Windows – My NIC keeps getting the same ip 169.254.x.x

adapteripnetworkingwindows 7

I have a strange issue with my network card in my pc.

My internal network adapter keeps getting an ip that does not come from the ADSL router's DHCP that I have connected to.

  • I have changed cable,
  • I have tried using a new router,
  • I have checked the automatic dhcp feature without any firewall and other strange setting on.
  • I have disabled and re-enabled the adapter.
  • I even inserted a new network adapter but even the new one is getting that same ip: 169.254.x.x.
  • I have disabled the ipv6 protocol and even put static ip in the range of my routers availability but even then I cannot open the router interface at 192.168.1.254.
  • I have un-installed all anti-virus agents and firewall services but keeps up the same!

My environment is Windows 7 Professional.

Let me mention that in the same problematic infrastructure of router/cable if i install a usb wifi dongle…works just fine! and the ip is correctly assigned with full adsl usage and web router access!

Does anyone have any idea what else to try?

Your address cannot begin 196.256 as the octets (numbers) range from 0-255. Perhaps you mean an IP address that begins 169.254. (If so, please edit your question to reflect reality.)

a 169.254 address is indicative that the PC couldn't get a address response from a DHCP server. Typically in a SoHo environment this would be the router.

If you want to check the settings on the router you are going to need to set a static IP address on your PC. Use an address in the range 192.168.1.10 - 192.168.1.250 (do not change the first three numbers as they must match your router's IP address). The netmask will be either "/24" or 255.255.255.0. You don't need a gateway but it would be the router's IP address. DNS likewise, or set it to 8.8.8.8 for now.

You should then be able to contact the router, ping 192.168.1.254 or open the router configuration page in your web browser.
