I have a Dell OptiPlex 9010 Desktop computer with windows 10 Pro. I have had no issues until now.
I have internet via a dish on roof and cable thru wall that goes to Ethernet adaptor with power to surge protector and Belkin Router.
I have Ethernet cable from router to desktop computer (Dell ). I wifi with Laptops off of this router with no problems. Now my Dell
Desktop will not go online. It says Ethernet driver missing. I have installed new driver off of Dell website and still have the same issue.

NE 1 know what to do or do I have to get a diff. Ethernet Card?

Thanks in advance
