Wi-Fi* Connections

The wireless feature of Intel® Active Management Technology (Intel® AMT) is just like any wireless connection; it is not an automatic initial connection process. However, there are several major differences between wired and wireless Intel AMT communication, including the following:
  • Wireless Intel AMT interfaces are disabled by default and must be enabled and configured with a wireless profile: friendly name, SSID, passwords, encryption, and authentication: at a minimum.
  • A wired interface is shared between the host OS and Intel AMT but can also be configured with two different IP addresses (example: Host OS with static IP and the wireless IP DHCP enabled). This is in contrast to the wireless interface, which must be DHCP enabled with the same IP address for both the OS and wireless AMT interfaces and the interface always controlled by the OS. The exception to this is when the host OS is deemed unavailable, in which case interface control is given to the Intel AMT firmware.

Key Differences between Wired and Wireless Intel® Active Management Technology Support

  • Default state -The wireless management interface is initially disabled and must be enabled in addition to creating and deploying the wireless profile. In contrast, wired connections are on by default.
  • Network type – Intel AMT supports only infrastructure network types, not ad hoc or peer-to-peer networks.
  • DHCP dependence - While wired Intel AMT connections support either DHCP or static IP assignment, a wireless connection requires DHCP, and it will share its IP with the host OS.
  • Microsoft Active Directory* integration - 802.1x wireless authentication requires Active Directory integration with the Intel® Setup and Configuration Software (Intel® SCS.)
  • OS control of packets - On the wireless connection, all traffic goes directly to the OS (which can forward any traffic for the Intel AMT wireless interface), unless the OS is off, failed, or in a sleep state. In those cases, manageability traffic is managed directly by Intel AMT, which means that when the host returns to s0 or the OS wireless driver is restarted, Intel AMT will return control to the host. This affects all remote connections to Intel AMT, including IDE-R and KVM. 
  • Wired-only Intel AMT features are not supported on wireless-only platforms - Heuristic Policies, Auto-Sync of IP Addresses, Local Setup Directly to Admin Control Mode, 802.1x Profile Configuration.

Intel Active Management Technology Wireless Support Progression for Intel Active Management Technology 2.5 through 11

  • Intel AMT 2.5 and 2.6: Wireless is supported only when the OS is in a powered-on state (S0).
  • Intel AMT 4.0: Wireless is supported in all sleep states (sX) but depends on configuration settings (Note: Intel AMT 5.0 did not support wireless).
  • Intel AMT 6: Syncs Intel AMT and host OS wireless profiles.
  • Intel AMT 7.0: Wireless is supported and host-based configuration is available; however the remote configuration is not available over wireless.
  • Intel AMT 9.5: First release to support wireless-only platforms. USB provisioning is not supported on these devices.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
