My partner and I have just moved house and we're waiting for our internet to be connected. We're living in a group of units and as you'd expect there are numerous WiFi networks, all secured... or so I thought.
The other day I was using my phone as a wifi hotspot and my partners phone was connected to it (I had more data allowance). I turned off the hotspot and waited for her streaming music to cut out... and waited... and waited. I was becoming more and more amazed by how much of the song was buffered. I went to check what was going on and noticed her phone had somehow connected to an apparently secured WiFi network. The streaming service continued uninterrupted.
I thought, that's really odd, but hey, maybe we can mooch off the neighbours until our connection comes online. I tried my own phone and laptop... both were prompted for passwords and unable to connect.
How on earth can this have happened? We can connect and disconnect to this secure WiFi as we please, but only on my partners phone. My only guess is that by pure coincidence our neighbour pressed the WPS button around the same time, but that seems ridiculously unlikely.
How could my partners phone have connected to this secure WiFi network?
