Ethernet Cable sometimes stops registering after I bring my computer out of sleep mode. How can I fix this? I can still use the wireless connection, but its terrible compared to the hard wire connection. Unplugging and plugging the ethernet cable back in does not help. If I reset the computer, the problem goes away temporarily until I go into sleep mode a few times. It seems to be random which instance of sleep mode will stop my computer from recognizing the ethernet cable. Help please.
