TP-Link TL-MR3420 3G/3.75G Wireless N Router

The TP-Link TL-MR3420 3G/3.75G Wireless N Router provides a quick, easy way to setup a 300Mbps wireless network and share a 3G/3.75G mobile connection with other computers at your location. Just connect a UMTS/HSPA/EVDO USB mobile broadband card to the router for an immediate hotspot allowing the users to access the internet anywhere there is coverage.

And you'll never have to worry about service interruptions, since the TL-MR3420 has true 3G/WAN connection backup. Set 3G/3.75G or WAN (xDSL/Cable) as your primary link. If your service goes down the router will automatically switch to the secondary link and remain there until service is restored. Then it will switch itself back to the primary link.
