What should I do if I cannot access www.mywifiext.net?

First, make sure your computer or mobile device is connected to the extender network and the Device LED is solid green or amber. Try entering the extender's default IP address (192.168.1.250) in your web browser. If that doesn't work and your extender and router use the same WiFi network name, enter the extender's IP address directly (such as http://192.168.1.3). You can also try clearing your browser's cache, using a different browser, or assigning a static IP address to your computer.
