Table 1: Routing throughput
Throughput is pretty steady for both unidirectional and simultaneous tests. Note also that in the simultaneous test, both up and downlink throughput is the same.

The Maximum Simultaneous Session test topped out at 14,976, which is close enough to the 14,983 sessions measured for the TEW-691GR to be considered the same.
Wireless Performance - 2.4 GHz Two Stream
The 692GR is not Wi-Fi Certified, but it properly defaulted to 20 MHz bandwidth mode on the 2.4 GHz radio on power-up, as it also did for the 5 GHz band.
I was able to run a Wi-Fi Protected Setup (WPS) pushbutton session with my Win 7 client that resulted in a WPA2/AES secured connection to the 2.4 GHz radio. All tests were run with this secured connection using our new four-location wireless test process.
First, let's look at the Benchmark Summary in Figure 6. The main takeaway here is that there isn't a significant difference in two and three stream throughput when averaged across the four locations tested.

Although N routers that support three-streams in 2.4 GHz are harder to come by than those that provide this higher rate in the 5 GHz band, we've now got a few in the Charts database to compare: the TRENDnet TEW-691GR; D-Link DIR-665; and Gen 5 Apple Airport Extreme.
Figure 7 shows the wireless Performance Table for the four routers for 2.4 GHz and 20 MHz mode and neither TRENDnet turns in a particularly noteworthy showing.

The real standout here is the inability of both TRENDnets to get enough throughput in Location F to run the IxChariot test. The odd thing is that in some cases the Intel 5300 client still maintained connection to the 692GR. But there wasn't a good enough connection to even run a ping.
I'm not going to show a 40 MHz mode table because the Apple doesn't support that mode and it doesn't really provide that much more insight into relative performance.
I'll note that best case throughput for the 692GR was 70 Mbps in Location A running downlink in 40 MHz bandwidth mode. And when running simultaneous up and downlink tests in that mode, I measured 91 Mbps of total wireless throughput.
Turning to the IxChariot plots reveals some interesting performance quirks. Figure 8 shows that even with strong signals, throughput is anything but nice and steady with periodic significant downward spikes. While it's possible that this is an artifact from IxChariot, I doubt it because I use the same test file size on other products and don't see this behavior.

The other thing you'll see in this and most every other plot is the multi-second throughput ramp-up at the start of each run. This is definitely baked into the performance cake since I was unable to remove it with multiple test reruns.
