You can use a computer or mobile device connected to the network of the extender to find the Netgear wifi extender IP address. Go to the address bar in a web browser once it is open. You will be prompted to enter your login information. The IP address should be listed on the "Settings" or "Status" page once you've logged in. As an alternative, you can also find the extender's IP address by using a network scanning programme. You can go to our website for additional details.
