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.
