Questions & Answers

Q1: What changes are enabled with the new software made available by Intel?
A1: Intel has provided OEMs with updated Intel® PRO Network Connection Software that supports functionality improvements such as reducing system power and the resolution of issues involving operation of the RF hardware switch.

Q2: Is it true that users can't turn off the 802.11 radio in laptops based on Intel® Centrino™ mobile technology?
A2: This capability is fully supported in the software that is currently available for users of these laptops. Initial versions of these laptops did not fully support this capability under all circumstances when using the hardware switch. This issue has been resolved with the updated software.

Q3: How can a user be assured that the 802.11 radio on his/her Intel Centrino mobile technology-based laptop has been turned off?
A3: If the user wants to turn off the radio, he/she can do one of three things:

  1. Right-click (or double-click) on the on-screen Intel PROSet icon and choose the "disable" option
  2. Click on the "My Computer" icon and turn off the radio using commands available in the operating system. This is one of multiple ways to turn off the radio via the operating system.
  3. Some OEMs provide a radio switch, typically found on the side of systems. Users can disable the radio by turning this switch to the "off" position. This option requires that updated driver software be obtained from the PC manufacturer.


Q4: So is it impossible to turn off the 802.11 radio in laptops based on Intel Centrino mobile technology that initially shipped (i.e. in laptops that didn't contain the updated driver software)?
A4: No. Users of the initial systems can turn off the 802.11 radio by using commands in the operating system or by using the software switch provided on these systems. These options are available whether the updated driver software has been implemented or not.

Q5: Following FAA recommendations, most commercial airlines limit the use of Personal Electronic Devices (PEDs) which are enabled for radio frequency (RF) transmissions. Are users of laptops based on Intel Centrino mobile technology able to comply with these commercial airliner rules?
A5: Yes. Users can turn off the 802.11 radio on all laptops based on Intel Centrino mobile technology by using commands that are available in the operating system or by using the software switch. The updated driver software provides another avenue for turning off the radio via the hardware switch. Users are responsible for ensuring they comply with all airlines rules regarding use of PEDs in flight.

Q6: How is power consumption improved by using the updated software?
A6: Power consumption is improved when the Intel® PROSet application manages the Intel® PRO/Wireless 2100 LAN MiniPCI Adapter. The software update allows the hard disk drive to enter a low power state and the adapter to remain in a low power mode for a longer time.

Q7: How much is power consumption improved by using the updated software?
A7: Power consumption and improvements vary from platform to platform and is impacted by the various platform configurations.

Q8: Intel has promoted exhaustive validation as a key advantage of laptops based on Intel Centrino mobile technology. Why weren't these issues detected during your validation?
A8: Please ask Intel.
