Known Issues and Limitations

Operating in 802.11n Mode

Intel recommends using security with your wireless network. Note that 802.11n mode is limited to WPA2 - AES security methods. You should only use no security when setting up or troubleshooting the network.

AES Security

To enable AES for Personal Security, select WPA-Personal (AES-CCMP) or WPA2-Personal (AES-CCMP) in the Security Settings pull down menu. To enable AES for Enterprise Security, select AES-CCMP in the Data Encryption pull down 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 Intel My WiFi STA station 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 MyWiFi Technology network after the profile security is changed from one security setting to another.
