Updated 2/12/16: Product is not Wi-Fi Certified
The TRENDnet TEW-827DRU is not Wi-Fi Certified. It was tested using the Revision 8 Wireless test process with 1.00b011 (1.00 17 Nov 2015)firmware loaded. The router comes with WPS enabled. A Windows 8 notebook successfully connected to each radio via WPS pushbutton session that resulted in WPA2/AES connections.
The router defaults to different, router-unique SSIDs, auto channel select and 20 MHz channel width for 2.4 GHz, and auto channel select and auto channel width for 5 GHz as shown below. It also supports Channel 165 in the 5 GHz high band.
TRENDnet TEW-827DRU Wireless Defaults
For performance testing, the router was first reset to factory defaults. The 2.4 GHz radio was set to Channel 6 and 20 MHz bandwidth mode. The 5 GHz radio was set to Channel 153 and 80 MHz channel width to enable 802.11ac link rates. The AC1900 class NETGEAR R7000 bridge mode standard test client was connected using WPA2/AES encryption. StreamBoost, Qualcomm's QoS, enabled by default, was disabled for all testing.
Our standard practice is to center the router under test's antennas on the turntable, both front-to-back and side-to-side in the chamber. This method is intended to keep maximum distance between the router under test and chamber antennas as the router rotates during test. The photo below shows the router in position in the octoScope test chamber.

2.4 GHz downlink performance shows the TP-LINK Archer C2600 with a clear throughput advantage up to 42 dB of attenuation, where its curve joins the Linksys' for the rest of the test range. The Linksys and the TRENDnet routers track each other closely throughout the entire range.
2.4 GHz Downlink Throughput vs. Attenuation
2.4 GHz uplink shows the TEW-827DRU with a significant performance advantage over the other three routers out to about 27 dB of attenuation. From about 30 dB out to the end of the test range, the TRENDnet and Linksys track each other very closely. Surprisingly, the Linksys started out with much lower throughput with strong signal strength than any of the other three routers out to about 15 dB of attenuation. From 15dB to 30 dB, the performance of the Linksys remained flat (constant), but still lower than the TRENDnet.
2.4 GHz Uplink Throughput vs. Attenuation
The 5 GHz downlink benchmark shows the TRENDnet starting off with poorer performance than the Linksys or TP-LINK with strong signal strength out to about 12 dB of attenuation. Beyond 15 dB of attenuation, the TRENDnet trailed only the Linksys for the balance of the test. The poorly performing Amped RTA2600 broke connection after the 27 dB test.
5 GHz Downlink Throughput vs. Attenuation
5 GHz uplink shows some separation at lower attenuation (stronger signal) levels to the mid-teens, then all four tracking closely through the rest of the test run.
5 GHz Uplink Throughput vs. Attenuation
The takeaway for wireless performance is the Archer C2600 may deliver higher 2.4 GHz downlink throughput than its competition with strong signals whereas the TRENDnet TEW-827DRU had an advantage for 2.4 GHz uplink. For 5 GHz, three of the routers had very similar performance for downlink and uplink. The clear loser for 5 GHz performance in this comparison is the Amped Wireless RTA2600, because it dropped its connections significantly earlier than the other routers.
