USB3-E1000 Ethernet connection doesn't work since I loaded Yosemite (10-10)

Could not find a driver to download that’s any newer than for Mavericks. Is there one available for Yosemite - or is one being developed as we speak.

Bought this a few weeks ago. It enabled me to connect both an external monitor AND an ethernet cable to my Macbook Air. Sadly, after upgrading to the Mavericks OS X 10-10 the pluggable device no longer allows me to do that (it doesn’t work anymore).

I took a large jump from elated to disappointed in one fell swoop.

Hello Kenneth,

I am sorry to hear this. There is a 10.10 compatible driver for this Ethernet adpater available ->….

*BUT* it is best practice to uninstall drivers before performing a major upgrade and to install the newest version after the upgrade.

There have also been cases where customers complained about not having any network functionality after the upgrade which is a different problem all together. Please test to see if your WiFi connection works. If so, we can rule out this problem.

Then I would recommend the following (please make sure to read this carefully, you do not want to accidentally delete the wrong extension or make a mistake when performing these steps, I cannot take responsibility for things going wrong here):

  1. Disconnect Ethernet adapter form computer

  2. Take a look at System Information > Software > Extensions and look for an instance labeled “AX88179_798A” and select it and take a look at the “Location path” (as an example, in Mavericks it was /Library/Extensions/AX88179_178A.kext)

  3. Open your Terminal and run the following command -> sudo kextunload /path ofwherever/thextensionis/NAME_OF_THE_KEXT_FILE.kext (note this is the path shown in system information in step 1). Now you have unloaded this extension.

  4. Reboot

  5. Download the newest driver from here ->… and install it

  6. Connect Ethernet adapter and test

Please let me know if this yields any results.
