Continuously getting error: "The Default Gateway is Not Available"

[Cold_Finger]

My internet randomly dies, so I troubleshoot problems and continuously get "The Default Gateway is Not Available." It's fixed for one minute and then instantly dies again. I keep repeating the same pattern over and over, and I am SICK OF IT. I can't even play multiplayer games anymore.

Usually of the Checksum Offloads and such are enabled, but I was still getting the same problem when they were set to their default settings.

Does it only happen on your computer or all the computers in the house?

It only happens on my computer. Everyone else has a perfectly fine internet connection.

Sounds like the integrated ethernet chip is fried. Try and use a slotted Ethernet card and disable the onboard one.
