Started this thread due to a bug when using Wifi on certain devices.
The issue is that wifi starts off normal but when it is called upon to stream or download it turns off.
This in turn causes the box to lock up and freeze and only unplugging power will restart the box.
Below are some links of the reports of the issue.
Try and be as precise as possible with the details of your Box as some of these
boxes have very similar to almost the same name.
