You should be able to get that info from comcast although I have no idea why just resetting the modem isn't working. If DHCP is enabled under your network connections Ipv4> properties it should be working.

Did you try the hard reset of your modem? Your modems IP should be your gateway address.

Besides no gateway, that IP address is wrong. So yes it appears that your computer is not "DHCPing" it's network settings from the router.

You computer must get an IP address from somewhere. You said you "unhooked a router"? If so was that were the computer was getting it's address from before?

Well if you just reinstalled than than DHCP should be enabled by default. Dynamic Host Configuration Protocol - Wikipedia, the free encyclopedia But since you did that, reinstall, did you do a hard reset of the modem. Because you should be able to connect without doing anything else. Using a paperclip or pen hold down that button for about 10 seconds. The snip I attached is just an example not specific to your modem but the ideas the same.

There should be one they all have one. It's recessed beneath the back plate. There should be a hole there. It's not labeled on the motorola's. But for future reference on the DHCP goto the Control Panel and select Network and Sharing Center/Change Adapter settings and right click Local Area Connection, select properties. Then highlight internet protocol version 4 and click the properties button. That should open a window and in the general tab should display Obtain an IP address automatically. That should be enabled by default. You'll see grayed out boxes where you could manually enter an IP address, but you don't want that. The advanced button will give you other options such as entering the Default gateway as well. This should all be done automatically by windows so reset the modem and plug it into the PC and you should be good to go.

I've run out of ideas since I can't physically see what's going on with your computer. Here's a link to that modems User guide maybe it'll help you. http://www.motorola.com/staticfiles/...er%20Guide.pdf If you can't view it I can email it to you or something.

You can also try to reset it by typing in a web browser(whichever one you're using Internet Explorer, Firefox, or Chrome) 192.168.100.1 and that well bring you to a GUI for the modem and you can reset it from there.

I know this might sound dumb, but make sure the StandBy button is OFF. You might switch it on/off to see if you get connected. While doing that you will need to type ipconfig /renew in the command prompt window.
