NETGEAR's Cable/DSL 54 Mbps Wireless Router lets you experience the blazing-fast network wireless speeds of 54 Mbps up to five times faster than the popular 802.11b wireless network. These higher speeds make it a snap to web surf, download large files, videoconference, stream high-quality digital movies, MP3 music and photos and play online games.

Auto-sensing chooses the fastest connections possible on your 10/100 Mbps wide area network and four local area network ports. True Firewall (SPI) advanced security provides maximum protection from professional hackers. URL blocking and e-mail alerts provide parents with controls to limit access to inappropriate web sites and monitor children's access. Simple to install, you just follow the cues shown on your PC screen and your router will be up and running in no time. Smart Wizard auto-detects and configures for the best ISP connection, while UPnP (Universal Plug and Play) makes it easy to use your computers, gaming consoles and other client devices - wireless and Ethernet - for gaming, instant messaging, and other applications.
