when you are on Cable Internet with a "modem" only connected directly to the computer, what the ISP see is the computer's MAC Address (command prompt -> type ipconfig and hit enter).
put a router (which has it's own MAC Address) in-between and the ISP wont let you cause it sees the router not the computer.
check physical connection: cable modem -> router -> computer(hard wire for this troubleshooting)
access the d-link gui and locate the “Clone MAC Address" button (supposed to clone the computers MAC Address - verify if it's the same), save settings & reboot the router.

Shut down your computer, unplug the cable modem and the switch. Connect all three - computer to switch, switch to modem. Make sure that the ethernet cable between the router and the modem is in the router uplink port and that the computer is plugged into one of the four ports that look alike. Wait 30 seconds - plug in the modem. Wait another 30 seconds, plug in the router, wait another 30 seconds and boot the computer. Open a browser and see if you have internet access. If you still don't, then try to check the browser by typing 192.168.1.1 into the address bar of the browser. That should give you the browser sign in screen. The Linksys default is to leave the user name blank and type admin for the password. That should give you access to the router so you can check the settings. If this doesn't work, document carefully what happens and post again with your results and we'll try to go from there.

Cable modems bond to what they are plugged into, so you have the modem plugged into a computer and it is working fine. Then you want to unplug the ethernet cable from the computer and plug it into another device such as a netgear router. Then you find no matter what you do it will not work.
Now normally to break this bond to the computer so that it will bond with the router you would simply unplug the electrical power from the cable modem, wait for it to sync back up with your ISP's CMTS, power up your router which you would have connected via the internet or wan port, and you would be up and running.
You may have even did this with your Arris TM602. Why isn't your router pulling an IP address? The reason is simple, pulling the power cord did not really remove power since the modem has battery back up.
In order to make it release its bond to your computer, so it can bond with the router you need to either push the reset button on the back of the modem while still powered up or remove its battery pack while unplugged from power.
So try again, this time push reset on the modem. This question was posted in January so I am sure buttercup is all fine by now but maybe this will help someone else.
