I have a Dell Inspiron 560 & the network adapter is not showing up in the device mgr. I have installed a new NIC controller & NIC driver from Dell with no luck. this is an intergrated NIC into the motherboard.....WHen I try to install the NIC controller software I get this message:
"the realtek network controller was not found. If Depp sleep mode is enable diconnect the cable"
Any suggestons? How can I further troubleshoot this?
