Follow the instructions below if your client adapter fails to associate to the Access
Point.
• If possible, move your workstation a few feet closer to the Access Point and
try again.
• Make sure the client adapter is securely inserted in your computer's PC card
slot or PCI expansion 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, LEAP or EAP activation, WEP
activation, network type, and channel.
If the client adapter still fails to establish contact, refer to the "Obtaining
•
Technical Assistance" section on page xvii for technical support information.
If your client adapter is a 40-bit card and LEAP is enabled, the adapter can
associate to but not authenticate to Access Points using 128-bit encryption. To
authenticate to an Access Point using 128-bit encryption, you have two options:
Purchase a 128-bit client adapter. This is the most secure option.
•
Disable WEP for the client adapter and configure the adapter and the Access
•
Point to associate to mixed cells. This option presents a security risk because
your data is not encrypted as it is sent over the RF network.
After you have installed the appropriate driver and client utilities, contact your IS
department if you have a problem connecting to the network. Proxy server,
network protocols, and further authentication information might be needed to
connect to the network.
