WRT-405 features the latest innovation wireless technology making the wireless networking world happened. Based on TI's Packet Binary Convolutional Coding (PBCC) technology (which is the candidate for the IEEE 802.11g standard), WRT-405 automatically adjusts to the fastest rate possible. It is also backward compatible and interoperable with IEEE 802.11b compliant wireless devices. Except for 64/128bit WEP encryption, WEP-256 and MAC address filtering is also provided to increase WLAN security and privacy. WRT-405 has a built-in AP on the LAN side. Other wireless clients can share the same broadband Internet connection and access other Ethernet devices on the LAN through the router's built-in 4-port switch. Virtual server, DMZ and natural firewall functions provide additional security and flexibility for both wireless and wired LAN users.
