Hi, it does come with a network cable, and the power supply. I do not have the card that came with it, but it does have the username and password printed on the bottom of the router.
It has the ability to connect to 4 devices thru the Ethernet connection, or several wireless devices as well. I have used it to connect to a PS3 and a Wii .
Okay may want to make sure you not what all comes with your items and the model/part # of the item. Give as much detail. The better the details the better the listing. Just a little help.
