Some of the modem we sell do not have wireless capability, and have only one network cable port. To have wireless capability you need to buy a modem from us (or any store as long as it is on our list of modems), which has wireless modem capabilities, or you need to own or buy a router which has wireless capabilities and plug it into the modem. Our lists of modems tell you which are wireless and which are not, and that info is also on the order forms on our website.
