got 3 homeplugs on a home network -

when (for testing purposes) I plug a fourth in to a socket near where
an existing homeplug is plugged in, one of the other distant homeplugs
stops working properly (IP cam - no picture). But if I plug the fourth
one into a socket further round the *same 240v circuit* as before- all
is well.....???? any clues/thoughts please?

Are any of the homeplugs in sockets that are spurs (or 4way extension
leads) rather than directly on the ring? sounds like some sort of
reflection issue ... after all the mains is acting as an unterminated bus.

mmm interesting.... the remote ip cam (that goes awol when the fourth
homeplug is plugged in) is on a 4gang lead,
another homeplug is in a 6gang lead on a desktop, and the router's
homeplug is in another 4gang lead....

NB they don;t all go down - just appears to be the IP cam homeplug
that fails?

Is that a "requirement" that they plug straight into a "direct circuit
fed mains wall socket" ?? (for want of a better description!)

AFAIK that's just a performance matter. I've never had a problem using
extension leads.

When I had a problem with four devolo homeplugs their tech support
people asked me to plug them all into the same extension lead in order
to sort out the problem. So the stern warnings in the manual don't
appear to mean much to them.

Not a 'requirement', but I've always seen it described as 'recommended'.

No link, but it's been in the instructions for the three different
brands I've used over the past few years.

The only reason for it to be "recommended" is that some extension leads
have corroded contacts in the socket because people use them in places
where dirt and damp are common. Also each extra plug and socket in the
chain result in attenuation of the signal causing performance issues.
There's no black magic that causes a plug to mystically misbehave, run
rogue and shut down other homeplugs if it's used on an extension.

TBH, I'd get all the plugs, put them on the same extension, jack the PC
into one of them and flash them all to the current firmware release.
Then assign a new shared secret to them all and that will eliminate
firmware incompatibility or problems with passwords.

yeah done that - all on lastest firmware, all same make, all same
pwds...issue remains :(

RF is magic, not science.

As anyone who has dealt with it intimately can tell you.
