Introduction

If you're looking to upgrade your wireless network's capability to the newly released 802.11ac spec, there is certainly no shortage of products to help. In fact, like the days of wireless N, manufacturers are offering multiple devices, filling each performance niche in the market. While this is a good thing for users that want certain speeds and capabilities, it tends to clog up the market and lead to confusion of "what router do I buy?"

As we mentioned above, 802.11ac has introduced several markets for vendors to fill, and as such they have begun to do so with AC600, 750, 1000, 1200, 1300, 1750 and 1900 routers. At any rate you get the idea, the market has expanded rapidly and even more than ever before.

The D-Link DIR 868L is an AC1750 wireless router, as such it is also the top of the line when it comes to D-Link's portfolio. Capable of 1.3Gbps on the 5GHz band and 450Mbps on the 2.4GHz band, the 868L certainly offers, in marketing, top tier performance capabilities.

Though, we won't go into too much detail now as we're not quite sure if it has the increased range that makes the upgrade from 802.11n worthwhile.

Let's take a close look.

Pricing and Availability

As of this writing, the D-Link DIR-868L carries a MSRP of $189.99. However, I was able to find at several online retailers it priced at $169.99.

Availability is quite high at this time with Google shopping listing the router at 15 stores.

As wireless networking has proliferated in homes and offices around the world, and network vendors keep releasing new devices on a regular basis, you now have so many options that it's hard to make a choice. The truth of the matter is, regardless of how many features a wireless router or access point has, the two most important things about it are its speed and its range.

We test throughput and range in a dual-node network environment consisting of a Custom PC with a GIGABYTE Z77UP5 TH, Intel Core i5 3570K Processor operating at 3.3GHz with 16GB of DDR3 featuring the Startech.com ST1000SPEX42 quad port gigabit network adapter and a single HP ProLiant DL380 G5 Server with Windows Server 2012 R2 and a second Startech.com ST1000SPEX42.

D-Link DIR-868L Dual Band AC1750 Wireless Router Review 98 | TweakTown.com

Wireless throughput is tested using the ASUS PCE-AC68 PCI Express Network Adapter. Range is tested with a HP ProBook installed with an ASUS USB-AC56 adapter through USB 3.0.

We perform all tests in a real-world environment. You may get better range and throughput results in a spacious facility with few internal walls or outdoors. Our tests provide a benchmark for estimating the range and throughput of wireless networking devices in an indoor setting, with some obstacles.

D-Link DIR-868L Dual Band AC1750 Wireless Router Review 27 | TweakTown.com

The 868L managed to top our charts thanks to its impressive 1300 Mbps connection rate using the 80MHz width. Throughput of the unit topped at 450 Mbps.

Benchmarks - Wireless Range

Wireless Range

For wireless range, we need to refer back to the Network Infrastructure chart on page four of this review. Each chart herein is based on the locations on the table. To make it simple Location 1 is the closest and within Line of Sight, while Location 4 is the furthest away with many walls in between. Location 5 tests the routers ability to generate enough signal strength to penetrate to the second floor of a home.

D-Link DIR-868L Dual Band AC1750 Wireless Router Review 30 | TweakTown.com

Within our first range test, we find the D-Link offering increased range in location five over previous units.

D-Link DIR-868L Dual Band AC1750 Wireless Router Review 31 | TweakTown.com

Moving to the 40MHz channel width, 868L suffers slightly at location 4, but excels at all others.

D-Link DIR-868L Dual Band AC1750 Wireless Router Review 32 | TweakTown.com

Moving to the 5GHz band, we find a nearly identical pattern between the two tested routers.

D-Link DIR-868L Dual Band AC1750 Wireless Router Review 37 | TweakTown.com

The 5GHz 20MHz band allowed the 868L to connect at 176 Mbps at location one and two. Following this the router dropped off severely with locations three and four eventually returning to 176 Mbps at location 5.

D-Link DIR-868L Dual Band AC1750 Wireless Router Review 38 | TweakTown.com

5GHz 40MHz was able to connect at 400Mbps for the first two locations, a drop off ensued thereafter and again returned at location five.

D-Link DIR-868L Dual Band AC1750 Wireless Router Review 39 | TweakTown.com

Firing up the 5GHz 80MHz band the 868L connected at 867 Mbps, after which we find the drop off of the 5GHz band.

Power Consumption

Power consumption figures were taken from our Kill-A-Watt meter throughout testing.

The D-Link 868L peaks at 9 watts, after which the unit idled down to 7 watts.

Final Thoughts

[img]97[/img]

Having not previously touched a D-Link wireless router after the purchase of my 857 802.11n unit a few years back, I was quite surprised at the complete redesign of the "cloud routers". Though, it's not entirely a bad design, it does go away from the typical square form factor we are used to. Whatever the case, I do enjoy the new design as it welcomes the modern art movement into your living space as a functional device.

Performance of the router was a mixed bag. With the 2.4GHz band, we had a great connection with locations 1 through 3, but things took a turn for the worse when we moved outside that 20 foot bubble to location four. The 5GHz band again was exceptional even connecting at 1.3 Gbps in our initial testing, but moving outside the reach of 5GHz, connection rates fell down to a measly 20 - 30 Mbps. Even with that, the D-Link was hands down the best router for connecting to your network from above, on a second floor.

Management features have increased by a fair bit since I last touched a D-Link web UI. Here we have new "cloud" features like myDLINK and SharePort. With SharePort, you can access all your videos, music and photos on the go by connecting a USB storage solution to your router.

Market pricing of the D-Link 868L has the unit at $159.99. Comparable routers in this segment are the Linksys EA6700 at $179.99, the Netgear R6300 at $179.99 and the Buffalo AirStation Extreme 1750 at $139.99.

Growing up in a small farm town, tech wasn't around, unless it was in a tractor. At an early age, Tyler's parents brought home their first PC. Tyler was hooked and learned what it meant to format a HDD, spending many nights reinstalling Windows 95. Tyler's love and enthusiast nature always kept his PC nearby. Eager to get deeper into tech, he started reviewing.
