Switching to a unique Wi-Fi channel can give you an instant speed boost. If you’re on a Mac and need help figuring out what the best channel is, we have got you covered.

Hold down the Option key and click on the Wi-Fi icon in the menu bar. Now click on Open Wireless Diagnostics from the dropdown, or just open Wireless Diagnostics via Spotlight search.

With the diagnostics dialog active, click on Window > Scan. This displays another dialog, in which you’ll find an overview of your connection on the left. The ideal channels you can use are listed in that summary.

You’ll need to tweak your router settings to switch to one of those recommended channels. To learn more about how channel switching works, read our guide to finding a unique wireless channel.

This method works on Mavericks, Yosemite, and El Capitan. While this should give you a noticeable boost in speed, there are other factors that might be causing a Wi-Fi slowdown, such as bad reception or interference.

Have you tried switching channels to boost Wi-Fi performance? Was there a noticeable difference in speeds after the tweak? We’d love to know in the comments!

    The admin page for the Verizon router NEXT GEN BHR3 REV I ACTIONTEC does not offer an option to pick different channels for 2.5 and 5g. You can only pick 1-11. At least, I cannot find any other option.
