I posted about my early experiences with this technology about 8 months ago here and here.

At the time of these posts the apartment was perfectly empty except for the adapter and the notebook I was using.
Now, after a full renovation including the electrical infrastructure, it is a real home with all the associated devices and appliances connected and operating.
Another important change is that, due to the limits of the electrical tubing connecting upper and lower level, I had to connect the two levels using the same technology and now I have in place 4 adapters from the same manufacturer.

What I read right now in the monitor from the upper level is:
110 Mbit/s to the lower level
70 Mbit/s to the garage
60 Mbit/s to the underground room.

To the garage what I get at the application level moving data to the garage is about 3MB/s (a bit shy of 30Mbit/s) when using a backup program targeting a share on the LS220D and about half of this when using directly a samba share on the same device to move files with windows explorer.

The number reported are in the lowest range of the day and they can easily get 30% better than this depending on the amount of electrical noise tha is injected on the line from the other apartments on my building.

Marketing proves to be even more distant from the reality than I already complained about. But it is still better than WiFi in my environment.

I’m experiencing some significant brownouts during the day with the worst quality during the evening and at lunch time.
This might also be a factor, but I have opened a complaint and in a couple of months should be addressed by my electricity distribution company.
