PLE400, PLW400.

The power wiring is not used as an antenna, it is used to directly transmit
signals.  The wiring does leak eletromagnetic noise because of the powerline
transmission, but this is not an useful function, it is an undesireable side

Do note that you need to connect the PLE400 and PLW400 to the *same
electrical circuit* (i.e. below the same circuit breaker), and that it will
not always work well when you have other electrical noise sources around.

Probably yes.  The information on the PLW400 is not clear enough, but it
really should be acting as a standalone AP, and therefore it is supposed to
be far better than the bridging the RE1000 does (especially with a 802.11g
device like the WRT54G).

However, please be advised that it would be better to use CAT5e ethernet
wiring and several access points directly connected to a central router,
instead.  Powerline transmission is much worse a source of eletromagnetic
noise than fast ethernet over CAT5e cabling (especially if you use CAT5e STP
cabling), and it is much more succeptible to outside interference as well
(when compared to properly installed CAT5e STP cabling).
