Throughput vs. Distance
I ran my four-location throughput test using IXIA's Chariot for 11a, 11a Turbo, and 11g operation. Figure 10 shows the 11g mode results.

For comparison, here's the 11g plot from the Broadcom / Atheros based Linksys WRT55AG review.

No comparison, eh? Granted the WRT55AG was tested with draft-11g firmware, but even if you use the throughput results from its 11g-only sibling, the WRT54G, the FWAG still has superior overall throughput vs. range, but is at a slight disadvantage for best-case average throughput.
