Ethernet connection dropping after reboot, just started today

Never had a wired connection drop happen before with the internet still working. Is this a windows issue, anyone else experiencing this? What could be the issue or issues? The fix is just unplug the ethernet from the back and plug it back in, seems to only do it a short time after rebooting (shut down to turning it on later) my computer. Any help or advice would be appreciated. This is a long cable from downstairs, we paid $50 to have installed by someone. Would rather avoid having to replace it if possible.
