I want to change my wifi password to another custom encryption key, via the Gateway Settings page, but Firefox just alerted me that that page is not secure! I suspect a neighbor of hacking into my system. I live in a large apt. building with high transience, including AirBnB units. I really don't want anyone from the other side of the wall (or hallway, ceiling or floor) to watch me key in my new password. Thanks for anyone's help.
