Apart from the wifi.wavlink.com setup web address, you can use the extender’s IP address to get the setup page. It might happen that the login and setup windows will be not accessible to you if you are using the web address imperfectly. But, after inserting that address perfectly, if you are unable to visit the setup window, there can be a technical error in the extender. In that case, you can try to use the IP address instead of the web address of the extender. So, just type the default IP address in the browser’s search field and click enter. Doing so will bring you to the login window, which will prompt you to fill in the username and password. When you insert these credentials, the setup page will be visible on your device’s screen. Use the instructions shown on the screen for the further process.
