Wireless-G VPN Broadband Router Chapter 1: Introduction Welcome Thank you for choosing the Linksys Wireless-G VPN Broadband Router. The Wireless-G VPN Broadband Router will allow you to network wirelessly better than ever, sharing Internet access, files and fun, easily and securely. How does the Wireless-G VPN Broadband Router do all of this? A router is a device that allows access to an Internet connection over a network. With the Wireless-G VPN Broadband Router, this access can be shared over the four switched ports or via the wireless network, broadcast at either 11Mbps for Wireless-B or 54Mbps for Wireless-G. To protect your data and privacy, the Wireless-G VPN Broadband Router can encrypt all wireless transmissions with up to 128-bit WEP encryption and supports the WPA standard, which provides greater security opportunities. The Router also has a powerful Stateful Packet Inspection (SPI) firewall and Network Address Translation (NAT) technology to protect your PCs against intruders and most known Internet attacks. Its Virtual Private Network (VPN) function creates encrypted "tunnels" through the Internet so up to 50 remote or traveling users can securely connect to your office network from off-site, or users in your branch office can connect to a corporate network. All of these security features, as well as full configurability, are accessed through the easy-to-use browser-based utility. But what does all of this mean? Networks are useful tools for sharing computer resources. You can access one printer from different computers and access data located on another computer's hard drive. Networks are even used for playing multiplayer video games. So, networks are not only useful in homes and offices, they can also be fun. PCs on a wired network create a LAN, or Local Area Network. They are connected with Ethernet cables, which is why the network is called "wired". PCs equipped with wireless cards or adapters can communicate without cumbersome cables. By sharing the same wireless settings, within their transmission radius, they form a wireless network. The Wireless-G VPN Broadband Router bridges wireless networks of both 802.11b and 802.11g standards and wired networks, allowing them to communicate with each other. With your networks all connected, wired, wireless, and the Internet, you can now share files and Internet access-and even play games. All the while, the Wireless-G VPN Broadband Router protects your networks from unauthorized and unwelcome users.
