Anyone know how I can tell for sure whether my MacBook Pro is
running at
802.11n speed? I do have the latest Airport Extreme and MacBook
Pro, so I
assume so, but wouldn't mind knowing for sure. Same question for my
Apple
TV.
Also, how can I tell whether Apple definitely installed the faster
(7,200rpm) hard drive in my MacBook Pro? I checked System Profiler,
but it
doesn't seem to mention 7,200 rpm anywhere.

Is there are firmware upgrade to bring an Airport 802.11g card up
to 802.11n or is there a hardware implication as well?

Hi Severin,
It is a hardware difference. The Macs that can be upgraded by the
"enabler" program already have 802.11n hardware.
Apple disabled the n-speed features (for reasons only Apple knows).
This program updates the card's firmware, to re-enable the features.
If your Mac doesn't have one of these cards, then you'll require new
hardware to use 802.11n. It is unlikely you'll be able to get an
upgrade card to replace Apple's AirPort card, but you should
(eventually, if not now) be able to buy a third-party device that can
attach to a PCI, PCIe, USB, FireWire, or Ethernet port to provide
this capability.
On searching MacInTouch:
What makes 'n' different from a, b & g. Short explanation...three
things:
- multiple radios & antennae ~ 802.11n uses MIMO (multiple-in,
multiple-out) antenna arrays that allow for 'steered' beams and the
ability to focuse more energy at a specific location. In some cases,
Apple is currently shipping units that can be configured with as many
as three antennae
- more spectrum, taking advantage of not only 2.4GHz, but also, 5GHz
bands
- improved packaging data efficiency via less overhead than previous
methods could be designed for at the time.

Ronni
