I'm using Windows XP, and sometimes when my computer wakes up from sleep mode my built in Ethernet won't wake up from sleep. I have to restart my computer in order reconnect to the internet. My motherboard has onboard Ethernet, and it's an Epox 5VKMI. I have my the driver set to don't allow my computer to turn off this device to save power. Is windows ignoring this, or did they not implement this right. When this happens the driver has an exclamation mark on it, and under properties it says "this device cannot start". Does any one know what could be causing this.
