Hi, 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. Thanks, Weiran.
