This RangeMax NEXT PCI adapter ensures that your desktop computer can connect from anywhere in your home, with maximum coverage and bandwidth, enabling you and the rest of your household to simultaneously connect to multiple Internet services, including online gaming, video streaming, and MP3 downloads. When used in conjunction with NETGEAR's WNR834B RangeMax NEXT wireless cable router, the WN311B PCI adapter will provide maximum coverage and bandwidth, enabling you and your entire household to simultaneously connect to multiple Internet services and online media. To explain the capabilities of RangeMax NEXT wireless router and adapters further: Imagine connecting to the Internet from anywhere in the house, without a cable. Then imagine everyone in the house connecting at the same time, and all doing things online or over the network - all at the same time: Watching a Hi-Definition video or TV program in the living room, browsing the Internet in the study, playing online games in the den, downloading MP3 music from the dining room - all at the same time. This is what RangeMax NEXT is capable of, all over a single home wireless network that provides a constant, 'rock-steady' connection. With the RangeMax NEXT PCI desktop PC adapter inserted, your computer will maintain a steady, constant connection (when used in conjunction with the WNR834B Wireless Router), with sufficient bandwidth available to stream, download, browse the Internet, and transfer files all at the same time. With RangeMax NEXT you should not experience any more frustrating interruptions or freezes, just a constant connection that enables you and your household to use the Internet and wireless network as you choose, whenever you choose. Touchless WiFi Security makes creating the highest level of network security easy and includes industry standard wireless encryption standards for you to choose from: WEP, WPA-PSK, or WPA2-PSK. These security features enable you to 'lock-down' your home wireless network, protecting you against unwanted intruders. As with all NETGEAR wireless products, the WN311B RangeMax NEXT wireless PCI adapter is easy to set-up with NETGEAR's Smart Wizard. This RangeMax NEXT adapter is backward compatible with existing wireless devices, including 54 Mbps 802.11g and 11 Mbps 802.11b - but bear in mind that the coverage and bandwidth won't be as good with these devices on your home wireless network.
