When you are connected to a network, your computer is usually assigned an IP address by your router for a limited time. Each of these so-called intellectual property leases has a maximum duration of 24 hours.

In most cases, the network router assigns the same IP address multiple times, but sometimes conflicts can occur. The IP address may have been assigned to another device by mistake, or your network adapter may have problems completing the IP lease renewal process due to misconfiguration or hardware issues.

First, open a Windows PowerShell window. To do this, right-click the Windows Start menu button on the taskbar and select Windows PowerShell (Admin). You can also do this from the old Windows command line.

  • If you see the command line in your menu, see the Previous article on how to switch menu items to PowerShell.
  • Type ipconfig / all to get a list of details of the current network configuration.
  • Type ipconfig / release to free your IP address. This will rid your network adapters of their assigned IP addresses.
  • After releasing the network adapters, type ipconfg / Renew to assign a new IP address lease.
