If you plug one of our Plugable USB2-E1000 USB 2.0 to Gigabit Ethernet Adapters or others based on the ASIX 88178 chipset into an Mac Lion system, Apple will match it with the Apple Gigabit Ethernet driver that’s included in Lion.
But things often fail on non-Apple adapters in a confusing way: it will show as “Connected” in the Network control panel, but connections out won’t work — you’ll notice it has a self-assigned IP address (169.*), no router, and no DNS server. It looks something like this:
Fortunately, ASIX has an updated driver which works on Lion 10.7 (and older versions). Note that if you had done this before upgrading to Lion, your old driver may be 32-bit. Lion moves all systems to a 64-bit kernel, so in the case of a Lion upgrade, you may have to uninstall the old driver (uninstaller included in the driver package), and follow the steps below to get ASIX’s latest driver.
If you’re downlading with Safari, look for the Download folder the Lion has in your Dock by default. Click on that to bring up recent downloads, which looks like this:
Open that folder, then click on the “.dmg” to open the ASIX driver installer disk image.
The image then shows up on the left side of the window, below your other drives, called “DISK IMAGE”. Click on this to open the image, then click on the installer (the icon with the package opening).
You’re finally out of Lion’s folders and into the installer proper.
The ASIX 88178 driver isn’t big (254K)
You will be prompted to let the driver install.
A reboot is required for the newly installed driver to be active.
After the reboot, if you open the Network control panel, you should now see “Connected”, but now also with a properly assigned IP address, DNS, etc.
If that’s not the case (or something goes awry later), it’s common on Mac OS X to need a fresh interface for the adapter, which you can create via the network control panel (this creates a new, clean configuration for an adapter). See the ASIX Mac installation guide for details.
And once you have that automatically assigned IP address, you should be done – open Safari and enjoy!
