I've been having issues connecting to wifi access points, and I am wondering if the band is messing things up. How do I tell what band a wifi connection is using on the laptop if I don't have access to the router settings?

Option + Wifi Menu

Hold the Option key down and select your WiFi icon in the menu bar ( ⌥ + ).

Additional information in the menu includes “Channel:” and (5 GHz) or (2.4 GHz) for the current radio settings.

As seen in Yosemite:

Wireless Diagnostics.app

You can get even more information from System Information. But I usually open the Wireless Diagnostics app (in Applications > Utilities folder). Choose Window > Info to get more detailed WiFi networking or scan for better channels, check for interference, etc.

I use iStumbler, which specifies the frequency.
