Wireless Performance Overview

The DIR-827 is Wi-Fi Certified, but both bands defaulted to Auto 20/40 Channel Width upon power-up. So if you're going to use the 2.4 GHz band in an area with lots of networks, be sure to set the Channel Width to 20 MHz to avoid spectrum-hogging.

I successfully ran a Wi-Fi Protected Setup (WPS) session with a Win 7 client by entering the WPS code found on the router's bottom label. The WPS session completed quickly and resulted in a WPA2/AES secured connection with the same WPA2 pre-shared key set for both radios. All tests were run with this secured connection using our current wireless test process.

One important note is that when I entered a network name (SSID) as prompted by the Windows WPS wizard, both radios were set to the same SSID! This isn't much help if you have dual-band clients, so you'll have to go back and manually set each radio to a unique SSID so that you can select the band you connect to. The router comes with dlink set for the 2.4 GHz SSID and dlink_media for 5 GHz.

I ran a 2.4 GHz Wireless Performance table for the 827 and their most likely competitors, the NETGEAR WNDR3800 and Cisco Linksys E3200. I also included the DIR-657, even though it is single-band, so that you can see how much better the 827 is.

2.4 GHz

The 827 handily beats the 657 in all test locations except the lowest-signal location F. Even though both D-Links use Qualcomm Atheros radios, the 827 is simply a better performer.

The throughput vs. location plots below make it easier to see the differences among the routers.

Throughput stability was generally good with only occaisional deep dropouts observed. As noted above, however, throughput in the lowest signal test location F was very low and I had to start some IxChariot tests multiple times before they would run. Even though it is better than the DIR-657 with strong to medium signals, the 827 is not a router you'd choose if you are trying to stretch your wireless coverage.

The highest throughput with a single test stream of 80 Mbps was obtained in Location A, downlink in Auto 20/40 mode. Running simultaneous up and downlink tests squeezed out higher throughput, 82 Mbps in 20 MHz mode and 118 Mbps in Auto 20/40.
