I just moved my old rig, the UD3P, into my Wife's office on the other side of the house. She had been working on our MacBook Pro, which of course has an Airport wifi card. She was initially using the MBP's wifi connection, via an ethernet cable between the two computers. I started looking into adding a wifi card of some sort to the UD3P, when I got the idea that I might be able to just get an Airport Express, and connect it to the computer (via Ethernet cable) to be able to connect to our home network being broadcast from an Airport Extreme Base Station.
I was thinking, "Do these things even work that way?"
I read up on them on the Apple website, but didn't see anything mentioning this type of configuration. I called an Apple store, and the 'genius' I spoke with assured me that this would work.
So, I just went out and picked one up, at Best Buy. (for easy returnability if it didn't work) Reading through the documentation that came with it, it did not mention the possibility of using it this way. It only showed how to use it to connect the AE to one's modem, and connect using a computer with a wifi card, and how to connect it to speakers to be able to listen to iTunes over wifi.
I went ahead and hooked it up, at this point not expecting to be able to get it to work. After fiddling around in Airport Utility for a bit, I did finally get it to work.
Anyway, I was curious as to why I hadn't heard others using this as a solution for wireless on their Hackintoshes. I know it is one of the more expensive solutions, but, after contemplating spending $50+ on a solution that may or may not work after each Apple update, I decided that the few extra $ was money well spent to avoid any future compatibility headaches,
Just sharing my thoughts on this in case anyone wasn't aware that this is a possibility.
