By the way, you’re *supposed* to have the stock external Wifi antenna on the back of the unit. There’s a cable that runs from the front of the case where the Airport card resides. On the back of the case, there’s a little wireless antenna connector. There should have been a plastic antenna on the back of the unit, a T-shaped thing. Is yours missing? All of them came with this from the factory.
Got an antenna port, no antenna. The guy I got it from said it didn’t have AirPort installed so it didn’t come with one, and the folks at the Apple store said it didn’t need it. Plus it said on the Box “No antenna needed” and in the instruction manual they even do a Q&A:
Do I need to install an AirPort antenna?
No the antenna used by the AirPort extreme card is built in.
Well, I guess I HAVE to spend $110 total to get this bugger to connect Wireless. The sad thing is that I really don’t have ANY faith that for just $30 more it will finally work.
