Nope. No ethernet connection
What type of modem is it? It is like a home modem, or a cellular modem like a 3G modem.
IF it is just a normal home modem, I would see if you ISP will give you a better one with an eathernet port. A USB only modem is terrible for connecting up multiple devices.
IF it is a cellular or 3G modem, I would look at a wireless router that will support it. Such as something like thishttp://www.newegg.com/Product/Product.aspx?Item=N82E16833704072
Make sure you look at the compatibility list, for the router to make sure that it will support it.
Another option is to get a computer, plug the modem in to it, then share the connection to the computer's Ethernet card, then connect a wireless router in to that, via the router's WAN Port. Then you can connect wireless devices to the router.
I do this when I am stuck in a hotel with no internet, just get a little netbook and set it up. Does it great job but I wouldn't recommend this for long term solution.
