Question: Does it work with windows 8?
Document: Good, works, but does not (yet) work with OS X 10.8 (Mountain Lion). The issue is that Asix has not made drivers for it yet.
Despite the reviews that drivers could be downloaded I followed the advice here and on other forums and none of the drivers worked. If you are buying this for a MBA or for a computer running OSX 10.7 or 10.8 look elsewhere. There seems to be no available drivers that work.
Might work for a windows system but did not work for OS X. The company that sold it handled it very well. Credited my money.
I purchased this adapter so that I could test network connectivity at work. The Adapter came with a cd containing old drivers that did not work with my macbook air. I checked the manufatures website at asix.com and found the updated driver I needed for it to run on OS 10.8 and so far it is working great! It has a blue led that lights up through the white plastic to tell you its linked.
I bought this adapter elsewhere and it would not work. Used included drivers as well as one from windows update, no luck. If it does not work use this driver. Remove the space before digitus in the link. [...]Worked instantly.Using Win7 X64. The link says will work on Mac as well. Can't confirm that.
I bought the USB adapter for my Macbook Air which I have converted into a Windows Machine and use it for my work (Web and Application development). I wanted to be on my LAN network at office because the WiFi reception was poor and there are network file transfers that required LAN network. I use my thunderbolt for external display so I had to resort to an USB Ethernet adapter.
Bought this to use on my mac book air, don't plan on running windows or lennox on your machine if you want this to work. I have spent probably 4-5 hours working out every little problem with this, countless driver downloads, mounting and unmounting, completely deleting drivers&#8230;.. Worked great on IOSX but how does it not work for my stock build of win7&#8230;.
I bought this adapter for my 2012 Macbook Air. It appears to work, but never picks up an IP address. I have tried several different drivers listed in the reviews here on Amazon, as well as the driver disk the product came with to no avail. It does the exact same thing under Windows 7 (tried it on 2 different Windows PCs). For the price, it's probably not worth returning. I had high hopes for this item, but it didn't work out in the end.
The flavor I received in the mail had the model # KY-LAN772BL. After tinkering around with drivers from the manufacturing web site (SYBAUSA) which did not work on my MBA 2011 13, I decided to pop the adapter into a windows netbook and it installed as a ASIX AX8872B driver. A google search later, found the Mac OSX Lion 10.7 driver, downloaded, installed and rebooted and my MBA recognized it.So far, no complaints.
This adapter works great with the new macbook air 11" (2010 model). I use Windows 7 64-bit on the macbook air and it was simple to get to work.In Windows simply plug this adapter in and it automatically installs the adapter from Windows Update, no need to reboot.In OSX you need to fiddle a bit with the install disc and manually go to the directory (noted above in another review) and run the package included, then reboot the machine.
Answer: I have two of these.  I have plugged them into three Windows 8.1 computers.  All thee recognize the device and download the drivers automatically, but return the error "this device cannot start (code 10)."  Thus, I am sad to say, No.I would note that both work just fine on the Windows 7 and Vista machines here.
