This happened to me about 4 months ago. I called Time Warner, they had me run a traceroute and all, told me that it was my computer, my modem was working fine.
The next day, it started working again.
Now over the weekend, its happening again.
I am connected at 12 MBps, but my browsers won't let me online. I can't figure it out.
I have Road Runner with a wireless modem/router, but the router is connected to my PC via usb.
