Hello all, this may be a stupid question but im going to ask anyway. I have an airport extreme that was connected via ethernet cable to my mac mini 1.83gig, (the one that doesnt have wirless), well I bought an 21.5in iMac (yay!!) and put the mini in my daughters room upstairs from the extreme. I dont want to buy 100ft of cat6 cable to run from downstairs to upstairs. I bought a wireless adapter from afterthemac but the thing doesnt stay connected and the software is buggy. Can I buy a refurbed express from the apple sight and connect it via ethernet cable directly to the mini? Or should I just run the cat6 ethernet cable? I would like to keep the speed as fast as possible for my daughter, thanks for reading.
