Well the good news is that the previous owner of my house says that the adsl service is good for 8Mb/s but I now have to wait a week to be connected.
Now the question is, how good is the mains network. ;o)
Do the devices need software configuration ? I have an ancient laptop that should do the job.
Yes, you need to configure a key because the mains traffic is encoded (there's a good chance some of it leaks past your transformer and into the rest of the street). :o)
In Devolo's case there is a configuration tool for Windows and Mac IIRC. (The stuff I have is from the 14 mbit era, so I'm not sure whether anything changed in their newer stuff).
