The DI-764 multimode wireless router is also a best of both worlds solution for those operating wireless networks in public areas where the extra bandwidth can attract additional paying customers. This is especially applicable to wireless networks in busy commercial enterprises like coffee shops, bookstores, high school or university libraries, or anywhere people gather with their computers.
In addition to simultaneously bridging 802.11a and 802.11b wireless networks, the D-Link AirPro DI-764 can bridge to wired networks with its four integrated 10/100 Fast Ethernet ports. Advanced users will be pleased to find easy to apply, policy-based content filters that can be set based on MAC address, IP address, URL and/or Domain Name and scheduled to be in effect at certain hours of the day. Additional features include pass-through of multiple concurrent IPSec and PPTP VPN sessions for telecommuters or for anyone who needs to transmit sensitive information more securely. All of these features are accessable in an easy-to-navigate, web-based user interface.
With a few quick clicks, the DI-764 makes it easy to quickly and securely connect computers to share a high-speed Internet connection, files, resources, games or just to communicate.
