Troubleshooting the Client Adapter

This section provides troubleshooting tips should you encounter problems with your client adapter.

Problems Obtaining an IP Address

If your network is set up to use DHCP to acquire an IP address, the DHCP lease renewal may fail,
especially in suspend/resume situations. To force DHCP to try to reacquire an IP address, tap the Renew
button on the ACU Status screen, power your Windows CE device off and on, or eject and reinsert your
client adapter.

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 Windows CE device a few feet closer to an access point and try again.
Make sure the client adapter is securely inserted in your device's PC card slot.
Make sure that the access point is turned on and operating.
Ensure that all parameters are set properly for both the client adapter and the access point. These
include the SSID, WEP activation, EAP activation, infrastructure mode, etc.
If the client adapter still fails to establish contact, refer to the
section in the Preface for technical support information.
