It took D-Link longer than they probably wanted to squeeze out its first AC1900 router, the DIR-880L. Perhaps it was angst over abandoning the upright cylinder format adopted for just about all its other AC class routers. Nevertheless, it’s out, it’s flat, so let’s take a look.

The DIR-880L does indeed look like most other AC1900 routers, with three designed-to-impress large dual-band dipole antennas arrayed across its rear panel, joined via RP-SMA connectors. The 880L’s data sheet says these are "high-gain" antennas, but omits actual gain numbers.

The callout diagram below shows the 880L has both USB 2.0 and USB 3.0 ports, just like NETGEAR’s R7000 Nighthawk, ASUS’ RT-AC68U and Linksys’ EA6900. All lights are on the top panel and most connectors are on the rear. Note none of the gigabit Ethernet ports have link or activity lights, so you need to log into the admin interface to see if stuff is actually connected.

The USB 3.0 port is awkwardly stuck on the left side and the WPS button, which bears no marking identifying it, sits in about the same position on the right side panel. At least D-Link didn’t hide the USB 3.0 port under a gawd-awful tethered rubber plug as ASUS did on the RT-AC87.

On a more positive note, there are mounting screw slots centered on the bottom side that allow you to decide whether ports and antennas point up or down when wall mounting.

You would think given its timing and pricing that the 880L would have a latest-and-greatest design. But you may be disappointed to learn that it uses the older Broadcom BCM4708A SoC as its main processor vs. the newer and more powerful BCM4709A. D-Link also cheaped out on memory, too, providing only 128 MB of RAM and 16 MB of flash.

At least they tried to do a decent job of heat-sinking, as evidenced by the big plate in the internal FCC photo below.

Removing the heatsink plate and RF can lids lays bare the 880L’s design, which alternates 2.4 and 5 GHz amplifiers to keep path distances to each antenna connector short. That’s the USB 3.0 port at the photo left front, wisely placed far away from the radios and shielded both top and bottom of the board, to eliminate causing problems with 2.4 GHz radio performance.

Table 1: Component summary


The 880L’s is the first router with the new, sparser admin interface I first encountered on the DAP-1520 AC750 range extender. As other reviewers have noted, the new look has both Yin and Yang. The good is that it’s more finger-friendly, making it easier to drive on touch-screen Win 8 notebooks or your favorite tablet. The bad is some features you might expect from a router of its class and price, such as DHCP reservation, parental controls, in-browser logs and access to transmit power control and other Wi-Fi knobs to twiddle, are not to be found.

The Home page adopts the current de rigueur network status look, complete with clickable icons that change the information displayed and provide links to associated function admin pages.

  • Storage web access


  • Quick VPN (L2TP over IPsec)


  • Triggered port forwarding
  • IPv6 port forwarding
  • Useful online help
  • Logs in browser
  • Parental controls (web filtering)
  • Traffic monitoring, limit alerts
  • iTunes server
  • UPnP media server index controls
  • UPnP disable
  • Remote access controls
  • HTTPS administration support

Most users will find the controls they want and even more among the features listed above. But if you’re looking to be able to monitor every CPU cycle or tweak buffer depths, you’ll want to take a pass on the 880L.

Some key features are hidden pretty well. For example, I was just about to wrap up the review and was taking screenshots when I stumbled across DHCP reservation and "Parental Control" features shown below, which I had missed up until then.

The "Parental Controls" feature is just scheduled general internet access, not content filtering, set by IP address, not MAC address. IP address is also used for DHCP reservation, although I’m sure MAC address is in there somewhere. But you won’t find it in the Client information displayed.

One key annoyance is there is no online help built into the router. The Help links shown in the GUI just dump you at the main D-Link support page. Online help would go a long way in helping users adjust to the new GUI.

D-Link said they are adding "adding additional VPN Setup details in the User Manual based on feedback received from the user community".

Features – more

The User Manual covers the basics. So when I went looking for information on how to set up Quick VPN I found only the cryptic information below, which seems to indicate that Quick VPN is helpful only for connecting via an iOS device. Querying the Support database for "Quick VPN" turned up nothing either. And, D-Link, you do know that Cisco also has a "QuickVPN"?

Remote admin depends mainly on the still-not-ready-for-prime-time mydlink portal. I’ve bitched about mydlink’s lameness enough, so won’t bore you here. But note that HTTPS admin is not supported and there are no remote admin controls.

There is no WPS admin screen. So if WPS goes awry, or you want to disable it, you’re out of luck. No advanced wireless features either. At least you get transmit power adjustment of High (default), Medium and Low, scheduled wireless on/off, radio disables and one guest network for both radios.

Updated 8/29/14

A big missing feature, however, is lack of a wireless bridge mode or support for WDS bridging/repeating. WDS bridging / repeating isn’t supported. But you can switch the router to act as a wireless bridge using the Device Mode switch on the Internet settings page. Unlike NETGEAR’s R7000, the 880L’s bridge mode has a network scan function making it much easier to connect the bridge to your main router.

Storage Performance

Windows filecopy tests were run using the standard NAS testbed connected to a router Gigabit LAN port and the standard USB drive formatted in FAT32 and NTFS [NAS test details]. Tests were run connected with the USB drive connected to both the USB 2.0 and USB 3.0 ports.

Table 3 summarizes USB 2.0 performance and includes some of the 880L’s AC1900 competitors. USB 2.0 doesn’t really test the limits of storage performance, so the 880L holds its own in this comparison.

For USB 3.0 results, Table 4 shows the results of using Broadcom’s older processor, with performance lagging behind the most comparable NETGEAR R7000 Nighthawk. It’s not really a fair fight with the ASUS RT-AC68U, which can’t work around its poor hardware implementation of its USB 3.0 port.

Routing Performance

Routing performance for the 880L using our standard test method is summarized in Table 5. At least here, the 880L does pretty well. Sure, its unidirectional up and downlink throughput tends to make you scroll down a bit to find it in the Router Charts. But you really can’t complain much about the throughput, which is more than enough for most internet connections.

Test Description DIR-880L
WAN – LAN Throughput – (Mbps) 766
LAN – WAN Throughput – (Mbps) 810
Total Simultaneous Throughput – (Mbps) 1354
Maximum Simultaneous Connections 37,689
Firmware Version 1.0.1
Table 5: Routing throughput

The IxChariot composite plot for the unidirectional tests shows steady throughput, with periodic spikes into the 900 Mbps range.

The simultaneous up and downlink plot below shows a preference for uplink traffic when both directions are running full blast. The jump up before 20 seconds is an IxChariot quirk. But the ramp up in WAN > LAN throughput after 30 seconds or so was reproduced in multiple runs. Still, the 880L should provide plenty of routing throughput.

Wireless Performance

The 880L is Wi-Fi Certified. It defaults to Auto channel on both bands and auto 20/40 MHz B/W mode on 2.4 GHz and Auto 20/40/80 MHz mode on 5 GHz upon power-up. The router comes with different 2.4 and 5 GHz SSIDs set, so you’ll be able to connect to your desired band without having to change router settings. The wizard that launches upon first login walks you through changing these settings as well as encryption.

The quick WPS pushbutton test with a Win 7 client ran without a problem, connecting with a WPA/AES secured connection. I skipped 40 MHz Coexistence and Fat channel intolerant tests and will probably stop mentioning this going forward.

Wireless throughput testing used our new Version 8 wireless test process with 1.0.1 version firmware loaded. The router was first reset to factory defaults, then Channel 6 and 20 MHz B/W mode was set for 2.4 GHz and Channel 153 and 80 MHz B/W mode was set for 5 GHz. The router was positioned in the test chamber with the antenna row centered on the turntable side-to-side (of chamber) and middle antenna centered on the turntable front-to-back. The 0° position had the front side of the router facing the chamber antennas.

The Benchmark Summary below shows the average of throughput measurements made in all test locations. The results rank the 880L in a tie with the ASUS RT-AC68U in third place among AC1900 routers tested, below the NETGEAR R7000 Nighthawk in first and Linksys WRT1900AC in second.

Benchmark Summary

Wireless Performance – Comparative

I pulled the NETGEAR R7000, ASUS RT-AC68U, Linksys WRT1900AC into a wireless performance comparison.

2.4 GHz downlink shows little significant difference among the group. The most I can say is the DIR-880L tends to run on the lower side of the group. It also has the lowest throughput at 63 dB, but none of the products are producing much bandwidth at that point anyway.

2.4 GHz Downlink Throughput vs. Attenuation

2.4 GHz Downlink Throughput vs. Attenuation

The 2.4 GHz uplink plot follows a similar pattern, with the 880L tracking lower with the Linksys WRT1900AC, which has the best throughput with strong signals from 0 to 24 dB.

2.4 GHz Uplink Throughput vs. Attenuation

2.4 GHz Uplink Throughput vs. Attenuation

The 5 GHz downlink profile shows the 880L again running on the low side of the group. Along with the ASUS RT-AC68U, it disconnects 3 dB earlier than the R7000 and Linksys WRT1900AC.

The same trend is also seen in the 5 GHz uplink profile, i.e. tracking with the ASUS and disconnecting at the same attenuation.

Closing Thoughts

D-Link’s DIR-880L is a late entry to a market that has already decided on its favorites. With the focus moving on to this year’s early-adopter bait—AC2350 and AC3200 routers—AC1900 class products are fast becoming last year’s news. But don’t expect AC1900 bargains just yet.

Router makers have also moved on to higher price points north of $250 for both new router classes and at least early buyers are showing no reluctance to part with bigger bucks in hopes of improved wireless performance. (Sighhhh… foolish humans….) So with no downward price pressure, makers are leaving prices pretty much as they are until TP-LINK or someone else comes in with a decent performance AC1900 router at a more aggressive price. Don’t hold your breath for this, though, since TP-LINK is still birthing its second AC1750 class router, the Archer C8 that has yet to ship.

The bottom line is there is no compelling reason to not buy the DIR-880L. But there is no big thing making it a must-have, either.
