I bought a new router it works fine on everything, on the same day the internet stopped working only on the computer evverything else was working fine. The internet was connected but there was a yellow sign by the network symbol in windows 10. It randomly comes back on after 5 minutes. Now it happens every startup and i troubleshoot it and it says : "ethernet does not have a valid ip configuration-fixed". it comes back on as soon as troubleshooted. It still happens randomly and happens all the time on startup. How do i fix this?
