During installation, there was the problem that when the TV (Plasma Panasonic 42PZ85) rapidly went the connection speed in the basement.
In numbers: 5 Mbps instead of 30 Mbps, which is fed by the Internet provider. I turned off the TV, I came up with the 30 MBit.
Several Umsteckversuche (one at outlet, power strip, in series, etc.) of your TV, PS3 and unfortunately the dLAN adapters brought no significant improvement.
The telephone support from Devolo recommended me the dLAN adapter as far as possible to connect from the television or a so-called "PLC Blocking Filter" (cost: about 40) interpose (although in the dLAN adapter 200 AVplus already a filter is installed). Apparently sends the power supply of my plasma TV from strong electrical noise that interfere with dLAN connection considerably.
I now have so resorted to me that I have connected the dLAN adapter on the other end of the living room and bridge the distance with a 15m LAN cable. So I come at least 25 Mbps. That's enough for me.
Conclusion:
Overall, good product and a good alternative to Wi-Fi.
However, interference can bring by neighboring electrical appliances, the system pretty shaken.
Who can not attach far from a possible source of interference the dLAN adapters, will not be satisfied with the dLAN AVplus Starter Kit.
