After connecting into the router, 3G/4G USB Modem will be regarded as the third WAN 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 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.
