IP addresses naturally expire over time, and under most circumstances, your computer will lease a new IP address for you. If your computer is unable to connect to the internet, you may need to manually release your IP address, then renew your lease to retrieve a new one.

You should release and renew your IP address if you're still unable to connect to the internet after completing these three steps:

- Test a different device on the same network to see if other devices are also exhibiting the same symptoms
- Contact your ISP for potential outages in your area
