I'm going to buy this for my G5. http://www.amazon.com/gp/product/B0073JHRJ8/ref=gno_cart_title_1?ie=UTF8&psc=1&smid=A2CHLWLS0W5Q1 I've been sharing internet with my old eMac via Firewire since i can't find an extra Ethernet cable. I bough this a month ago thinking it had a built in internet card. Wow, was i mistaken. Has anybody had a problem such as this?
