The D-Link DI-784 is a four-port, tri-mode wireless router that offers data transfer rates up to 108Mbps. The DI-784 operates in both the 2.4GHz and 5GHz frequency spectrums supporting 802.11b and the newer, faster 802.11a and 802.11g wireless standards. The DI-784 can achieve wireless speeds up to 108Mbps in a pure 802.11g or 802.11a environment through the use of new wireless technology such as Packet Bursting, FastFrame, Compression & Encryption, and Turbo mode provides enough bandwidth large enough to handle video/audio streaming applications. The DI-784 also features strong security and includes an integrated 4-port switch for additional Internet or resource sharing at wire speeds. Less

The Cisco 1800 Series fixed-configuration routers help enable a network infrastructure for SMBs and enterprise small branch offices, providing access to the Internet, corporate headquarters, or other remote offices, while securing and protecting critical data with integrated Cisco IOS Software security features and capabilities. They also help businesses reduce costs by enabling deployment of a single device to provide multiple services (integrated router with redundant link, LAN switch, firewall, VPN, IPS, wireless technology, and quality of service [QoS]) typically performed by separate devices. Cisco IOS Software allows this flexibility, providing the industry's most robust, scalable, and feature-rich internetworking support, using the accepted standard networking software for the Internet and private WANs.

Versatile, powerful, and dependable router from Cisco.

Fairly expensive.
