There are already much 3G USB modem information embedded in the router. The USB modem

parameters will be set automatically if the card is supported by the router. But when the router

finds the card you just insert "unknown" to it, it will prompt you to set these parameters. The router

can identify your "unknown" card if the correct parameters are in the list. We suggest you to do the

“3G USB Modem Setting” only in such circumstance.
