D-Link Tri-Mode Wireless Internet Gateway
D-Link DI-774
Review & Specification:
D-Link, the industry pioneer in wireless networking, introduces another breakthrough in wireless connectivity - the D-Link Air Xpert DI-774 wireless router. This four-port, tri-mode, dualband router provides the most expanded user bandwidth available in a router. Hundreds of wireless clients can connect to this router using any one of its 11 non-overlapping channels to transfer data at speeds up to 5 times faster than previous wireless devices.
The DI-774 operates seamlessly and simultaneously in both the 2.4GHz and 5GHz frequency spectrums supporting the 802.11b and the newer, faster 802.11a and 802.11g wireless standards. For offices, schools or public hotspots that already use 802.11b devices, the DI-774 is a great way to expand an existing network and enable even more users to communicate with one another, access data and the Internet. Now, you can have a router that will compliment your existing network and protect the investment you made when you provided the convenience of wireless networking.
The DI-774 offers transfer rates up to 54Mbps in either the 2.4GHz or 5GHz bands. So, now large data packets travel from the router to a remote desktop or roaming laptop PC at up to five times the speed of previous wireless devices enabling everyone to work faster and more efficiently or watch a streaming video smoothly.
Network administrators can also partition the usage of the DI-774 by segmenting users on the wireless network by frequency band. Users who require special networking privileges - access to sensitive company data, videoconferencing, or connectivity to specific departments - may use just the 802.11a channels; while other employees may just use the 802.11b and 802.11g channels. This type of user segmentation optimizes the router s performance and delivers the best network experience to each set of users.
The DI-774 is ideal for those who require additional manage-ment, firewall, and other network security features - the 802.1x standard for wireless user authentication and WPA (Wi-Fi Protected Access) which dynamically encrypts data as it s being sent. And because the DI-774 allows the pass-through of multiple, concurrent IPSec and PPTP VPN sessions, IT managers can deploy DI-774s to their company s telecommuters and other remote employees who need to access sensitive information from a server or database or to communicate to a colleague confidentially. Filters on the router can also be set to restrict access to it based on the specific MAC addresses of wireless laptop or desktop cards on the network, or restrict the access of IP addresses, specific websites and/or web domain names. All of the router s settings are easily accessible in the operating system independent, Web-based software user interface that also features a step-by-step Setup Wizard to get the DI-774 up and running in just a matter of minutes.
The DI-774 also features an integrated 4-port switch allowing direct Ethernet connection to up to four computers for additional Internet or resource sharing at wire speeds.
