How to Refresh IP Address

Change public IP address

Find the device's current IP address. To know whether the final IP address was changed successfully, you need to know the device's current IP address.

Power off the device. This can be the computer, phone or tablet whose IP address you want to change.

Unplug the modem and router from the Internet and power source. This process is essentially a Wi-Fi reset.

If the modem and router are integrated 2 in 1, you just need to unplug all the wires of the device.

Wait 5 minutes. This is just enough time for your Internet service provider to allocate a new public IP address to you.

Plug the modem cable back in. The device will start to light up. All lights on the modem must be on or flashing before you continue.

Reconnect the router. After a few minutes, the light on the router will also begin to flash and then stay steady.

Power on the device. After restarting, your device will connect to the Internet, but you may need to select and connect to the network manually.

Open an Internet browser. We will use our regular Internet browser to view the IP address.

Enter "What is my IP address" into the browser. If the IP address displayed is different from the previous address, it means you have succeeded.

If the IP address does not change, you may need to power off the router for longer. Try leaving the router off overnight and turning it back on the next morning.
