Many IoT devices, smart home devices, and older Wi-Fi devices mainly use the 2.4 GHz band. This router operates on both the 2.4 GHz and 5 GHz frequency bands. This is a Wi-Fi 4 router, with slower data transfer speeds. This can result in slower downloads, buffering, and reduced performance. The introduction of WPA2 (Wi-Fi Protected Access 2) improved upon WEP. It provides stronger security.
