I initially got pretty excited while testing the 2000, since it was able to connect and pass traffic in all six of my test locations in both the 20 MHz channel and channel-bonded 40 MHz channel modes! But after going back and reviewing my open air test method data, I see that this feat is not a first.
At any rate, I think it's worthy of note that this was done with a product with fixed position, internal antennas and a USB client adapter. I frequently see negative comments that generally attribute poor performance to both these types of products in the SNB Forums and elsewhere. So I hope these results will help dispell these generalizations.
I tested using the open air test method described here using a NETGEAR WN111v2 USB adapter inserted into a Fujitsu P7120 Lifebook (1.2 GHz Intel Pentium M, 504 MB) notebook running WinXP Pro SP2 with all the latest updates. I used the latest 22.214.171.124 driver and NETGEAR's version 126.96.36.199 wireless utility during testing. The router was upgraded to V188.8.131.52NA firmware and I left all factory default settings in place, except to set Channel 1 for 2.4 GHz tests.
Figure 9 shows a composite of downlink throughput tests made at the six test locations in both wireless modes: Up to 145 Mbps; and Up to 300 Mbps. Each column represents the average throughput from a one minute test.
Figure 9: WNR2000 wireless benchmark summary - downlink
As noted earlier, the combination of WNR2000 and WN111V2 reached all six test locations in both 20 and 40 MHz channel modes. The highest downlink throughput of 59.5 Mbps achieved was in Location A (10', same room).
Figure 10 shows a composite of IxChariot plots for all 20 MHz mode downlink tests. While there is throughput variation, it's not as bad as other products that I have tested. Still, it has the effect of reducing average throughput. The 40 MHz mode downlink plot is here if you'd like to look. It looks pretty similar, but with more variation in the Location A test.

Figure 11 pulls together all of the uplink average test results, which generally run lower than downlink speeds. Using 40 MHz mode in uplink seems to help in Locations A, B and C, but doesn't do much in Locations D, E and F.
