yosemite - belkin thunderbolt express dock not working

Yep, I have exactly this. Late 2011 MBP, everything was working fine, upgraded to Yosemite. Dock worked badly for a short while (10 mins to access a file on USB3 drive) then stopped being recognised altogether, ... Anyone???

I see 10.10.1 didn't fix this.

This been bugging me all day, and found a fix.... Unplugged Thunderbolt Dock ; Deleted my current "Location" in Network Preferences ; Added a new "Location" ; Reconnected Thunderbolt Dock ; voilà... 🙂

I've tried all of the above (including rebooting the MBP and power cycling the Dock) and continue with the same symptom. Curious if anyone else hasn't been able to resolve it with MBP19's solution?!?

Make sure you have a Broadcom NetXtreme Gigabit Ethernet controller 2 in your Network preferences. Add one if its missing. That fixed it for me.

Thank you @jamsden! That took care of it. I'm so grateful for what networking enables!

Jamsden's solution of adding a "Broadcom NetXtreme Gigabit Ethernet Controller" under System Preferences/Network/[left hand panel] worked well for me.

The other "Add Service" options, "Thunderbolt Bridge", "Thunderbolt 1", and "Thunderbolt FireWire", didn't seem to do anything useful.

I used the same panel's gear or config pulldown menu to rename the "Broadcom NetXtreme Gigabit Ethernet Controller" service to "Belkin Dock" to be more recognizable.

Thanks Jamsden!

I just purchased Belkin Thunderbolt Dock (the first model, not thunderbolt 2) and ethernet is not working with MacBook Pro 15" Late 2013 running Yosemite (10.10.2). I have tried everything but it still doesn't work. What i did was:

1) disconnected the dock from the computer

2) created a new network "Location" from the Network preferences under System Preferences

3) deleted all automatically suggested network connections for my new "Location"

4) connected Belkin Thunderbolt Dock back to the computer

5) created a "new service" for my new "Location" by pressing "+" and selected "Broadcom NetXtreme Gigabit Ethernet Controller" from the "Interface" drop down menu

6) after that it takes few seconds and this "new service" finds IP address and shows green light and connection "Status" is "Connected"
7) despite the green light the network doesn't work

I have also restarted and unplugged cables etc. but network just doesn't work. Any ideas?

BR,

Timo

I too had this problem and just figured it out. Jamsden is correct that you need Broadcom NetXtreme Gigabit Ethernet controller set up in your network settings. That seems to work for some people, but that alone didn't work for me.

I had to adjust the DNS settings to our network's DNS server. To do that, I went in to my original settings, selected the Thunderbolt Ethernet, then hit the Advanced button at the bottom. At the top, select the DNS tab. Write down your DNS settings (I had 2 entries).

Go back to the Broadcom NetXtreme Gigabit Ethernet controller that you added (or which may already exist), and be sure it has the same DNS settings. That fixed it for me. I'm lucky I thought of that - not sure why I did!

If you are not sure how to add the Broadcom NetXtreme Gigabit Ethernet controller, one of the posts provides some instructions.

Good luck.

hi. How do you set up the Broadcom NetXtreme Gigabit Ethernet controller 2 in Network settings? I don't see it anywhere.

I advised someone with a new macbook pro to buy this dock, and we had the same problem with not being able to work the ethernet device. This time, adding the 'Broadcom NetXtreme Gigabit Ethernet' device was not an option.

We tried deleting the location, rebooting, unplugging, etc., but nothing seems to work.

Any hints?

Did the same thing. Deleted the location, set up a new one for Home and Bob's your uncle the ethernet connection via the doc came back... Thanks...
