In this video we show you easy ways on Microsoft Windows 10, Android, and Apple iPhone to tell if the WiFi networks around you are 2.4 or 5 gigahertz (GHz).

In January 2021, Xfinity began shifting their public WiFi hotspots to 5 Ghz only. This means computers with older 2.4 GHz-only WiFi devices will not be able to detect them. It may be time to upgrade your WiFi to a dual band 5 Ghz capable product.

If you already have a dual band WiFi receiver, such as the ALFA AWUS036ACH, or the forthcoming ALFA WiFi Camp Pro Dual Band edition, you will want to connect to 5 Ghz if it is available, as 5 Ghz usually offers faster speed and better performance. Some campgrounds offer both for example, but you may not always be able to tell by the network names alone which are 2.4 and which are 5.

We show you ways to determine if networks are 5 Ghz on a Microsoft Windows 10 PC via Windows properties and also a third party application called WiFiInfoView available for free download.

We also show you how to use the WiFi Analyzer app for Android phone, and the Airport Utility app for iPhone to do the same thing. If you have an older PC that may not be dual band, using a modern Android phone or iPhone to scan for nearby network information may be more beneficial since these devices have dual band WiFi capability already.
