direct connect between computer and cable modem

[carp5000]

I am trying to connect my laptop directly to the Netgear CM1000 cable modem and have set a static IP of 192.168.100.2 with a gateway of the netgear IP address (and the auto-filled subnet mask, but it cannot connect.  What am I doing wrong?

Don't set a static IP on the PC. Leave it at Auto Obtain. 

Power OFF the modem for 30 seconds after you connect the PC to the WAN port. Then back ON. Give 2 minutes then check for internet access. PC will have a Public IP address. Check for internet access.
