current Cyber2lz favorite in Powerline adapters is the
Powerline Ethernet Bridge. This
converter takes an 802.3 signal and "bridges"
it onto the electrical wires of the premise. Complimentary
Ethernet equipment with a valid IP address takes that broadcast signal
off the premise wiring and feeds it to the attached client
device as an 802.3 (Ethernet) packet stream. This device can be
any valid Ethernet equipment, including computers, switches,
printers and more.
