The NETGEAR N300 Wireless ADSL2+ Modem Router Mobile Broadband Edition is a full featured Wireless-N router with Integrated ADSL2+ Modem and a failover or backup option to connect to a 3G+ Mobile Broadband network in case of DSL outage. Internet traffic will be temporarily routed via the secondary Mobile Broadband Internet access. When normal service is restored to your primary ADSL line, all traffic is switched back. The Mobile Broadband connection can also be used as a primary Internet connection in situations where no DSL/cable/satellite connection exists. When not using the backup option, the router can be used to share a USB storage device with any computer in the network.
