@@ -45,7 +47,9 @@ If a connection cannot be established over USB then check the following:
 * Make sure the OTG adapter is plugged into the Android device and not the Oscilloscope. If using a Micro-USB adaptor it is possible to get this the wrong way around.
 * Do not use other adapters between the Android device and oscilloscope. For example, using a Type-C to Micro USB adapter between the OTG adapter and phone will prevent
 a connection being established.
+* If the Wi-Fi LED is blinking, unplug the OTG adapter from the Android device and then try again.
 * Ensure the correct firmware has been installed. You can do this by repeating steps 2 and 3.
+* Check that the USB cable is not a 'power-only' cable.
