I have a Vostro 200 with cable network connection via a router. A recent storm damaged the router, which I have now replaced with an identical one, but I cannot regain internet access, the connection is showing as "unidentified network". All our other computers using the new router are fine.
I have tried changing cables/ports and used the diagnose and repair option in the network and sharing centre, but no joy. The port on the back of the computer is flashing with a green and amber light, and the corresponding port on the router is also showing a light. The network adapter shows as working properly in Devise Manager.
I would be grateful for any suggestions for sorting this out.
That tells me that the Vostro may have gotten zapped. I once had 2 ports on a router get zapped but not the other 2. You just never know. And the cable modem which was separate and before the router did not get zapped.
It is not too expensive to buy a USB-Ethernet adapter or buy a special PCIe Ethernet card if you have room your PC case.
