If you go to Control Panel > Network and Internet > Network and Sharing Center > Change Adapter Settings, then right click on your adapter, choose properties, go to Internet Protocol Version 4, Click Properties, your DNS settings are there. You can leave them blank, and TWC's DNS servers will work (I won't use them - they are extremely slow). I use any combination of:
1) Open DNS - 208.67.222.222 and 208.67.220.220
2) Google: 8.8.8.8 and 8.8.4.4

If you are using DHCP with your router, you need to renew the DHCP settings on your PC.
Open a command prompt.
Type "ipconfig /renew"
