The Smart Connect feature of an ASUS router allows a user to automatically switch to an appropriate Wi-fi band. It steers to the best band for an optimal speed and delivers a robust Wi-fi speed to all the devices connected to your router?s network. If a user enables the Smart Connect in his ASUS router, the router.asus.com interface automatically adjusts the other network functions like bandwidth control, wireless mode, channel bandwidth, and extension channel. The interface brings variation in all other network features depending on the condition of your network.
