No, the Centrino Advanced-N 6205 is not backward compatible with Intel AMT 4.0. The Intel ME needs to have the microcode for each supported wireless NIC in the firmware. The number of wireless NICs currently supported with each generation, Intel AMT 4.0, for example, is limited to what was available when the product generation was introduced. I don't know if this will change in the future, but for Intel AMT 4.0 you can't use the 6205 wireless NIC with Intel AMT 4.0.
Here are the approved wireless adapters:
- Intel® WiFi Link 1000
- Intel® WiFi Link 5100*
- Intel® WiFi Link 5300
- Intel® WiMax/WiFi Link 5150
- Intel® WiMax/WiFi Link 5350
*Includes Intel WiFi Link 5100 ABG for Centrino
