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
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.

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.
