Here's the situation: I previously owned a G5 tower, I used a Hawking Technologies USB wifi adapter. It worked without any issues, that is, until the G5 died. I proceeded to buy a new Mac Pro back in July of this year. I decided to not add the wifi card to the new Mac Pro because I had spent $50 or so on the USB adapter a few months prior. Now, after a while of using the USB adapter with my new Mac Pro I've noticed a few things. I cannot be downloading large files and surf the internet at the same time. It also seems to be causing kernel panics and wake from sleep issues. I was told by the Apple sales rep that I'd be able to buy the card later if necessary, from what I can tell looking for it, he lied. So the question is, what other options are there for me? Would an Airport Express serve my needs? Is there a better USB adapter out there? Wifi is my only source for internet, being hardwired is not an option. Thanks for all suggestions.
