Cisco Aironet 340, 350, and CB20A Wireless LAN Client Adapters Installation and Configuration Guide for Windows

OL-1394-07

Chapter 10 Troubleshooting

Troubleshooting the Client Adapter

Step 2

Click Start. The utility performs the following series of eight tests to check the operation of your client
adapter and to pinpoint specific problems if they exist:

1.

Checking driver installation

2.

Checking client adapter insertion

3.

Checking the client adapter’s radio (to see if it is turned on)

4.

Checking the client adapter’s association to an access point

5.

Checking authentication

6.

Checking the receive interrupt

7.

Checking network settings

8.

Checking the client adapter’s connection to the access point

The utility runs until it completes successfully or a problem is discovered. It then displays the results
(see

Figure 10-2

).
