How to determine whether I'm using 2.4GHz or 5GHz Channel?

    I've been curious lately which wifi channel my '14 rMBP 13" is using. I've set the Airport Time Capsule for Automatic 2.4GHz and 5GHz channels. How do I determine which channel I'm connected to? I'm located about 20 feet from the Airport but have it located behind my television. I'm also curious if that obstruction is keeping the rMBP from using the 5GHz channel.

    Hold Alt(option) and left click on the wifi icon.

    Under "Channel" you'll find the information you're looking for. It's basically the equivalent of doing the above, but this is a much easier way to do it and the information is more readable.

    For example, in my case it says:
    Channel: 36 (5 GHz, 40 MHz)

    Additional advice, in addition to the previous advice... :D

    I named my two networks - "Fast" for the 2.4GHz network, and "Faster" for the 5GHz network. I prioritize the network in the Network System Preference Pane. I also set the Preference to require an Administrator's password to change networks. Now, I KNOW which frequency my Mac is connecting to...
