Do you have wireless router in your house? If so, you can buy another one or an access point and have no wires going acorss your livingroom. Or use the powerline

there is some more infor needed to answer networking question : how do you get internet to desktop ? what do you plug your desktop into ? brand model #
@ The Only Paisa Left If you only have a modem and it's connected to your desktop, you'll want to buy a router as well. If configured properly will also make your desktop system more secure on the WAN.
For wireless going to the kbox, you can buy a router and turn it into a client or power adapter. Or run cable from the router to the box
