USB Ethernet Adaptor

I can replicate this on my new 13 MBA. I also have a new adapter and the ethernet connection fails by the MBA on either port ("Cable unplugged. Either the cable for USB Ethernet is not plugged in or the device at the other end is not responding.").

The adapter is recognized, and works, with my MacBook Pro. The other end of the ethernet cable is a DLink gigabit router running as a switch but it hasn't exhibited problems with USB adapters, including this one, in the past.

OK, when I applied my static settings, the cable was declared "connected". The issue here seems to be one of poor messaging from the network control panel. The cable is not unplugged, but it says that it is.

I'm getting the same problem with TWO different USB ethernet adapters that were known to be good before, using TWO different ethernet cables on TWO different Macs. The only common thread, aside from OS X 10.6.4, is the same Airport Extreme base station unit, but it works fine when connecting my MacBook Pro and my Mac Pro directly via the same network cables.

I just got the USB Ethernet Adapter today from my local Apple store... I got it pretty much solely for a faster transfer speed using Migration Assistant, versus the nearly five hours it would take for me to transfer 38+ Gb of stuff from my iMac to the Air via AirPort. Brought it home, plugged it in to both computers, and it said the transfer time would now be over FOURTEEN HOURS long! What the - ?! That was plugged into the right (display port and card reader side) USB port, and didn't try the left (power adapter side).

Plus, I didn't know if it would or not, but also tried to see if I could connect to the internet through the adapter, and couldn't either, as the USB port has it's own IP address or something.

So, I find the adapter pretty useless and without a point to having it, and will be returning it.

I'll be glad to finally have my Air up and running and all ready to go.

Did you buy the ethernet adapter along with the Mac? Is it an Apple USB to ethernet adapter?

When you plug the USB to ethernet adapter in does it ever show up in System Prefs - Network or in /dev/?

I have issues with this as well.

Brand new MacBookAir3,2 but the Apple USB Ethernet adapter was bought when I had the older MacBookAir2,1. Plugged it in, and nothing even shows up in System Preferences.

Disappointing.

yes it is a brandnew apple usb to ethernet adapter.
it worked with the macbook pro of my collegue, immediately it recognizes the adapter, but with my new macbook air it doesnt do anything. it says its not connected.
i did the "DHCP-lease renewing thing" and it didnt help.
what should i do?

But what if you need to use a static IP? Are you just screwed?

I'm having the same problem: cable is "disconnected" but it bloody well is not.

i am having the same problem with my ethernet adapter.
it is connected and i am sure everything is working but the system tells me that its not connected.

whats the solution for this problem??

This works for me on my new MBA and on my old Mac Pro. Thanks

Yeah, that's a weird fix and makes no sense, but for whatever reason it works.

Anyone filed a bug with Apple yet?

All this talk made me try mine today. I bought at a local store after getting my new MBA, but had never tried it.

Both sides worked just fine. In fact, writing this using the connection..
