You can share the results from the previous screen in several of the usual ways. Values above -40 are very strong, and should give rock-solid connections. For an iOS device to start looking at a connection, this needs to be -70 dBm or more, but once made, a connection can be maintained below -75. RSSI is the Received Signal Strength Indicator, a measure of the Wi-Fi signal strength of that transmitter. This gives the channel used and the RSSI values roughly every four seconds. You’ll then see each set of measurements made on that network over the scan period. To view further information, tap the network in which you’re interested. When the scan is complete, the app will show details of all the Wi-Fi networks which it has found. As scans take a fair bit of battery power, make yours as short as you need. Tap Wi-Fi Scan at the top right of the display. Unless you have an AirPort base station within range, its opening screen will stay almost blank. Turn it on (green), and exit Settings again. Inside you’ll find a switch for the Wi-Fi Scanner. Once it has installed, open Settings, and locate those for your new AirPort Utility app. Don’t worry – although that app is primarily intended to configure Apple’s obsolescent Wi-Fi base stations, this Wi-Fi scanner is good for any device from any manufacturer. In the iOS App Store, ‘purchase’ Apple’s free AirPort Utility. You don’t get much for free these days, but if you’ve got an iOS device, Apple can turn it into a natty mobile Wi-Fi scanner at no extra cost.
