The device lacks a correct IP address setup.
The device lacks a correct IP address setup.
I've attempted various solutions such as adjusting the control panel, resetting TCP/IP, clearing the Winsock catalog, releasing and renewing, restarting the router, and performing a full network reset. After a TCP/IP reset it worked briefly, then the Ethernet began to fail repeatedly. Troubleshooting indicated the default gateway wasn't available and was later fixed, but after a few minutes the message "ethernet doesnt have a valid ip config" reappeared. Help needed 
I refreshed my drivers, yet the device still drops every few seconds and comes back on, showing "unplugged" when disconnected.
