WWW.MYWIFIEXT.NET is not a regular internet site but it’s a local web address which opens the new extender setup page or the Geniepage or the Netgear smart wizard of your Netgear wireless range extender, because of this you might face an error message
saying you are not connected to the Netgear wifi range extender.
