstation a few feet closer to an access point and try again.
• Make sure the client adapter is securely inserted in your computer’s client adapter slot.
• If you are using a PCI client adapter, make sure the antenna is securely attached.
• Make sure the access point is turned on and operating.
• Check that all parameters are set properly for both the client adapter and the access point. These
include the SSID, EAP authentication, WEP activation, network type, channel, etc.
