Default Re: Powerline ethernet adapters any good? Difference in powerline speed over direct connect Wireless?

Yes, that was for US power stuff (thought about that after I wrote it....)
I wonder from what you said, what is the 380/420 part used for? Is that
similar to the 240 in the US that use two hots and no neutral? (only some
special plugs even have use that higher voltage, all the rest are the lower
120 volt....
From what you said, isn't the 220/240 stuff in most rooms, where you can
plug things in? Those wouldn't seem to need the 3 phase stuff...

At any rate, checked into powerline networking on the netgear website (of
course they have a lot of countries listed, but not greece :( )... Here's
the UK one
http://www.netgear.co.uk/wallplugged...it_hdxb101.php and in the specs
for power it says "Works with 3 prong standard 240 volt electrical
outlets"...

Sorry, that's the closest I can get to an answer for you...
But if it does happen to work in your situation, I can definately say I have
them, have used em, love em, and don't get a commission for saying that :)
