So I am trying to connect my desktop to my router via an Ethernet cable. When I plug the cable to my PC, it won't connect to my router. However when I plugged the cable to a laptop, it worked fine. I also went to check the Broadcom NetLink Gigabit Ethernet adapter in Device Manager and it has an error that says "This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)" Can anyone help?
