Upgraded to 2.0.0 and got the same problem. Always used an ethernet cable which worked great before the upgrade. Now it returns 0.0.0.0 for ethernet connection. Tried wi-fi too and I was able to 'connect' to my home network, but yet the IP is apparently saved as 0.0.0.0, so its the same problem. Bought the box directly from Futeko in June 2016. I cannot use internet at all on my Q10 Pro right now.
After the upgrade I didn't change any setting. Just booted Kodi once and found out internet does not work, even though it says its connected to ethernet. As said, the IP always returns as 0.0.0.0.
I don't know yet how set my IP manually (static setting) which should resolve the issue for now.

Any tips to fix this?
