Looks like your Cisco is just a straight modem. Service providers now have a modem/router all in one type of unit to simply the home network experience for the average user. I have one of those to which I disabled the router part only because I have a couple of servers I run my network on. Anyway, your other alternative is to get a wireless N router such as this D-Link http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=6654485&csid=_61 or http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=2755284&CatId=2668 or something similar. Shop around of course as Tigers prices are not always the best. If you go the wireless route, make sure you get wireless N though for best video streaming results. Setup is not difficult and your TV should connect without issues. Good luck.
