CPU usage on connectionLost

[Lapo]

Hi, at the moment we have no news because we were not able to reproduce the problem.

As regards this:

I haven't found a way to test on the emulator, sorry. There's no WiFi setting and the button in the developer tools doesn't seem to work properly for me.

I think you can turn off the emulator's wifi by shutting down the computer's wifi for a moment.
