Query: Useless on my NC400

This card makes the CPU usage go to and remain at 80% when it's plugged in. Research on the web tells me I'm not alone in this yet there is no known fix. I had problems with Netgear drivers years ago. I just tried the latest driver, months after buying the card (so they've had time to fix bugs) and it didn't change anything. Sluggish performance, constant calling out to DNS (other cards don't so why would this ione need to?)ZERO starts, unusable but not heavy enough to be a doorstop. I will never buy Netgear products again.
