3G On-the-Go
TP-LINK's TL-MR3420 3G/3.75G Wireless N Router allows you to quickly set up a 300Mbps wireless network on-the go and share a 3G/3.75G mobile connection. By connecting a UMTS/HSPA/EVDO USB adapter to the router, a Wi-Fi hotspot is instantly established allowing users to share an Internet connection anywhere 3G/3.75G coverage is available. So wherever you are you'll have a reliable wireless connection to accommodate your networking needs.
Always Connected
Nothing is more frustrating than losing your Internet connection in the middle of your work. To avoid such interruptions and provide our customers with an always-online connection, TP-LINK introduces the TL-MR3420, a robust 3G/3.75G wireless N router with true 3G/WAN fallover capability.
You can set the primary link as 3G/3.75G or WAN (xDSL/Cable). TL-MR3420 switches to the secondary link when your primary service is interrupted. Once the service is restored, the router will automatically fallback to the primary link–keeping your business online with the minimal interruption to users.
  • Compatible with UMTS/HSPA/EVDO USB modems, tested in the field
  • 3G/WAN fallover guarantees an 'always-online' Internet connection
  • Wireless N speeds up to 300Mbps
  • Supports PPPoE, Dynamic IP, Static IP, PPTP, L2TP Cable Internet access
  • SST technology dramatically increases link robustness and stability
  • CCA technology enhances your signal stablility by automatically avoiding channel conflicts
  • Wireless security encryption is easy to setup, just push the QSS button
  • WDS wireless bridge provides seamless bridging to expand your wireless network
  • IP based bandwidth control allows administrators to determine how much bandwidth is allotted to each PC
