As noted above, the feature set of the WZR-1166DHP is identical to the WZR-1750DHP. I'm only going to include one image from the Buffalo UI to give you a sense of the look and feel. Read Scott's full review if you need feature details.

Storage Performance

Windows filecopy tests were run using the standard NAS testbed [NAS test details] connected to a router Gigabit LAN port and the standard USB drive formatted in FAT32 and NTFS connected via the USB 3.0 port.

I updated the table below from the recent ASUS RT-AC56U review to compare the WZR-1166DHP file copy performance with all of the other AC1200 class routers. The ASUS and the D-Link DIR-860L are the only routers to date that have a USB 3.0 port, so all other results are for USB 2.0 ports.

For the Buffalo router, there are no NTFS results as that format isn't supported. For the USB 3.0 tests, the WZR-1166DHP just barely edged out the ASUS RT-AC56U on the FAT32 write tests. For the FAT32 read tests, the ASUS held a clear advantage over the Buffalo device. The Buffalo router, however, edged out the DIR-860L on both the FAT32 read and write tests. Of course, USB 3.0 outperformed USB 2.0 on all devices.

Routing Performance

Routing performance for the WZR1166DHP loaded with 2.09 firmware and using our standard test method is summarized in the table below.

Test Description WZR-1166DHP
WAN - LAN 750.1 Mbps
LAN - WAN 815.9 Mbps
Total Simultaneous 915.1 Mbps
Maximum Simultaneous Connections 4096
Firmware Version 2.09
Routing throughput summary

For both WAN to LAN and the LAN to WAN tests, the WZR-1166DHP ranked fourth for all tested AC1200 class routers. However, for total simultaneous throughput, the WZR1166-DHP moved into third place at 915 Mbps, trailing the D-Link DIR-860L at 1044 Mbps and the top-ranked ASUS RT-AC56U at 1251 Mbps. Simultaneous connections are surprisingly low at only 4,096—the same we measured for the WZR-1750DHP.

For the unidirectional tests the IxChariot chart below shows steady throughput with LAN-WAN (Uplink) being slightly favored. Looking at the plots, you can see very little variation with a very low 95% confidence level.

The simultaneous up/downlink tests show a significant amount of variation in both the LAN to WAN as well as the LAN to WAN speeds. The WZR-1166DHP favored the WAN to LAN (downlink) performance. Note that the average uplink was 411.8 Mbps with downlink averaging 507.3 Mbps. The 95% confidence level showed more variation in the WAN to LAN plot (11.775) as compared to the LAN to WAN plot (8.004). Both of the 95% confidence interval numbers for the simultaneous tests were significantly larger than were seen in the unidirectional tests.
