I've been field testing with these two units in a project I'm doing for my
church (discussed earlier). Of course, the DI-524 is a 54Mbps "g" router,
while the DI-614 is a "b." While my tests do support that the 524 is
faster, I can state unequivocally that the 524 is much, much weaker as a
wireless transmitter. When used in the same area with the same antenna(s),
the 524 causes my signal at one particular workstation to drop to +/- 20%,
compared to +/- 45% with the 614. The measurements are via the Dlink
utility.
