Mountain Lion comes with a Wifi Scanner that is much better than you expected.

I tried out KisMAC at first, but couldn’t get it working. I hate reading their lengthy newbie guide.

Then I found a gem in Mountain Lion.

It turns out the Wi-Fi Diagnostics Tool (app) in Mountain Lion is updated with new features. It has added a wifi stumbler to discover the wifi nearbys (ssid, channel, protocols, etc).

To do a Wifi scan,

  1. Go to terminal and open open /System/Library/CoreServices/Wi-Fi\

  2. Go to File > Network Utilities

  3. Press Scan

Scan Results

That’s it. You got to see the details of wifi nearby.

PS: I was looking for a uncongested, clear channel to use.
