OK, one of my daughters have been using my ethernet cord which attaches to my laptop so she could skype. NOW, when I go to hardware devices, I have the yellow exclamation point with a NEW device named "network controller". No other network controller named on the list. Could it be that each time she unplugged my ethernet to use, then put back on MY laptop, this has caused my device to uninstall, or what? Should I try in install? Here's the sequence which shows in the windowCI\VEN_8086&DEV_4223&SUBSYS_10208086&REV_05\4&2FA23535&0&18F0
