I don't believe this to be true.. 10mb: 9.77 MB 598.43 kB/s Thats EAISLY 4.8mbs, and it was bursting up to 7 or so. You lose 20-30% due to radio overhead, but it's clearly NOT only 3mbs. This was with a cisco card and a cisco AP in 802.11b mode. The comments about microwaves are dead on though, and what are worse are the new 2.4ghz cordless phones - but those will effect G as much as B.
