Hi!
These past days I've been trying to connect my MiBoxS with the ethernet cable as I've done many times in the past but it's no working. I've tried using different cables and USB hubs but nothing works, occasionally it will appears as it is connected but it only lasts for a few seconds, I've tried the same hubs and cables with other devices and they work perfectly. As I've said before I've done this many times before and until now it worked. I could really use some help using wi-fi with the MiBox is useless.
Disable wifi.
Also, are you trying to connect to a VPN as well?
