I've recently moved a desktop from my study downstairs to serve as a HTPC. In the study, the PC was on a wired connection plugged directly into a Comcast-provided cable modem. Now that it's downstairs, it's wired to a router (which is wired to a non-Comcast-supplied cable modem) that has been working flawlessly to serve other wired devices (PS4) and several wireless devices. However, the moment I connect the ethernet cable from the PC to the router, all internet access is lost for every device on the network. Similarly, as soon as the PC is disconnected, internet access is restored immediately.
Releasing and renewing the IP address restores internet access for an inconsistent, but short, amount of time before eventually throwing the same DNS errors. I've updated my ethernet controller's drivers, disabled and re-enabled the device, and have tried a winsock reset--all with no luck, or a short-lived connection.
If anyone has any suggestions, I'd be very grateful.
