Unable to release and renew my IP address. How to troubleshoot?
At times your computer may not be able to renew its IP address. This happens due to various reasons. Let's look at some of the common causes of this problem and how to fix it.
- You moved your computer or laptop from one network to another. This causes your computer to try and contact the earlier server that assigned it the old IP address and in the process it can not renew the IP.
- The DHCP server is unavailable or not reachable. The DHCP server that assigned the IP address must extend the lease duration of your IP address and in case it's not available, the computer can not renew its IP address.
- Your wireless router is not reachable or is down. In case you use a wireless router, make sure that the signal strength is good, otherwise you might have trouble in getting your IP renewed.
- Your network cable might not be plugged in. It's rare to happen but it does happen. Network cable when not plugged in properly can prevent your computer from contacting the DHCP server to renew the IP address and connect to the network as well.
If you are sure that your computer is physically connected to the network, you may want to try the following simple steps to release and renew the IP address. In other words, release the IP to get a new one assigned. These steps are applicable to Windows XP, Vista, Windows 2000 and Windows 7 operating systems.
- Click the Start menu button on the Windows taskbar and click Run on this menu.
- On the run prompt, type CMD and hit enter. A command prompt window will appear on the screen.
- In the command prompt window, type 'ipconfig/release' (without the quotes) and hit enter.
- Type 'ipconfig/renew' (without the quotes) and hit enter to either renew or get a new IP address
Your computer should now be assigned with a new IP address.
