Cannot Access Asus RT-AC68U via http (port 80)

If you try to go to http://router.asus.com and you get the following message:

Settings have been updated. Web page will now refresh. Changes have been made to the IP address or port number. You will now be disconnected from RT-AC68U. To access the settings of RT-AC68U, reconnect to the wireless network and use the updated IP address and port number.

It likely means insecure http on port 80 is disabled.

You need to access it via https, likely on port 8443, like so: https://router.asus.com:8443

If that doesn’t work, make sure you add the following to your /etc/hosts file:

192.168.1.1	router.asus.com

If using Windows, then the file lives C:\Windows\System32\drivers\etc\hosts.
