Like most routers in its class, the 812DRU supports sharing USB storage and printers. And, consistent with its last-generation design, the USB port is 2.0 vs. 3.0. The screenshot below shows that files can be shared via SMB and FTP (no S-FTP), with up to four different user accounts defined. Unlike some of its competition, however, the 812DRU has no media servers.

I ran Windows filecopy tests using the standard NAS testbed to the 812DRU with our USB standard drive (Startech USB 3.0 eSATA to SATA Hard Drive Docking Station (SATDOCKU3SEF) containing a WD Velociraptor WD3000HLFS 300 GB drive) formatted in FAT32 and NTFS.
|FAT32 Write (MBytes/s)||5.0||9.0||7.3||8.6|
|FAT32 Read (MBytes/s)||6.4||9.9||11.8||10.2|
|NTFS Write (MBytes/s)||2.2||13.5||8.4||11.3|
|NTFS Read (MBytes/s)||5.5||9.4||8.7||10.3|
Table 3: File copy throughput
Table 3 shows the results along with some from other draft 11ac routers with the same first-generation Broadcom design and USB 2.0 ports. The TRENDnet is slower across the board than the other three products. It is particularly poky for writes to an NTFS-formatted drive, which most people are likely to use.
Routing performance for the 812DRU using our standard test method is summarized in Table 4.
|Test Description||Throughput - (Mbps)|
|WAN - LAN||817|
|LAN - WAN||851|
|Maximum Simultaneous Connections||8,192|
Table 4: Routing throughput
As I've found with other draft 802.11ac routers recently, unidirectional throughput is north of 800 Mbps. But when tests are run in both directions at the same time, the battle for dominance pushes total throughput down to, in this case, 467 Mbps, as the IxChariot composite plot below shows.
TRENDnet TEW-812DRU routing throughput
The Maximum Simultaneous Session test topped out at 8,192, which is low compared to most other recently-tested routers that hit the limit of our test method up near 30,000 sessions.
The 812DRU is not Wi-Fi Certified. It defaulted Auto channel and 20 MHz B/W mode on both 2.4 and 5 GHz radios 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.
I tried to run 40 MHz Coexistence and Fat channel intolerant tests, but could not get the ASUS PCE-AC66U test client to connect with the router with its 2.4 GHz radio set to 40 MHz bandwidth mode. To rule out a problem with the ASUS adapter, I also tried and failed to connect a Lenovo X220i notebook with Intel Centrino 6300 N450 adapter.
I didn't have much luck trying to connect via WPS, either. When I selected either of the 812DRU's SSIDs with a Win 7 notebook, it didn't give me a prompt to initiate either a WPS PIN or pushbutton WPS session. So I set up a WPA2/AES connection manually and used it for all testing using our new wireless test process and 18.104.22.168 version firmware loaded.
The router was first reset to factory defaults and Channel 6 was set for 2.4 GHz and Channel 153 for 5 GHz. 20 MHz B/W mode was set for 2.4 GHz and 80 MHz B/W mode was set for 5 GHz. The router was positioned 8" from the chamber antennas in all test positions. The 0° position had the right side of the router (viewed from the front panel) facing the chamber antennas.
The retest Benchmark Summary below from the new Consolidated benchmark process shows the average of throughput measurements made in all test locations. The 2.4 GHz values in the summary correspond to 2.4 GHz values (20 MHz B/W) and the 5 GHz values correspond to the 80 MHz B/W - 3 stream values measured with the previous test methodology.
Comparing average 2.4 GHz benchmark values with other AC1750 routers in the Charts, the 812DRU's 58 Mbps and 55 Mbps downlink and uplink averages are almost half the top-ranked ASUS RT-AC66U. Of the two directions, the 812DRU's uplink results are better. The simultaneous up/downlink test also turned in relatively low throughput compared to other AC1750 class routers tested, only 128 Mbps.
The story is similar for 5 GHz, with 143 Mbps and 108 Mbps downlink and uplink averages running about half the top-ranked ASUS RT-AC66U. In this band, the 812DRU's downlink average results were better, as was its simultaneous up/downlink throughput of 548 Mbps that ranked it in the #3 slot for this benchmark.
