While the router is booting up, a minimalist but useful failsafe recovery facility is provided to recover from bad firmware flash or reset to factory defaults. This is much more intuitive than the usual TFTP server recovery procedure and probably why the RT-AC66U needs the second flash ROM.
The default Network map view provides the user with a graphical overview of the status of the router and the devices connected to it.
Users can setup up to three wireless guest networks (SSIDs) and configure individual restriction for each band. That's a total of eight different wireless networks including the two private ones.
Traffic Monitor tab provides a real time traffic graph for each interface.
In the QOS tab, users can assign specific bandwidth limits and priority levels to certain applications.
Here at the AiCloud tab we can choose which features to be enabled for remote access at the Asus portal. Obviously you would need a broadband connection with a reasonable upload speed for a good user experience with these usages.
Like most other modern Internet Gateway appliances, the RT-AC66U allows USB hard drives, flash media, printers and 3G/4G modem dongles to be attached and shared on the network.
Similarly, there is basic firewall and URL filtering features.
The network services filter allows dynamic access control for devices on the network. The scheduling option allows additional flexibility.
