Might or might not be of use to anyone, but I was bored in work today so made up a diagram showing my network setup.
Its all working perfect, with the exception of the XBOX 360 which I won't get my grubby mits on till February
Gotta say, these homeplug devices are superb. True plug and play. Service I got from SolWise too was exceptional. 10/10 for service and product - highly recommended. Much more stable then WiFi.
