I've had a (mostly) steady internet connection for the past two months. For the last hour, however, my connectivity has been dropping every 10 minutes or so, and must be reset.

So far, I've always been able to fix the issue by running Windows network diagnostics (On Windows 7 64 bit), but the lack of constant internet is making it a pain to try and stream video, download games through steam, etc.

Windows always reports a fix by "Resetting the Local Area Connector", telling me: Default Gateway Not Available.

What's going on? Is the trouble on my end, or with my ISP? (Timewarner Cable)

Things I've Tried:

  • Reinstalling the motherboard's LAN drivers
  • Manually setting a default gateway (gets cleared, reverts to default settings)
  • Unplugged (Hard Reset) the router
  • Unplugged / replugged ethernet cable.

Did you restart the router/modem? Do a hard reset of the device? – Moab Sep 26 '12 at 1:19
@moab Yes, I did. No router, just straight from the modem. – Raven Dreamer Sep 26 '12 at 1:24
Is it possible that your DHCP lease is expiring and/or being invalidated? Check you IP address network information by doing an 'ipconfig' – Art Sep 26 '12 at 1:36
@Art What should I be looking for? – Raven Dreamer Sep 26 '12 at 1:41
Take a look at your IP Address and default gateway when the internet connection is not working, and then check again after 'fixing' it. – Art Sep 26 '12 at 2:05

Given that this has not repeated itself, and lasted almost exactly two hours, I'm going to conclude that this was a problem on the ISP's end.

Thanks a bunch for the heads up, Timewarner! :/
