The LevelOne WBR-3407A is used as a Router & Modem for connecting to ISP Internet services all around the world. As a modem, it withholds a built-in firewall, which defends you're computer from all the attacking hackers out there, in cyperspace.
As a router, it has 4 LAN Input/Output plugs, for different appliances (Video games such as the Xbox for multiplaying, Networking computers, Laptops and other various products), it works on both 802.11g & 802.11b (11/54Mbps). The router has an antenna for Wi-Fi purposes, which means that appliances are able to connect to it directly through the house wherever they're places (Wi-Fi printers, Laptops, Wi-Fi Toys, etc...)
Overall the router/modem is optimal for use throughout the house, houses and offices with more than 3 computer or appliances, which need all the space given, and the wireless option is allied with that need.
My only complaint for this router would have to be that if Wi-Fi is used over 10 meters, the speed tends to cut off highly.
