I've been using the Thunderbolt Ethernet adapter on my rMBP for a few months now and it was working fine, but a few weeks ago it started to stop working. It drops after about an hour or so the first time, but after a restart it may stop as quickly as a few minutes after booting it up. It still appears in Device Manager, but it loses its connection somehow and refuses to reconnect, even after unplugging/replugging both the cable and adapter individually and together. It works perfectly fine in OSX, though. It's becoming an issue, anyone have any ideas?
