n5105 soft router network issues

Ok I got the image flashed.. got the ui going.. but I can't get this thing to even recognize my modem.. I need to do somthi g with interfaces but for the love of gold I don't know how..

This is SO foreign to me.. please someone patient walk me through this.

What kind of modem you have?

Have you managed to get one of the ports reassigned back to WAN ?

Everything working flawlessly thank you for your assistance.. didn't mean to ghost just i had been at it and few hours.. lol

Just out of curiosity is there any real reason to upgrade chips or is the n5101 more then enough for routing..??

Again thank you.

Depends on your internet connection speed.
