Powerline kit is heavily dependent on the quality and sanity of
the wiring in a given building. It's potentially an expensive
guess.

<p>There is a massive interference generated by powerline
equipment. I bench-tested one (D-Link) effort that produced
broadband RF crud right up to over 1GHz, interfering with mobile
phones in the vicinity! These things wipe out radio reception in
the building and seldom work as well as advertised. Please avoid
these noise generators at all costs!<br>

<p>I've used wi-fi repeaters successfully to extend coverage
throughout large buildings. The best ones are "dumb" and can
receive on one wi-fi channel and retransmit on another - a
centrally located "master" wi-fi router unit acts as a donor for
all, with the repeaters located radially about it.</p>
<p>If you can run some Cat 5 or Cat 6 cables, the best option of all
is to run <i>cabled</i> wi-fi access points from a central
router. I used twelve discarded BT HH5 units for this - flashed
with DD-WRT - and covered my office building with an absolutely
solid wi-fi signal with no dead areas at all. I put the cabling
and the routers in the false ceilings above the open-plan offices
and got superb coverage. The whole set-up can be administered
from the central router, and the addition of a "Pi-Hole" reduced
the advertising traffic on the network to almost zero! The whole
rig cost <£150, with the biggest cost being the Cat 6 cable.<br>
