Good morning.

Chances are, you do not know what I am referring to... But I decided to understand this; maybe you can help anyway:

I call the box, furnished by our access-provider (OVH), the "ADSL-Box" to avoid a misleading accent on any of its specific functions.

For a test, I plucked the Ethernet-cable, destined to connect a local PC to the ... broadband network (aka "The Internet") to a power-plug ... (wait a moment), that is what D-Link is all about.

Although these D-Link components are reported to last only a few weeks, mine tend to be functional even after over three years. My current configuration is interesting, because I try to connect a computer to the Internet via a power line that is interrupted by two fuse boxes.

In the beginning, I had been told that D-Link signals would not cross the border of these installations, but I quickly noticed that they do!

This time, too, I had immediately Internet access but only for a short while. Afterwards, the connection is interrupted and would not come back. My machine fails continuously to get a new IP lease from the DHCP server on the "ADSL-Box". Any request to bring back the connection is refused.

The scenario is somewhat "esoteric". But maybe someone knows something...

I think your referring to power-line communications. In a nutshell the adapter superimposes the data signal on top of the AC voltage. One can make some logical guesses but no way to know exactly what is happening from afar.

I would not expect the signal to "propagate" through two fuse boxes but there could be other ways the signal is flowing too. You might of just gotten lucky for awhile or there maybe other electrical devices that could be generating noise and interfering with a low signal level.

Thank you michaelk.
I have, myself, only a vague understanding (make that "imagination") of what is going on. But your idea of electrical noise being potentially helpful in establishing temporary connections, seems reasonable.

I will not try to get this running by all means, there is actually not much to gain...

Okay; SOLVED for now.
