After connecting into the router, 3G/4G USB Modem will be regarded as the WAN3/WAN4
port. However, the original WAN1 and WAN2 still can be used and Load-Balance can be done
in the router. Besides, 3G/4G USB Modem in WAN3/WAN4 also can be used as backup
device. Therefore, when WAN1 and WAN2 are not available, the router will use 3.5G for
supporting automatically. The supported 3G/4G USB Modem will be listed on DrayTek web
site. Please visit www.draytek.com for more detailed information.
