That update was present in the thunderbolt software u This adapter requires an update to the AppleBCM5701Ethernet plugin to work. That update was present in the thunderbolt software update 1.2 package. Said update was pulled from the automatic update list due to it crashing non-thunderbolt systems such as old macbook pros. I haven't read a report of any problems for us macbook air users, and it works great on my 2011 macbook air. If you're lucky enough to have grabbed a copy of the update from apple's KB article before it was pulled from there as well, you should be able to use the adapter. Presumably apple will fix this big error in a day or so with a newer thunderbolt update.

    If you know what you're doing, you could always backup your IONetworkingFamily kext before applying the update, and then restore just that kext it if your system crashes from the update.

    Nice performance with this dongle - I get 900Mbps throughput. Driver (and broadcom's specs) indicate jumbo frame support, but I haven't tried it. Jumbo frames not really necessary IMO since the CPU is beefy enough to handle high packet/second data rates.

    Finally a cheap way to get data on&off a macbook air at speeds above USB 2.

  • Tbolt to Gigabit adapter not compatible w cable modem

TWC is my ISP, I use a NetGear C3000 cable modem/router. My MacBook Pro is 4 weeks old. Wifi works lightning fast. However, when I use an ethernet cable and the Tbolt to Gigabit adapter, content takes forever to load, and after three or four pages, won't load at all. MBP detects the ethernet conn and shows it's connected, but I can't browse. Apple, NetGear, and TWC all unable to solve.

I would play a few online games and my Ping would be higher than everyone else. I bought this adapter because it would be a direct internet connection to my computer and even though my Ping went down dramatically my internet connection while browsing the web got extremely choppy. Sometimes websites would not load or even take 3 minutes to load. When I disconnect the adapter, the internet would go back to normal and sites would load immediately. I don't know why but this adapter makes browsing the internet a hassle.
