click on the 1st result.

Done. Nothing happens.

click start, in the start search box, type cmd and press enter.
in the black window, type ipconfig and tell me what's your ipv4 address and default gateway.

As said by Ken, 169.254.xx.xx is a bad ip address which is auto-generated by the OS when your router fails to give ip address to the pc. This time, click start and in the start search box, type cmd, then right click on cmd and click Run as Administrator, now in the black window, type netsh reset winsock catalog and press Enter, Restart the pc. If this doesn't work, try a system restore. or else, a clean install.

But a 169.254.xx.xx ip problem may not be solved bu updating the NIC driver. What i could also recommend is if you are using a modem to connect to internet, then unplug the ethernet cable from the compuer and turn off the modem, wait for 5 mins and turn it back on and then press the small RESET button on the modem. (This may work.) Then restart your computer and reconnect the ethernet cable to pc. Fingers Crossed.

The only issue with this is that any specific router settings adjusted by the IP (like PPPoE settings) go out the windows...

I have an old desktop that used to do this in XP...I updated to the latest drivers and it fixed it. Was it luck? More than likely but all possible fixes might be needed for this issue

You can call it as luck but what i have noticed with my past experience is whenever you have this ip address, the only things you can try to fix it is:
1: Release and renew ip address.
ipconfig /release and ipconfig /renew in an elevated command prompt.
2: clear the winsock catalog by netsh winsock reset calatog command.
3: Reset the ISP modem.
4: Do a system restore.
If the above steps doesn't work, do a clean install.
