can't say for "boosted" 802.11g kit,
as I have a pre-N setup which does achieve more then 54Mbps.
My crude method is to tranfer several large (>>4 Mb) video files and a stopwatch.
Is there a free utility program which can do a better job of measuring useable data transfer rates?
Not sure how the "boosted" G kit would get above 54Mbps though. Perhaps the claim is for 30+% greater real data transfer rates which approaches 54Mbps via a higher transmitting power?
