How can I change IP address of my network card which have an odd IP address 169.254.57.200 which is not known by my router?

My router has IP addresses 192.168.0.2 - 168.168.0.254 I have problems with this computer contacting the network or Internet, I have tried to change with cmd ipconfig /release and /renew, but it did not work. Network card still has the same IP address...

Ideas or suggestions?

What’s the 168.168.0.254? The subnet mask? If so, did you set that? –  Synetech Feb 1 '12 at 6:13
    
@Synetech 192.168.0.2 - 254 is the DCHP scope. –  iglvzx Feb 1 '12 at 6:27
    
@iglvzx, and the 168.168.0? –  Synetech Feb 1 '12 at 6:39
    
@Synetech Oh, wow. I did not notice the extra 168. A typo most likely, but we do need some clarification. –  iglvzx Feb 1 '12 at 6:46
    
@iglvzx, um, look at it again: 192.168.0.2 - 168.168.0.254 > I did not notice the extra 168 There are two extra 168’s and an extra 0. > A typo most likely Actually, it’s not likely a typo; there are clearly two addresses, including a dash with spaces on either side. That would be the strangest typo ever. Also, check the original version of the question; that part is the same. –  Synetech Feb 1 '12 at 6:58

That IP looks like a random one as assigned by windows if you are unable to get a DHCP address. First make sure your router is functioning as a DHCP server and that your DHCP pool isn't full. If want to set an IP manually: go to the network and sharing center and on the left pane click on "change adapter settings". Right click the device that is connected and click properties, after selecting ipv4 settings click properties again. From here you can manually enter the IP address, make sure to set your gateway as your routers IP and DNS to either the router, local DNS server, or your preferred DNS provider like Google. You should be okay after doing this and have internet access assuming you didn't give your device an IP that is already in use.

More precisely, a link-local address. –  grawity Jan 19 '11 at 17:03
    
Thanks @grawity I couldn't remember the name for it. –  Kyle Jan 19 '11 at 17:04

To add to Kyle's point, the address 8.8.8.8 is a Google DNS server I use when I need to. It sounds like your router isn't functioning properly as a DHCP server.. you could login to your router's IP address (address is cmd > ipconfig > default gateway ip). Google the router's default username/password if you don't have it on hand. You can then reconfigure as necessary or see if it's assigning the same IP to multiple systems.

Other idea: statically set your IP to something in the range and see if you can get connectivity.

If you mention your OS I can be more specific on how to do these things (XP / Vista / 7).

The address you have is a zero-config address. This is usable only for the local network. You end up with this because you are not getting a DHCP address from your router. Possible solutions.

  1. Check that you have DHCP enabled on your router. If you have multiple computers connected to the router make sure your range is larger than the number of computers connecting.
  2. Your network cable may not be working well. Disconnect and reconnect it. Try replacing it if you have a spare. For wireless, you may not have the right security key.
  3. You can manually add an address by opening the configuration for the card from the Network setting menu. Use and address like 192.168.0.9.
  4. In the routers menu you may be able to manually add routing entries. If so, try adding 169.245.0.0/16. If it uses a netmask, the mask is 255.255.0.0. Set the router address to something like 169.254.0.1 if you need an address.

You likely need to configure your router. There are a few options/steps, in order of severity (more detailed information can be specified if you provide the model of your router):

  1. Try opening the TCP/IP Properties dialog and setting the IP manually to 192.168.0.3 to see if you can get network access at all

  2. Open a browser and navigate to your router’s address (normally http://192.168.0.1) and find the DHCP section of the configuration panel. You can probably configure it to be a dynamic or static server with several more options (check the MAC address and copy/clone it from your system if your NIC has changed)

  3. If you do not have specific, custom settings for your router, try pressing the Reset button briefly to do a simple reset, but if it still doesn’t work, try holding the Reset button for 10-20 seconds to do a full reset-to-default

I think 192.168.0.1 would be the router/gateway in this case. –  iglvzx Feb 1 '12 at 6:28

@iglvzx, normally yes, but they said 192.168.0.2 We’ll have to wait for a clarification. –  Synetech Feb 1 '12 at 6:38
