Say I'm connected to a particular access point and that I'm using Windows 10 Pro. How would I be able to find out if the access point is using 2.4GHz or 5GHz?

In windows 10 (once you connect) you just go to Settings/Netowrk&Internet/click on the SSID name and scroll down to properties. It tells you the Band, protocol, channel, security type, and all that good stuff.

update: Only on windows 10 anniversary update and up

  • Doesn't work for me. Clicking on the SSID name just displays a "Disconnect" button. There is no "Properties" section or button anywhere to be seen. – Tilman Schmidt Aug 28 '16 at 20:48
  • Windows 10? Mine shows it. Just checked again. It even shows a "properties" if I click on the SSID down in the taskbar. I guess I am running the preview version on this PC though... – jAce Aug 29 '16 at 14:02
  • Mine is Windows 10 Pro, updated from Windows 7 Professional. German locale, but I'm sure I'd recognize any of the translations for "properties" Microsoft would come up with. (Although their German translations are often quite strange and inconsistent.) – Tilman Schmidt Aug 30 '16 at 22:26
  • I also don't have the SSID anywhere in the taskbar, just the WLAN icon which displays the SSID as mouseover. If I click on that I get the list of visible WLANs, with mine marked as "connected, secured", and if I click on that, the "disconnect" button appears, nothing else. At the bottom of the list is a link "network settings" and two buttons to switch off the WLAN or to switch to airplane mode. – Tilman Schmidt Aug 30 '16 at 22:33

    It is a "windows 10 anniversary update" feature. So it won't be on your PC till it's updated. Either Automatically by windows or manually by you. – jAce Aug 31 '16 at 21:19

    Upvoted. This worked for me on Win7. I had to look up the channel # in a table to see the GHz. Roundabout, but it worked. – RedDragonWebDesign May 2 at 22:18
  • yeah, for this purpose you need to look at Channel, but that is pretty darn indicative... in the US the 2GHz channels are 1-11 ... bigger numbers are 5GHz – Mike M Jun 17 at 13:48
