Device purpose
Share your 3G / 4G connection freedom! The TL-MR3420 N-Series wireless router with 3G / 4G standards allows for sharing of mobile broadband 3G / 4G connectivity via WiFi or an Ethernet cable. By connecting a 3G / 4G USB modem to the router, you can create a Wi-Fi access point in minutes, through which wireless shared Internet access is possible, as well as information and applications on the local network.

Support any modems
Compatibility is the most important point to consider when buying a 3G / 4G router. TP-LINK has taken due measures to provide 100% compatibility of the router with modems that will be used with it. 3G / 4G TP-LINK routers successfully work with Internet service providers in those regions where they are sold. Worldwide, working groups have been created that constantly conduct testing in new regions with new modems, so users can be sure that their 3G / 4G router will work flawlessly in the region where they live and work.

Supports 3G / 4G and wired redundancy
A distinctive feature of the TL-MR3220 model is support for the 3G / 4G standard and a wire connection with a channel backup function, so the Internet connection always remains active. Users can specify the preferred connection mode in the settings, one option from two: 3G / 4G or WAN, the second option will be a backup connection. At the moment, this is the only device that offers the ability to use two types of connection at one time. This allows you to get a wider range of settings, reduce downtime and save funds to pay for an Internet service provider.

N standard data transfer rate and solid wireless coverage area
The TL-MR3220 router supports the IEEE 802.11n wireless standard and helps deploy a wireless network with data transfer rates of up to 150 Mbps with lower data loss when transmitting over long distances and over obstacles in a small office or large apartment, even in a reinforced concrete building. Moreover, users can easily catch the signal of their wireless network from a greater distance than was previously possible with devices that support the 802.11g standard.

WPA / WPA2 Encryption Modes - Enhanced Security
WEP encryption is no longer considered reliable enough to protect wireless networks. The TL-MR3220 router uses WPA / WPA2 (Personal / Enterprise) encryption modes developed by the WI-FI Alliance industry group, which deals with the compatibility and security of wireless devices for local area networks. WPA / WPA2 encryption ensures protection against any attacks and unauthorized access.

Share via 3G / 4G connectivity
The TL-MR3220 allows working at 4G standard speeds and supports more than 200 models of 3G modems, allowing users to share 3G / 4G broadband mobile connectivity via a wired or wireless connection.
