Product information

Description

Share Wi-Fi with your 3/4G dongle using the TL-MR3420, a 300 Mbps 3/4G router. Plug a compatible 3/4G USB modem into the router to create a Wi-Fi hotspot and provide internet access to multiple devices. The TL-MR3420 supports both wireless 3/4G dongles and wired WAN connections, offering flexible connectivity for home or small office use.

Advantages

The router converts a 3/4G USB dongle into a stable Wi-Fi network that can be shared with friends and family. It supports up to 300 Mbps wireless speeds and can handle up to 32 connected devices simultaneously. The TL-MR3420 also offers dual operation modes—wireless 3/4G and wired WAN—so you can switch between connection types as needed. Setup and management are simplified via an intuitive web interface and the Tether mobile app for Android and iOS.
