So I recently purchased a TRENDnet USB to 10/100Mbps Adapter TU2-ET100 and downloaded the drive installer from the website (downloaded 10.5 version since they didn't have a 10.8 version) as I don't have an external optical drive. After restarting my air, I hooked up the adapter and my air didn't even recognize it. Not sure if it's defective or incompatible. Any advice? At this point I think I'm planning on just opting for an apple adapter to avoid this mess. Would you recommend a Apple USB Ethernet Adapter or a Thunderbolt to Gigabit Ethernet Adapter?
