*Deal Alert! Netgear 5 port switch, $12 (68% off)

Out of ports on your router?  Want to hook up 2 devices but only have 1 wall port?  Your router already has the ability to connect more computers with their own ip addresses, you just need a switch to make those connections.  If your modem is also a router then this is all you need to hook up multiple devices.
