    I have what I think is a 2nd gen (100Mb) Airport Extreme connected to my late 2008 MacBook Pro. I can't seem to get it to connect with dual channels (for 300Mb), even when they're right next to each other.

    I have the Airport set to 5GHz N-only, is this 2nd gen Extreme not capable of dual channels? Or is it my MacBook Pro thats the limiting factor here? I've tried it with a 2009 MacBook Pro as well and I only get 150Mb right next to the router.

    No either 2.4 or 5ghz for your model!

    Sorry I don't mean dual band (2.4Ghz and 5Ghz), but use of wide channels to support two channels per connection to enable the 2x2 300Mb bonded mode (N is usually 150Mb).

    I'm just wonder if this is an Airport Extreme limitation (as I suspect) or one of the Airport card in my MacBook Pro.

    I think I just answered my own question:

    The WiFi chip in my MacBook Pro is the Broadcom BCM4322, which supports 2x2 (source).

    But according to Wikipedia only the dual-band Airport Extremes can do 2x2, so I guess its time to upgrade.
