The Dual-Band Wireless A+G Broadband Router is like four devices in one box! The Router function lets you securely share one high-speed Internet connection among your entire network, while the 4-port full duplex 10/100 Switch jump-starts your wired-Ethernet network. Connect four PCs directly, or daisy-chain out to more hubs and switches to create as big a network as you need.The Dual-Band Wireless A+G Broadband Router also contains two Wireless Access Points, supporting all three wireless networking specifications. The first Access Point uses the 2.4 GHz radio band, supporting both the popular and inexpensive Wireless-B (802.11b) standard at 11 Mbps, and the new, almost five times faster, Wireless-G (draft 802.11g) at 54 Mbps. The second Access Point radio operates in the 5 GHz band, and supports Wireless-A (802.11a) networking, also at 54 Mbps. Since the two radios operate in different bands, they can work simultaneously, blanketing your wireless zone with bandwidth.To protect your data and privacy, the Dual-Band Wireless A+G Broadband Router can encrypt all wireless transmissions. The MAC Address filter lets you decide exactly who has access to your wireless network. The Router also serves as a DHCP Server, has NAT technology to protect against Internet intruders, DMZ capability, supports VPN pass-through, and can be configured to filter internal users' access to the Internet. Configuration is a snap with the web browser-based configuration utility.With the Linksys Dual-Band Wireless A+G Broadband Router at the center of your home or office network, you can share a high-speed Internet connection, files, printers, and multi-player games with the flexibility, speed, and security you need!
