I brought both the MBA and ethernet adapter to the Genius Bar today and lucked out on who helped me. The guy there figured it out very quickly based one something he's seen before. Create a new location in the Network preferences.

Plug the ethernet cord into the adapter, wait a second or two, then plug the adapter into the MBA. Open a page in Safari and keep refreshing it until it loads. It should recognize the adapter and get a network connection within a minute or two. This fix seems to be a one time thing - I didn't have to do this when I connected at home later.

He's seen problems with the default 'Automatic' location in the past on other models too. Perhaps it is something in the install process. Using a new location seems to resolve the problem.

If you really want a location named Automatic, delete the default one and rename your new location to Automatic. Message was edited by: anpwq. Apple Footer.
