The VIPER 2600 (DSL-3900) Dual-Band MU-MIMO Gigabit VDSL2/ADSL2+ Modem Router is a versatile, high-performance router for the home and small office. With integrated VDSL, supporting download speeds of up to 100 Mbps, VPN passthrough, Quality of Service (QoS), AC2600 Wi-Fi, and four Gigabit Ethernet switch ports, the VIPER 2600 provides all the functionality that a home or small office needs to establish a high-speed connection to the Internet.

Fast and Reliable Home Network

The D-Link VIPER 2600 creates a blazing fast home network that connects all of your devices to your broadband Internet connection. Concurrent dual-band 802.11ac Wave 2 brings you the future of high-bandwidth wireless connectivity, allowing you to stream HD videos, make Internet voice calls, and surf the Internet from every corner of your home without interruption. Gigabit Ethernet ports provide high-speed wired connections for up to four PCs or other devices. Additionally, the Ethernet WAN port gives you the freedom to access the Internet via NBN or UFB Fibre, Cable, or other connection types.

802.11ac Wave 2 for Improved Performance

The VIPER 2600 features the updated 802.11ac Wave 2 specification, which improves on the bandwidth, range, and speed of 802.11ac Wave 1. The new and improved specification increases maximum speeds for the 5GHz band and adds more channels for higher speeds and less RF interference. This means you can surf the web or make Internet phone calls on the 2.4GHz band while streaming digital media on the 5GHz band from another room with minimal lag and stutter. Moreover, multiple-input and multiple-output (MU-MIMO) technology allows the VIPER 2600 to act as a dedicated router for each wireless client, giving them the ability to stream media simultaneously with faster response times. All this adds up to a better networking experience throughout your home or small office.

File Sharing Right at Your Fingertips

The VIPER 2600 lets you connect a USB storage device and instantly share documents, movies, pictures, and music. You can put your music library on a USB drive and share it with your entire home. You can show photos on the living room TV while a family member watches a movie on their computer. You can stream media files to multiple devices without interruption, or save them to your device for offline playback. The intuitive interface lets anyone immediately access a variety of entertainment options when you connect your own storage device.

Setting up the VIPER 2600 is easy with the D-Link easy setup wizard. Simply open the setup utility and follow a few easy steps to get your home network up and running.
