I have a desktop hooked directly to a Motorola SB5101cable modem through USB at the same time I've connected a laptop directly to the cable modem through the ethernet port and I was getting a limited or no connectivity message on the laptop, checked the IP address and it was invalid so I did ipconfig /release and then ipconfig /renew and it said it was unable to renew address. Could this be because my desktop was connected to the internet at the same time?
 
It could be a possibility that the modem can only do USB or Ethernet and not both at the same time.
 
DHCP server down? Release/renew should do it otherwise.

Cable modems generally have a http webpage that you can go to an IP address for. That would have logs telling you whats going on. It may not be allowing 2 devices to connect.
 
A question - Why'd you create an entirely new thread about your problem?
 
You can only use one or the other regarding the USB or the ethernet. It's a modem, not a router. If you want to hook up more than one system to the modem, the easiest way is with a router.

That is why you are getting a network connectivity error and you can't renew the IP address. The modem is already in use on another system and that system has the IP from the modem.

 
There's an easy way to resolve this. If the desktop is connected to the modem via USB, then use the desktop's Ethernet port to hook the laptop and desktop together (you'll need a crossover cable, not a straight-thru cable). Enable Internet connection sharing on the desktop and you're done.
