Unfortunately the line test has failed to complete, due to 100% packet loss. This means that we were unable to connect to your computer via a ping request. The most likely cause of this problems is firewall software that is set to block ping requests. This firewall software may be installed on your computer, or built into your router (if you use a router to connect to the internet).
And yes, I do use a router for my laptop which is the computer I've been trying this on. So it's connected wirelessly.
