I try to configure a Netgear EX6200, as described on label and other instructions, including:
I connect to the wifi that the device provides.
I then access "http://www.mywifiext.net".
In Chrome, Chromium, Firefox or Edge quietly force a redirect to "https://www.mywifiext.net". (This is because www.mywifiext.net is included in "HSTS preload" list as indicated here: https://hstspreload.org/?domain=www.mywifiext.net )
The device does not support https, so the browser will fail to connect, and show any kind of "cannot connect to the server" message.
(The device is running the latest firmware, V1.0.3.94_1.1.128)
