Saw someone mention leaving the ethernet cable in might not allow a good reset because of the power draw from the ether cable. Another indicated you may have to wait five minutes with cable modem unplugged from the wall.
Maybe a bad/wrong ethernet cable. On linux you can use mii-tool -v to see if it has link signal.
Check the cable between the NIC and the modem. Make sure it's a patch cable (straight through connection) and NOT not a crossover cable. Look at the wires at each connector. If the same color is connected to the same pin at each end, then it's OK.
A crossover cable physically has some of the wirescrossed from one end to the other to allow the data to transmit/receive properly between devices. The orange, orange/white and the green, green/white wire are reversed on one end.
The difference between regular and crossover cables:

You didn't mention the type of modem. Some have routers built-in and have a setting that clones the MAC address of the NIC. Check the user manual.
Have you tried the "Network Connection Wizard"?
Click "Start", "Settings", "Control Panel", "Network Connections", and use the "Network Connection Wizard" to create a new connection. Connect to the internet through the LAN.
Also, click Start, Settings, Control Panel, Internet Options, click the "Connections: tab, click "LAN Settings..." button and uncheck "Automatically Detect Settings" and "Use Automatic configuration script", "OK", "Apply", "OK"
