    Hi all.

    My 13" has a max transmit rate of 300 on the 5ghz band, whereas my other machines have a 450 transmit rate reporting.

    Can anyone tell me if they are seeing the 450 on their new machine (hold down option and click the wifi icon on menu). If so, can anyone advise why I would not be getting it?

    Detailed approaches are appreciated. (It is a new APX and Time Capsule) btw and both are working fine with MBP's @ 450 transmit rate.

    My Mac Mini also has a transmit rate of 300 with the new Time Capsule 2TB. They stand right next to each other.

    Looking at the teardown, http://www.ifixit.com/Teardown/MacBook-Air-13-Inch-Mid-2012-Teardown/9457/2

    I only see 2 antennas, so I am guessing this isn't a 3 stream device. Also, the macbook pro press release specifically mentions 3 stream, while the air's doesn't.

    Well that explains that.
    Strange, thought it had 3 antennas.

    Thanks for the assistance, and tests.

    Yeah, its disappointing. I didn't check until I saw this thread. I have about 20-25 2.4ghz ACs near my apartment, but I am the only 5GHz one. Would have been nice to get the extra transfer speed.
