Dell desktop running Win7 connected to fiber optic router via ethernet cable. Error message appeared after a reboot after a power outage.
1. I have tried different ports and different ethernet cables in case it is a physical malfunction. Amber lights on gigabit port still illuminated
2. Other devices are connecting to the router via WiFi with no problem.
3. I have tried rebooting the PC and the router.
4. Under Control Panel / Network Connections, I have three boxes:
(a) Broadband connection, Disconnected, WAN Miniport (PPPOE) (green checkmark)
(b) Local Area Connection, unidentified network, Intel (R) 82567LF-2 Gigabit Network Connection
(c) Local Area Connection 2, Network cable unplugged, TAP-Windows Adapter V9

IPCONFIG /ALL appears below:

Autoconfiguration IPv4 Address. . : 169.254.215.1(Preferred) means your computer is not talking to the DHCP server of your network.

Assuming your NIC is good, you could try "ipconfig /release" followed by "ipconfig /renew"

You could also try the network troubleshooting wizard by right clicking the network icon in the system tray and selecting troubleshoot problems.

There are some other things to do to test your NIC, but those 2 things are the quickest and easiest fixed and are usually the solution. Let us know how that works for you.

Sometimes resetting everything can work.

At administrator command line try: netsh int ip reset c:\resetlog.txt
