- http://www.intel.com/support/wireless/wlan/sb/CS-024509.htm

### Recommended Power Configuration

A client disassociates upon moving from hibernation mode when the following conditions are met:

- A client is connected to an 802.1X profile.
- The Power Management setting in the Adapter Settings is configured to "Allow the device to bring the computer out of standby".
- In Windows, the system is configured to move automatically from standby to hibernation in the Power Option Properties.

The recommendation is to set the system hibernate power option to “Never” when the computer is on AC power.

### Known Issues

#### Operating in 802.11n Mode

Intel recommends using security with your WiFi network. The 802.11n specification indicates that a compliant adapter can achieve transfer rates greater than 54 Mbps on 802.11n connections only when using AES security or no security. You should only use no security when setting up or troubleshooting the network.

To enable AES for Personal Security, select WPA-Personal (AES-CCMP) or WPA2-Personal (AES-CCMP) in the Security Settings pulldown menu. To enable AES for Enterprise Security, select AES-CCMP in the Data Encryption pulldown menu.

#### Linksys* Access Point Association Timeout

After the association flow completes, the adapter stays awake (as in CAM mode) for 10 seconds, and then acts according to the PowerIndex (PI) regkey. PI should not be change during this period. The association timeout is 10 seconds. Using the Linksys access point, association occurs every 60 seconds, resulting in deauthentication and disconnection from the Linksys access point.

#### Intel My WiFi PAN Operation in the 5.2GHz Band

The Intel My WiFi PAN will operate over the 5.2 GHz band (802.11a) only when the adapter listed in Device Manager (Intel® My WiFi STA station for Windows Vista* or Intel® <adapter name> with PAN for Windows* 7) is connected to an access point that is operating over channel 36, 40, 44, or 48 (5.2 GHz).

#### Intel My WiFi PAN Device Reconnection After Profile Security Changes

In some instances a PDA may fail to immediately reconnect to the Intel My WiFi Technology network after the profile security is changed from one security setting to another.
