Wireless Performance - 2.4 GHz Two Stream

To look at the four main test groups, a bit of competitive comparison helps. I chose the D-Link DIR-665 and TRENDnet TEW-692GR, but left out the 5th Generation Apple Airport Extreme because it doesn't support 40 MHz mode in 2.4 GHz.

Figure 7 shows the wireless Performance Table for 2.4 GHz and 20 MHz mode. You can clearly see the terrible performance noted earlier running downlink. Uplink performance is more typical of what you should see.

Figure 8's IxChariot plots summary clearly shows the very unstable throughput that is responsible for the 4500's overall poor 2.4 GHz downlink performance in all locations except the weakest signal Location F .

Wireless Performance - 2.4 GHz, Three Stream

Figure 9 shows the wireless Performance Table for 2.4 GHz using the Intel 6300 Ultimate N three-stream client. The 4500 clearly does better in three stream and particularly in medium-to-low signal Location D running downlink.

Figure 10 shows the IxChariot plots for 20 MHz mode downlink in three-stream mode. The plots here are much better, with relatively low variation and only a few large, but brief, dropouts.
