A well-positioned antenna can reduce interference and signal weakening. This leads to a more reliable connection. Many IoT devices, smart home devices, and older Wi-Fi devices mainly use the 2.4 GHz band. This is a Wi-Fi 4 router, with slower data transfer speeds. This can result in slower downloads, video buffering, and reduced performance. Real-world RT-N15U router speeds are lower than its theoretical maximum speed.

WEP was the first Wi-Fi security protocol. But it is now seen as weak and easy to hack. The introduction of WPA2 (Wi-Fi Protected Access 2) improved upon WEP. It provides stronger security. WPS (Wi-Fi Protected Setup) provides an easy method. It connects devices to a Wi-Fi network.

The USB 2 port has a maximum theoretical data transfer rate of 480 megabits per second (Mbps). By connecting a USB printer to the RT-N15U router, you can make it accessible to all devices on your network. This router has a USB file server. It lets you connect external storage devices to your network. For example, you can connect USB flash drives or hard drives.
