Ether. Status window shows 100.0 Mbps. On laptop with working gig nic, it shows Gbps. Asus says it is supposed to come with a gig nic. So why isn't it acting like it. And why won't it allow an off the shelf nic, installed in the PCIE slot run like a gig nic? That's my puzzle.What is telling you "10/100" ?
