Just a few days ago, the general public was able to download Apple’s newest desktop operating system: OS X El Capitan.

For those of us wanting to find out the best wireless channel to use for our network, you have to trawl through a few settings just like with OS X Mavericks and Yosemite. In this short guide, we’ll go through the 3 simple steps you need to take to find the OS X Wi-Fi scanner and identify the best wireless channel for your network.

Step 1: Open Wireless Diagnostics

On your Mac’s menu bar you’ll find the Wi-Fi icon. Push down the Option key ⌥ (next to the CTRL key) on your keyboard and click the icon. You should then see a long menu, and near the top you’ll see a menu item called ‘Open Wireless Diagnostics’. Click on that.

Step 2: Click on “Scan”

Step 3: Find and use the best Wi-Fi channel for you!

After opening up the ‘Scan’ window, there will be a summary of your current wireless channels and a suggestion for which ones you should be using.

Once you have that information, just log into your router and adjust your wireless channel settings there!
