If you have a pc set to automatically obtain an IP and you recieve one of these addresses, windows has assigned this because it cannot find a DHCP server within the network subnet. Check to make sure your DHCP server is functioning correctly. If you do not have a DHCP server, you will need to manually set an IP configuration. + 0 Votes Home network router Macgyver.Hicks 7 years ago As this system is doing the same thing on a different network, Check the firewall first (could be set to block all). Next, I suggest uninstalling the NIC driver in the Device Manager. Afterward, shut down the computer and do a power reset by unplugging the power cord, then pressing and holding the power button for 30-45 seconds. This will allow the transistors to reset to their default positions. Plug the system in and turn it on. Windows should install a clean copy of the driver onto clean circuits. If this is does not get you a good IP address, try booting into Windows Safe Mode with Networking. Once in, check the IP. If it is still showing 169.254.*.*, there may be a problem with the NIC. Try a known good NIC. If it gives you a good IP from your network, there may be something starting in Windows Standard mode which blocks access to the network in general. + 0 Votes It assigns a APIPA address mohammed_k 5 years ago Hi Lloyd, since,Your system's NIC is set to obtain ip address automatically.It will get ip from dhcp server or it will assign itself as APIPA address (Automatic private iP Address) from range of (169.254.....) incase ,your dhcp server failes to assign the ipaddress to the client.
