- 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".

### 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.

#### Share My Internet Behavior After Reinstalling Intel® My WiFi Technology

If the user has enabled Internet Connection Sharing (via the Windows 7 Network Connections), and then uninstalls and reinstalls Intel® My WiFi Technology, then Share My Internet will no longer function. To avoid this condition, first disable Internet Connection Sharing (if enabled) before uninstalling or reinstalling Intel® My WiFi Technology. To correct this condition after the fact, perform these steps:

1. Open the Control Panel. Select Network and Internet > Network Connections.
2. Select the network adapter used for internet sharing.
3. Right-click, open Properties, and select the Sharing tab.
4. Disable Allow other network users to connect through this computer’s Internet connection.
5. Now open the Intel® My WiFi Technology utility and click Share My Internet.

#### 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® <adapter name> with PAN) 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.

Intel® My WiFi Technology failed to enable due to unsupported channel

The following message may display:

Intel® My WiFi Technology failed to enable because the wireless adapter is connected to the access point using an unsupported channel.

If the wireless adapter is connected to the access point using a channel that is not supported by Intel® My WiFi Technology, then the application will not operate. To correct this, it is recommended that you determine the channel supported for your country and change the channel at the access point to match.
