Figure 11 shows that the results from my four location test were so consistent, that I had to double check to make sure that I didn't accidently forget to run some of the tests! I also checked performance with 128 bit WEP enabled and saw no throughput change.

I should note that the test results are taken through the router, since the B-4000's V-LAN feature prevents all communication between LAN-side clients. But since routing throughput is more than 3X the speed of the wireless connection, I can safely say these results truly reflect the actual wireless speed.
