What This Product Does

Share the freedom of 3G! The TL-MR3420 3G/ 3.75G Wireless N Router allows users to share a 3G/ 3.75G mobile broadband connection with family and friends on the train, while camping, at the hotel - nearly anywhere with 3G coverage. Furthermore, by connecting a UMTS/HSPA/EVDO USB modem to the router, a Wi-Fi hotspot is instantly established.


High Compatibility-Tested in Field

Compatibility is the most important aspect to consider when you're selecting a 3G router. To safeguard maximum compatibility between our routers and the modem you would use with the router, TP-LINK has ensured our 3G routers are compatible with the ISPs in the regions in which they are sold. We have teams around the globe continually testing our routers with emerging modems to ensure flawless operation in all regions.


Comprehensive 3G/ WAN Back-up Strategy

The TL-MR3420 features a 3G/ WAN connection back-up, which keeps users online when one connection fails. TP-LINK's 3G Router provides users with both ‘3G preferred†and ‘WAN preferred†back-up modes, compared to other brands who provide only one or the other. This affords users a high degree of flexibility when configuring their networks.


Wireless N Speed & Range

Complying with the IEEE 802.11n standard, the TL-MR3420 can establish a wireless network with transmission speeds of up to 300Mbps, while mitigating data loss over long distances and through obstacles in a small office or a large apartment. It even maintains its effectiveness in steel or concrete buildings.


Above all, users are able to easily receive their wireless network's signal at longer distances from the router, as opposed to Legacy 11g products that require the user to be much closer.


WPA / WPA2 Encryptions - Advanced Security

WEP encryption is no longer resilient enough to safeguard a userâ€s Wi-Fi network. The TL-MR3420 provides both WPA and WPA2 encryptions (personal and enterprise), that protects your wireless N link from any malicious intruders.
