Suddenly as I was working with my Dell Precision 7510 laptop with Windows 10 the network connection was lost. I can not connect via Ethernet or wireless. I ran the diagnostics which found no problems. The network adapters appear in Device manager but not in Network Connections. I have tried updating the drivers, the chipset driver and the BIOS. I have also tried uninstalling the adapters and rebooting but that did not help. I tried resetting the TCP/IP and got "resetting failed and access denied." I did run it as administrator.
