I think I sorted the power problem but it made no difference! I didn't like the way the hub was back powering the mk809. I found an article about hubs doing this with the pi and people just snip the red wire either in the lead or in the hub, I peeled a little bit of the lead insulation back and snipped the red wire. It all works still as before but now neither device powers the other.
It still crashes as soon as I use the network though
I can however unplug the hub which tends to unfreeze the android stick.
I'm guessing either the hub or the ethernet adapter is not compatible but I'm not sure which!
The ethernet adapter is recognised by android and it obtains an IP etc, but as soon as anything really uses it it will only do a small amount before crashing.
I did try using the mk802 remote app so I could control it with my nexus and plug the ethernet adapter straight in but I can only get that to work over the wireless
So it stops working when I switch to ethernet, and I can't find it in the list of devices.
Any thoughts or suggestions for testing?
Edit forgot to mention that my connection is a 30mb Virgin media
