Troubleshooting with Cisco Aironet Client Diagnostics

Cisco Aironet Client Diagnostics is a mode that identifies communication problems between the client adapter and a wireless LAN infrastructure device. When in this mode, the client adapter and the infrastructure device proceed through a defined set of tests. The results of these tests can assist in isolating conditions that require troubleshooting.

Cisco Aironet Client Diagnostics can only be started manually. To start this mode, follow these steps:

Step 1 Verify that the client adapter radio is enabled. If the radio is not enabled, enable it.

Step 2 Choose Start > Control Panel > Network and Sharing Center. The Network and Sharing Center window opens (see Figure 6-1).

Figure 6-1 Network and Sharing Center Window

Step 3 Click Cisco Aironet Client Diagnostics. The Cisco Aironet Client Diagnostics dialog box appears (see Figure 6-2).
