  5. Select the “Wi-Fi Scan” tab, and select “Scan Now
  6. When finished, look at the bottom right for the best channels recommendations:
    • Best 2.4 GHz Channels (usually 802.11b/g)
    • Best 5 GHz Channels (usually 802.11a/n)

The screen shot above is an example of the best channels chosen are 2 and 3 for 2.4 GHz, and 149 and 157 for 5 GHz using the wireless channel scanner tool on Mac OS X.

When you go to change the Mac wireless channel, it will vary depending on the router manufacturer and the IP address used. Using a Netgear router with an IP of 192.168.1.1 as an example, simply point any web browser to that IP, log in using the router admin login (often admin/admin), and look for the “Channel” option, typically located within a “Wireless Settings” or “Broadcast Settings” preference region. Change the appropriate channels for each protocol, save settings, and the wireless scanner on Mac OS X will have done it’s job.
