You may be sick of hearing about "the Cloud" by now, but you might as well get used to it. The Cloud has invaded NASes and networked media players and it’s now starting to engulf the lowly router. The first example of this new genus is D-Link’s DIR-605L Cloud Router.

You might expect that a first-in-category product would come at a premium price. But D-Link has taken a different approach by starting with an entry-level 802.11bgn router with 10/100 Ethernet ports, adding a handful of monitoring features available via its existing mydlink.com portal and pricing it under $50.

I covered 605L’s cloud features in a separate SmallCloudBuilder article. This review will cover its feature set and performance.

The 605L is more physically similar to D-Link’s DHP-1320 powerline router, than its "Amplifi" siblings like the DIR-827 and DIR-657. The small, well-ventilated case is made to sit on a desktop and has no bottom-cover mounting slots and no bundled vertical-mount stand. The dual non-upgradeable 5 dBi antennas seem to loom over the smallish case, but are light enough to not cause it to tip over backwards.

The front and rear panel callouts taken from the user manual don’t need much explanation. As befits a sub-$50 router, all ports are 10/100, not Gigabit and there is nary a USB port for storage or printer sharing.

The inside shot from the FCC ID docs below isn’t great, but it’s clear enough to reveal that Realtek was tapped to power the 605L.

Other FCC photos had close-ups of all the key components, which are summarized in Table 1.

The design is very similar to the Amped R10000G that we just reviewed; actually more like its R10000 10/100 sibling. Note that the 605L doesn’t have separate transmit power amplifiers like the Amped routers. But it was able to run all tests in Location F.


Even though it is based on a different chipset than D-Link’s other products, the admin interface has the classic D-Link router look shown in the Internet Connection screen below.

  • Schedulable allow/deny MAC filtering
  • Non-schedulable deny MAC ACL

Missing features

  • IPv6 support
  • HTTPs admin access
  • Wireless guest access
  • Wireless on / off schedule or physical wireless disable button
  • Wireless client isolation
  • WPA/WPA2 Enterprise (RADIUS) support

Thirty second reboots are required to save setting changes. But at least you can make changes on multiple screens and save once. Given D-Link’s aggressiveness in supporting IPv6, it was a surprise to see support missing on the 605L.

D-Link hasn’t posted an emulator for the 605L. So I’ve posted most of the key screens in the gallery with explanatory captions.

Easy Setup

This is pretty basic as a setup wizard. You get to look at it every time you log in.

Internet Connection

The usual suspects for WAN connection are supported (Static IP, DHCP, PPPoE, PPTP) as well as L2TP

Basic Wireless

The Manual Wireless setup screen combines channel and wireless security settings. You need to go to the Advanced Wireless page to change bandwidth mode–a good choice

Parental Controls

Unlike other D-Link routers, there is not a built-in option to use OpenDNS for parental control. Instead you get a measly 10 URL filters which can be set to allow only or deny only.

Advanced Port Fwd

You get 24 of these port forward rules. You can set public and private ports separately and TCP/UDP/Any traffic type. But you cannot schedule the rules

App Rules

Similar deal for triggered ports, i.e. no scheduling

MAC and ACL filters

Not sure why there are two functions that appear to do the same thing. Except MAC filters are schedulable, ACL filters are not.

Traffic Control

You get up and downlink bandwidth-based QoS. But bandwidth is controlled by IP, not by service port and IP.


Miscellaneous firewall settings. But you also get 50 schedulable firewall rules that can be used for in and outbound service port filtering.

Advanced Wireless

Here are the advanced Wireless settings. Guest networks are not among them. But lots of controls you shouldn’t mess with are.

Advanced Network

More miscellaneous settings. Note the WAN port speed and multicast controls. No IPv6, though.

System Check

The handy-dandy connection checker that comes with Realtek-based switches


Here are those schedules I have been referring to. You get 33 of them.

Log settings

Log setup including syslog support

mydlink Events

These provide a hint of what you’ll see via the mydlink.com cloud portal.

Log screen

The built-in log is not pretty, but it is there


A view of all sessions that the firewall sees as open

Wireless status

Nothing fancy here

Routing Performance

Routing throughput running the latest 1.11 firmware and our router test process measured 87 Mbps WAN to LAN, 86 Mbps LAN to WAN and 133 Mbps total with up and down tests running simultaneously. This is a bit lower than most other routers that I judge 100 Mbps "wire speed". But, in reality, you would be hard pressed to see a difference.

Maximum simultaneous connections topped out at a relatively low 6,483. But again, this number is more than sufficient for a home/SOHO router.

The IxChariot plot below shows a moderate amount of throughput variation under the high continuous-traffic load of our test scripts.

Wireless Performance

The DIR-605L is Wi-Fi Certified and properly defaulted to 20 MHz bandwidth mode on power-up. I successfully ran a Wi-Fi Protected Setup (WPS) PIN session that resulted in a WPA2/AES secured connection. The WPS session took a bit longer than I normally see with other routers to complete and I think the router had to do a 30 second reboot to store the new settings. All wireless performance tests were run with this secured connection using our wireless test process and our standard Channel 1 setting.

To compare performance, I ran a 2.4 GHz Wireless Performance table with the 605L and another recently-reviewed $50 single-band router, the TP-LINK TL-WR1043ND. The 605L’s uplink throughput is generally higher than the TP-LINK’s and it had higher Location D throughput (moderate-to-low signal level) in three out of four tests runs.

Wireless Performance Table

Wireless Performance Table

Throughput stability was generally good with no multi-second deep dropouts observed or large throughput jumps due to excessive link rate hunting. Top throughput of 99 Mbps was measured in Location A with simultaneous up and downlink tests running in Auto 20/40 MHz. mode.

Closing Thoughts

The DIR-605L is a decent performer for wired routing throughput with wireless performance better than many routers costing twice as much. Yet, when stacked up against the features of the equally-priced TP-LINK TL-WR1043ND, it doesn’t look as appealing.

For the same money, the TP-LINK has Gigabit Ethernet ports, upgradeable antennas and can share a USB drive via FTP or UPnP, while matching the 605L with WDS support and up/downlink bandwidth-based QoS. But the D-Link still has the edge on the TP-LINK in wireless performance.

The real reason you’d opt for the DIR-605L, however, is its cloud features. As I’ve mentioned at the top of the review, those features mainly focus on letting you monitor router status and where your users are going on the web, so they won’t knock your socks off. But I’ve provided the full details over on SmallCloudBuilder, so, be sure to read the rest of the story there.
