The reviews I've read in the consumer computer mags all seem to agree  
that the speed claims for A/C wiring type networking devices are  
significantly exaggerated.

But so are the claims for just about any consumer device in terms of  
speed, capacity, etc.

Heck, the industry can't even agree on what a "gigabyte" is.

You will never, for example, see an 802.11g link transfer at 54Mb, or  
a USB 2.0 run at 480 Mb, it just doesn't (and can't) happen. Why they  
are allowed to get away with this crap escapes me.

I have read suggestions that you try and get all devices on the same  
phase, don't use other A/C wiring type devices (X-10, "wireless"  
intercoms, modem jacks etc.) and try and keep the distances as short  
as possible. D.C. motors, dimmers, speed controls and other things  
that put noise on the power lines are to be avoided as well. (easy to  
say I know).

Still, your performance seems less than what might well be expected.
