Hi all, I own a mac pro and MacBook. Annoyingly I failed to purchase the wifi card when I bought the Mac Pro, and now I need one. From end of April onwards I will need wireless access, so I was thinking about I use an Airport Express and connect the Mac Pro to it through ethernet, then access the wifi network that way? I'd rather not have to drag my Mac Pro to a store (all the ones nearby seem to be miles from a road in middle of shopping centres - not fun to carry a Mac Pro containing 4 drives with critical data on them through town), and I don't believe Apple will sell just an upgrade kit. I looked for a USB wifi dongle with no luck. If I can use the Airport Express, could I use the USB port for an external drive for Time Machine that can be shared on the wifi network? Or at least for the Mac Pro (will allow me to put a HDD in another room and the ethernet cable from the AE just a few meters)? Thanks in advance. Oh yeh, ps: I am in the UK, so importing USB dongles from US isn't an option.
