Mixing it Up - Super-G plus XR
My next mixed mode test mixed a NETGEAR WG511U Super-G plus XR card with the True MIMO pair. Figure 20 once again shows that the Super-G client's throughput takes it on the chin, even though the True MIMO pair once again tries to accomodate by dropping its throughput.

But Figure 21 shows a markedly different result when I ran the same test in the downlink direction. The True MIMO pair once again shifts throughput down when the Super G pair starts. But this time, the Super G pair moves up to over 10Mbps while the True MIMO pair moves down further to around 20Mbps. Although this is far from equal sharing of thoughput, it's much better than obtained in the uplink direction.

Although the plots aren't shown, I found that this same more-equitable bandwidth sharing in the downlink direction also occurs when the Super-G pair starts first.
