We could setup the Netgear wireless range extender in different ways. But, while using the web browser setup, we have to connect any Wi-Fi enabled devices with Netgear_EXT and visit www.mywifiext.net on any web browser. After that, we would be able to see the “New Extender setup” button. But sometimes, when we try to reach the www.mywifiext.net, we are not able to see the “New Extender Setup” button. We often see a error message on our web browser.
