Was the modem plugged into your PC ethernet directly, or into a router?If it was plugged into your PC directly, check the TCP/IP settings on your network card (Control Panel -> Network -> Local Area Connection -> Properties -> Internet Protocol TCP/IP -> Properties)Make sure ''Obtain IP automatically'' and ''Obtain DNS automatically'' are selected.If theres a router involved, you'll need to check the configuration of that.
This is a common problem I experienced with Time Warner all the time. Unplug everything and plug it back in. Your trying to reset your connection. If that doesn't work call Time Warner.
You may need to configure your router so that you can run the new ISP.

both is on auto. im not using a router pc conected directly to modem
So as a test, plug in the modem to your Ethernet port, open a command prompt and type ''ipconfig.'' What do you see?BTW, lots of software and hardware config issues can keep the connection from functioning properly with your PC. These usually aren't a factor with a router. If you have one, I would also try hooking it up to your modem and PC just to see.
chefkwt hx for trying to help my problem. ipconfig dpnt work cuz i have low or no conectivity lol i have a 0.0.0.0.0 ip guess im stuck with usb conection unless i buy a pci nic card
Well, it means your modem and PC aren't connecting properly. Could be caused by a bad cable or a bad NIC on either your PC or the modem.
Call them up, DHCP is probably not working.
