If it was illegal solwise would no be selling them.

I nearly missed this piece of stupid paranoia.

Black Hats are all around us are they ?

From what I've read (mainly coming from the stuff Conor has posted
before) the whole CE marking may not necessarily be indicative of the
actual product you have in your hands, depending on whose viewpoint you
look at it from. I know it doesn't give the answer to your issue but
some of it certainly makes interesting reading, for example:

Feel free to be ignorant by all means, if you don't care I'm not going
to argue.

I note you said there had been no work done on the electrics supply, but have
you by chance added any sort of multi-way adapter for 13 A sockets, which
includes a filter?


I do not know much about these HomePlug devices, but if they use the mains
wiring, their efficiency might be reduced if there is a lot of capacitance
across the wiring. A filter would add some capacitance. The adapter could cause
you issues, even if there are no devices at all plugged into it.

I've never used these things myself. The place where I want to get ethernet is
in my garage, and that is on another phase, of the 3-phase supply to my house. I
doubt these things work on 3-phase supplies, where the two computers are on
different phases, though I do not know if that is true.

Go away you foul mouthed silly little man.
Your input to a number of groups is not welcome. Neither is your foul
language
in some groups.
Good job you will never get a licence, no one would speak to you.
You never did say what your registered company number or vat number is.
Companies House has no trace of you, so I passed on the info to a friend
working at HMRC!

He doesn't have a valid UK amateur licence, what he repeats is what he heard
others say. That is why he can't give you any technical explanation!
PLT as it is known uses a number of frequencies to transmit data over mains
wiring. This also radiates for a few hundred feet and can travel some
distance
along a street. OFCOM should say they are illegal as they can cause
problems
with MW radio. You can imagine if you put a MW/SW radio on, it would
cause a data type noise on various frequencies and harmonics. People think
incorrectly that the interference in HF radios is via the mains cable. The
testing
I did showed that the transformer stopped the interference, it was coming in
via the aerials. Using a magnetic loop eliminated the interference.
It shouldn't be down to us licensed amateurs to stop incoming interference,
OFCOM should appy the Law to retailers, similar to how they prosecute
people building pirate equipment for example. PLT devices are illegal to
sell and operate under UK Law, OFCOM refuses to act, I wonder why!
Fortunately a decent matching device on the aerial works wonders when
combined with DSP. So PLT doesn't affect me too much despite the
neighbours using the devices.
I often find computers in unshielded cases cause more problems on HF
than PLT devices! people often confuse PLT noise with computer noise and
once they use a computer by their own radios they soon have problems if
they have no knowledge of EMC. Knowledge of EMC has now been lost
with the downgrading of the requirement for giveaway licences such as
the novice scheme. Nothing like it used to be with two C&G exams and
a morse test at 12 words per minute to operate on HF.
It is clear that standards have dropped from some of the posts about.
Lots of people who class themselves as "technical" but haven't a clue
when they are asked to explain what they look at on Google or see others
posting and just copy it.
Fortunately some of us are Class A amateurs and have a working
knowledge of radio engineering through years of work and designing
products for manufacturers such as Kenwood! Also designing computer
related products that radio amateurs now use every day.

Err, I posted a scan of it on uk.r.a

That "some" doesn't include you, Tiscali idiot.
