Hi all.
Overall I've been happy with the QBox until I plugged the the device's USB connector into my PC's USB which is next to the Ethernet port.
It would seem that the power brick isn't earthed and is using the Ethernet port to earth itself, causing the Ethernet connector, VDSL modem and router to drop connection until the device is unplugged.
I've been using the device via a travel adapter to convert it to UK 3 pin plug, I've just this moment replaced the 2 pin connector with a UK 3 Pin and the problem still exists!
Any advice would be greatly appreciated.
