How To Fix Lan Cable Not Working. If this works it means your router is faulty and it might be time for you to replace it. In that case you need to update network adapter driver.
If you test the cable and do not get good continuity than examine the connectors or patch panel port on each end. Look for the WiFi button and turn it off. Therefore to fix this issue updating the driver is recommended.
If it tests good than try the continuity again but this time with and through the patch cords on each end.
Switch to the Driver tab and then click on the Roll Back. You can do it both manually and automatically. So you can clean the port to see if it can fix the issue. Paste in your credentials and search for the Factory Reset option in Settings.
