Features

The V2's feature set is the same as V1's. But the admin interface has been gussied up a bit and split into Basic and Advanced levels. The Status page you land at upon login shown below is much prettier. You can't click on anything in the right side, however. All menu selection is done via the left-side menu bar.

The V1 review covers the feature set nicely, so I won't repeat that here. For more info, use the emulator and download the user manual.

Storage Performance

I ran Windows filecopy tests using the standard NAS testbed to the 812DRUV2 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.

  TEW-812DRUV2 TEW-812DRUV1 D-Link DIR-868L Buffalo
WZR-1750DHP
FAT32 Write (MBytes/s) 8.1 5.0 16 21
FAT32 Read (MBytes/s) 17.2 6.4 27 38
NTFS Write (MBytes/s) 4.8 2.2 11.5 N/A
NTFS Read (MBytes/s) 12.1 5.5 13.8 N/A
Table 2: File copy throughput

Table 2 pulls in the V1 and two other AC1750 class routers with USB 3.0 ports. It shows the V2's file copy performance has definitely improved for both NTFS and FAT32 formated drives. But, except for NTFS read, it doesn't really produce the performance that other vendors can coax from the same Broadcom SoC.

Routing Performance

Routing performance for the 812DRUV2 using our standard test method is summarized in Table 3 beside the V1's numbers. The V2's results are mixed, with lower unidirectional throughput, but much-improved bidirectional (simultaneous). Maximum simultaneous connection handling has also gotten a nice bump up from the V1's 8K limit.

Test Description TEW-812DRUV2 TEW-812DRUV1
WAN - LAN Throughput - (Mbps) 563 817
LAN - WAN Throughput - (Mbps) 712 851
Total Simultaneous Throughput - (Mbps) 722 467
Maximum Simultaneous Connections 14,989 8,192
Firmware Version
2.0.2.0, Oct 18, 2013
1.0.8.0
Table 4: Routing throughput

The IxChariot composite plot for the unidirectional tests shows steady throughput for the most part, with upward jumps in the uplink plot and periodic significant dips for downlink.

The simultaneous up and downlink plot below shows a definite preference for uplink traffic when heavily loaded.

Wireless Performance

Like the V1, the 812DRUV2 is not Wi-Fi Certified. It defaulted Auto channel and 20 MHz B/W mode on 2.4 GHz and 80 MHz mode on 5 GHz 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 had better luck running the 40 MHz Coexistence and Fat channel intolerant tests, than I had with the V1, but neither passed. In both cases, the router continued to operate in 40 MHz mode.

The WPS test failed to prompt to initiate either a WPS PIN or pushbutton WPS session when I selected either of the SSIDs with a Win 7 notebook.

For throughput testing, all tests were run using our standard wireless test process with 2.0.2.0, Oct 18, 2013 version firmware loaded. The router was first reset to factory defaults, then Channel 6 and 20 MHz B/W mode was set for 2.4 GHz and Channel 153 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 front side of the router facing the chamber antennas.

The Benchmark Summary below shows the average of throughput measurements made in all test locations. If you filter the 2.4 GHz downlink chart for AC1750 routers, you'll find both the V1 and V2 near the bottom of the chart. You'll also find the same for 2.4 GHz uplink. In fact, the only time the V2 moves up significantly from the cellar is for 5 GHz uplink, where it rises to fifth position from the bottom.
