iOS users only – additional WiFi scan
Due to restrictions in iOS, there is an extra step required to provide full diagnostics.
Download and install the free app AirPort Utility from the App Store (Please do not start the test before completing step 2)
On your iPhone or iPad, go to Settings > Apps > AirPort Utility and enable Wi-Fi Scanner.
Open the AirPort Utility app and tap Wi-Fi Scan (top right). If the Wi-Fi Scan option is not visible, close the AirPort Utility app by swiping up from the bottom of the screen to the middle and holding, then swipe AirPort Utility to the top to remove it from the app drawer. Restart from step 1 and the option should appear.
Move the slider to set the duration to 20 seconds and then tap Scan.
When the scan completes, press the Share button (bottom left).
Select Share via Mail.
Email the scan to support@ask4.com including your ASK4 issue reference number and ASK4 Diagnostics Code in the subject line.
