Now that is interesting! I dont know a great deal about homeplugs, but, does that not suggest that Dave and his neighbourgh's wiring are somehow connected?

That isn't correct otherwise you couldn't use them round the house but I thought that you had to be on the same side of the main incomer.

I have read about this happening before.  This is why I don't personally trust anything apart from proper wired ethernet!

How does a duplicate IP address work on the same network?
My suggestion would be change your network from 192.168.0.0 to say 192.168.25.0 or away from anything the router makers use as their default range.

I assume that when you connect to the router it automatically allocates an IP address

There are two types of power cuts that affect me.
One is where the whole area loses power.
The other type, as told to me by a United Utilities CS operator, is that around here houses are fed from the same source, in batches of three houses at a time, so in that type of power cut, I and my neighbour can be without power, the other neighbour will have power !!
They are very good, they tell me why there is a power cut, overvoltage or underground cable fault usually, they tell me the expected recovery time, it is always sooner, they take a mobile number to text me if it will take longer than expected, and quite often soon after power is restored, they will ring me to check everything is OK.
So probably something like that going on...

It's probably the same with mains powered baby alarm units on the same channel.
(So be careful what you get up to in the bedroom ! )
BTW, one neighbour still doesn't encrypt their Wi-fi !

That's to do with electricity supply is 3-phase and the phases have to be balanced so  for most roads every 3rd house is on the same phase.

Re: Security of Powerline Adapters - encryption needed

Which is why you should never run an extension cable into your neighbours property, you may get 415v between the two feeds if on different phases AFAIK.
Say to power a light whilst their power is off, power cut or locally switched off a circuit to repair an appliance for example.

Not mains, but I used to have a totally separate office on a TV Studio site, and (non mains) video feeds came by two different routes, and you got a nasty shock if you touched both earths at the same time, high potential difference, but low current.

No, it's just one of the BT HomeHub's also providing BTOpenzone.

Re: Security of Powerline Adapters - encryption needed

As itsme implies I would expect them to work between two properties if they were on the same phase.
However I don't know what their 'range' is.
My Netgear devices come with a configuration utility which enables me to see the MAC of each unit so I know which one I am connected to Smiley assuming a techy neighbour hasn't devised MAC spoofing for his unit. Undecided
It makes you think though.
Two of my neighbours don't secure their WiFi one of which is Talk Talk with a 17MBs connection Angry

From the Devolo website -
[quote=Devolo dLAN FAQ]the network has to be on the same wiring, and the wire length must not exceed 200 meters. However, different phases are not a problem. Power meters attenuate the signal strongly, but do not necessarily block it.

And if the supply is unbalanced?

How does that work ?
Totally no knowledge of this.
