TRENDnet TEW-811DRU Status page

I ran through the admin interface for both the TEW-811DRU and TEW-812DRU. Although the look is somewhat different, the options appear to still be nearly identical and everything that was mentioned in the TEW-812DRU review still applies.

For a full feature tour, use the emulator and download the user manual.

Wireless Features

Table 2 summarizes the basic wireless setting modes and channels supported.

Setting 2.4 GHz 5 GHz

Table 2: Wireless settings summary

Browsing through the wireless setup menus I also found that each radio could be disabled, but not on a schedule. Advanced wireless features included an XPress Technology enable (default enabled), but no transmit power adjust. Guest networks are available on each radio that have their own security modes and options for isolating wireless clients from each other and limiting client access to internet access only.

In addition to the manual wireless security settings shown above, the router supports WPS PIN and pushbutton setup modes. You also can define schedules for turning each radio on and off for added security. Note there is no WEP option listed in the security selectors, even when disabling the 802.11n mode.

Storage Performance

The TEW-811DRU supports file sharing via SMB and FTP, and it also supports printer sharing. There are no media servers.

We ran Windows filecopy tests using the standard NAS testbed to the TEW-811DRU 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. Table 3 shows the results along with some from other draft 11ac routers with USB 2.0 ports.

FAT32 Write (MBytes/s) 8.9 7.8 5.0
FAT32 Read (MBytes/s) 10.8 10.5 6.4
NTFS Write (MBytes/s) 3.6 9.9 2.2
NTFS Read (MBytes/s) 9.4 10.5 5.5
Table 3: File copy throughput

You can see here that if you are reading / writing FAT32, the TEW-811DRU does comparatively well. But for all other tests, the NETGEAR R6100 is the best of this bunch. Note that the 811 is slightly better than the more expensive 812 for all the benchmarks. This is most likely due to the more powerful second generation SoC in the 811.

Routing Performance

Routing throughput was measured running V1.0.2.0 firmware, using our standard router test process. Table 4 summarizes the results. As we have come to expect from Broadcom-based AC routers, throughput is well above 500 Mbps in each direction.

Test Description TEW-811DRU
WAN - LAN 575.1 Mbps
LAN - WAN 669.2 Mbps
Total Simultaneous 728.4 Mbps
Maximum Simultaneous Connections 14,992
Firmware Version V1.0.2.0
Table 4: Routing throughput

We are now separating the unidirectional and simultaneous IxChariot throughput plots for clarity. The composite unidirectional plot below shows a significant amount of variation in both directions, with some occasional dips down to 100 - 200 Mbps.

The simultaneous up/downlink test shows some very large variances in throughput, with speeds dropping down into the 10/100 range in some cases and up and downlink seeming to battle for dominance. However, given the > 500 Mbps of routing throughput, this variation is unlikely to be a problem in actual use.
