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

<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!</p>
<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.</p>

<div>A simpler version of this is something I am looking for. One (maybe a couple of backups too) cable from the BT hub connecting to a WiFi unit in the meeting room. Probably Cat5. Will an Older Home Hub be ok, or should i look at something else? There seem to be quite a few Cisco Airnet AP's on ebay reasonably cheap.</div>
