N300 Wireless ADSL2+ Modem Router DGN2200M Mobile Edition
ADSL with Failover to Mobile Broadband
Note: Incorrectly connecting a filter to your wireless modem router will
block your ADSL connection.
Note: Because the USB port on the wireless modem router is used for
connecting the broadband mobile modem cable, you are not able to
use the USB port for both a ReadyShare storage and a broadband
mobile Internet connection at the same time even when using a USB
hub to fan out the USB port.
