Resolving 169.x.x.x IP address problems

This article outlines methods of resolving issues with a 169.x.x.x IP address. This address results from a built in feature of windows called automatic private IP address(APIPA). When your computer is unable to find a DHCP server the APIPA service will assign itself a 169.x.x.x IP address. According to Microsoft, the APIPA service checks for a DHCP server every five minutes.

Releasing the IP address
1. Click on Start and click Run.
2. Inside Run, type ipconfig /release to release the IP address.
3. Then after the IP address is released, type ipconfig /renew

Disabling the Ethernet Adapter
1. Click on Start and right click on My Computer. Then click on Manage.
2. Click on Device Manager and then Network Adapters
3. Under Network Adapters, right click on your Ethernet adapter and select Disable.
4. Wait approximately 5 seconds and right click on it and click Re-enable.
5. This restarts the DHCP client and tries to obtain an IP address from the Network.

Check the Ethernet cable
Sometimes a bad Ethernet cable can cause your system to receive a 169 IP address, try changing out the cable for a new one.
Disable antivirus and firewall applications
Disable/uninstall any external firewall, antivirus, or spyware programs (eg. Norton Internet Security, McAfee Security Center, Trend Micro 2007, Webroot).
Restarting the QoS packet scheduler Protocol
1. Click on Start and click Control Panel.
2. In Control Panel, double click on Network Connections and then Local Area Connection.
3. Click on Properties and uncheck QoS Packet Scheduler.
4. Click Ok and repeat the process.

Restarting the DHCP service
1. Click Start and select Run.
2. Type services.msc in Run and click Ok.
3. Find DHCP service and right click on it. Click on Stop.
4. Reboot the computer.
5. When the computer boots up, click Start and select Run
6. Inside Run, type the following: netsh int ip reset log.txt
7. Click Ok.

System Restore
1. Open Start and click on Programs and then Accessories.
2. Then click on System Tools.
3. Click on System Restore and select a restore point when you were not experiencing this problem.
4. Restore your system.

  • Go to the Start menu, go to Run, and type "CMD" in the dialog box (without the quotes.)

  • jQuery(document).ready(function(){ jQuery('#jsArticleStep2 span.image a:first').attr('href','http://i.ehow.com/images/a01/vq/ee/computer-ip-address-windows-1.2-800X800.jpg'); });

    Now you should see a dark (DOS) window that looks just like the picture on the left of this article step.

    Without the quotes, type "IPCONFIG" and press ENTER.

    Now you should see some network information, along with the IP ADDRESS of your computer listed.

    wireless router is connecting to a 169 ip address instead of a 192 ip address. I know it's an issue regarding the DHCP server but it's not making any since, since I've done ipconfig /release, renew and it just adds more injury.


    When your computer is trying to request IP address from a DHCP server but it does not see the DHCP server it will give up and make up an IP address for itself. This IP will often look something like 169.x.x.x. This is a fake local address that Windows assigned to your PC when it couldn't reach a DHCP server.

    Make sure that your computer is connected to a network with working DHCP server.

    I cannot print to my HP 2700 all-in-one printer. IP address 192.168.2.3 Can ''ping'' but not print . Also I am getting ''no connectivity'' messages which come and go sometimes staying for several minutes other times a few seconds . The router is an edimax AR-7265WnA


    You could try the steps outlined in this article, but if it's a connectivity issue from the router's side, that won't resolve it. (If you're on a Mac, see here.)
    There was a firmware release for your router in June, that you should download and apply if you haven't already. available here. &see instructions here.
    To troubleshoot the wireless connection, this site and particularly this article may help. Also see these suggestions.

    I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.
