#WIFI SCANNER FOR MAC INSTALL#
You could use a graphical app like Wifi Radar for this on Linux, but you’d have to install it first. The “Best 2.4 GHz Channels” and “Best 5 GHz” Channels” fields will recommend the ideal Wi-Fi channels you should be using on your router. Select the Wi-Fi Scan tab and click Scan Now. Instead, click the Window menu and select Utilities. To access it, hold the Option key and click the Wi-Fi icon on the menu bar at the top of your screen. Here, we can see that channel 6 looks a bit cluttered - we might want to switch to channel 1 instead.īelieve it or not, macOS actually has this feature integrated. Launch the tool, locate the Channel header, and click it to sort by Wi-Fi channel. We liked NIrSoft’s WifiInfoView instead - its simple interface does the job and it doesn’t need any installation. Xirrus Wi-Fi Inspector is very powerful, but it’s a bit overkill for this. You probably don’t want to pay $20 just to figure out which Wi-Fi channel is ideal, so use a free tool instead. We previously recommended inSSIDer for this on Windows, but it’s become paid software. Channels 1, 6, and 11 are the most frequently used for 2.4 GHz Wi-Fi, and these three are the only ones that don’t overlap with each other.

Note that Wi-Fi channels overlap with nearby channels.
