D-Link Viper 2600 DSL-3900 Review

In the past, we used to connect to the internet via some noisy gadget that usually goes through the known dial-up noise. Thankfully, we now have access to better forms of technology today, and these include VDSL, ADSL, HFC, and Fibre which can easily connect to the internet in a snap. Unfortunately, this means that there is a plethora of options available which makes choosing the best device really tricky. Thankfully, companies like D-Link are present to provide us with top-quality and excellent devices that allow us to connect to the internet seamlessly and with ease.

D-Link is one of the most trusted brands today when we talk about quality connectivity. They have been offering us excellent and extremely notable solutions that cater to all their clients’ needs and requisites. They’ve been offering great products since the year 1986, and they’re also well-known for their top-notch customer service assistance.

Just recently, D-Link announced and talked about one of their latest routers aimed for consumers. This is the D-Link Viper 2600 DSL-3900 MU-MIMO Gigabit router. This high-power Wi-Fi router is designed for ultimate performance while combining extremely fast, next generation 2,600 Wi-Fi with dual core processor and Gigabit Ethernet for improved HD gaming and streaming experience.

Today, we’re going to take a look at this new addition from D-Link. Let’s see if it’s just as good as other products from D-Link, if its specifications and features are highly notable, and if its performance is up to your needs and requisites.

D-Link Viper 2600 DSL-3900 Review- What’s in the Box?

The Viper 2600 DSL-3900 from D-Link comes in a nice sturdy and solid package. They made use of a black and red theme which is pretty appealing despite it being quite simple. On the front part of the box, you’ll see an image of the device right in the middle of the area; while on the upper left hand is the company’s name written in bold white. When you look at the upper right portion, there’s a sign that states “ultimate, streaming and gaming”.

Under the image, you’ll get to see the model name; at the lowest portion of the area, you will see a collection of symbols that represent the different features of the router. The sides and the back part of the box displays a more thorough description of the router’s features. On the side, you will also find an image of the router where its different parts are being described. Here, you will also see the other accessories that are included inside this package.

Aside from the router itself, other items that are included in the box would be the installation guide, warranty information, configuration card, Ethernet cable, a wall socket modem splitter, an RJ11 cable, and a power plug.

We’re quite happy that D-Link included all the necessary items in the package. Plus, these were packed nicely and neatly, so you won’t have to worry about any of these, nor the router itself, from getting damaged while in transit.

The Product

D-Link Viper 2600 DSL-3900 Review

The D-Link Viper 2600 DSL-3900 MU-MIMO Gigabit router isn’t your usual bulky device. However, it does have its own distinct appearance, specifically the four antennas that are displayed on the device.

We really like that the Viper 2600 DSL-3900 comes with a matte black finish which gives it a more quality and premium look to it. This is compared to the other similar devices that come with a glossy look to them. We also loved how the Viper 2600 DSL-3900 was designed. It did not appear in the usual box-like form which is a common design for routers today.

We also find it convenient that D-Link decided to put all the status display symbols right on the device itself, making it easier to see the status of the Viper 2600 DSL-3900 without having to shift and look underneath it. The device also comes with a total of four Gigabit Ethernet LAN ports, specifically the fixed connections, a single USB 3.0 port which is for shared media, then a VPN pass through to help you build your own VPN or virtual private network.

The Viper 2600 DSL-3900 from D-Link is definitely a quality device that gives you superior dual band 5GHz connection via the four available antennas on the unit. These are necessary to give you ultra fast and seamless performance, as well as a connection that is perfect for a variety of tasks whether these are normal or heavy loads. It is surely a router that is excellent for gaming, surfing, and streaming.

The Viper 2600 DSL-3900 from D-Link supports today’s latest standards like the concurrent dual band 802.11AC Wave 2, making it fit for 4K streaming and online gaming, as well as for surfing the internet.

Adding to these specifications is the easy Wi-Fi protected setup or WPS. It lets you easily add more devices to your network with just a press of a button. And just like other devices from the company, the Viper 2600 DSL-3900 comes with their WPA / WPA2 encryption to guarantee that your data is safe. Based on D-Link, the Viper 2600 DSL-3900 MU-MIMO Gigabit router backs theoretical speed that reaches up to 5GHz and 2.4GHz.

You will be able to reach comparable speeds on your personal network, yet given the rather inadequate NBN connections in different areas, you’ll most probably reach around 100Mbps when you get connected to the internet.

The Viper 2600 DSL-3900 has a signal rate of 2.4GHz 800Mbps / 5GHz 1732 Mbps while its wireless encryption includes WPA, WPA 2, and WPS.
