DI-784EOL EOS

Tri-Mode Dualband 802.11a/b/g (2.4/5GHz) 4-Port Wireless 108Mbps Router
Where to buy

Description

Dualband Operation
The DI-784 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-784 is a great way to expand an existing network that enables more users to communicate with one another, access data and the Internet. Now, you can have a router that compliments your existing network and protects the investment you made when you provide the convenience of wireless networking.

Fast Network Data Transfer
The DI-784 offers network data transfer rates of up to 108Mbps Turbo Mode in either the 2.4GHz or 5GHz bands. So, now large data packets can travel from the router to a remote desktop or roaming laptop PC at up to 15 times the throughput of previous 802.11b wireless devices, enabling everyone to work faster and more efficiently or watch a streaming video smoothly.

Network Segmentation
Network administrators can partition the usage of the DI-784 by segmenting users on the wireless network by frequency band. Users who require special networking privilege access to sensitive company data, video conferencing, 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.

Enhanced Security
The DI-784 is ideal for those who require additional management, firewall, and other network security features such as 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-784 allows the pass-through of multiple, concurrent IPSec and PPTP VPN sessions, IT managers can deploy the DI-784 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 be set to restrict access 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-784 up and running in just a matter of minutes.

Built-in 4-Port Switch
The DI-784 features an integrated 4-port switch allowing direct Ethernet connection to up to four computers for additional Internet or resource sharing at wire speeds.
