3COM ® WIRELESS 11G CABLE/DSL ROUTER

EXTENDED RANGE TECHNOLOGY

The 3Com Wireless 11g Cable/DSL Router comes with an advanced chipset with a new baseband architecture that enables long-range connections. This eXtended Range (XR) technology can provide single access point coverage in home networking environments, helps eliminate the dead spots in corporate wireless LANs, and provides outdoor coverage of up to two times the distance of competing WLAN solutions.

MULTIPLE SECURITY FEATURES

Advanced wireless security and multiple firewall features offer higher levels of protection for the network. To help shield wireless connections, this router provides 128-bit WPA/WPA2 with TKIP/AES encryption for maximum security, and 40-/64- and 128-bit WEP encryption for legacy clients.

URL filtering, a Stateful Packet Inspection (SPI) firewall with hacker pattern detection, traffic metering and other security features help protect the entire network from attacks and other Internet security risks.

ROBUST ROUTING FEATURES

IP (RIP 1 and 2) and static routing allow this router to be used in multi-network environments. Domain Name Service (DNS) enables users connecting to the Internet with dynamic IP addresses to use network applications such as Web or FTP servers that normally require static IP addresses.

RELIABLE AND SIMPLE TO USE

Designed to meet 3Com’s proven standards of quality, reliability is assured and supported by a three-year hardware warranty. A browserbased user interface and simple setup wizards ease installation, configuration and administration.
