hi all,
I have 3 AV 200 powerline adapter. I configured and connected with 3 different WiFi network. I can see all of them through the connection tool but... after 20-30 minutes they start disappearing loosing the connection to the router. I really don't know what to do, the connection has never been stable for more the 20/30 minutes. The only AV200 that works is the one that is directly connected to the router (obliviously).
When they are connected, if I go to the "Station setting" page in the Powerline menu, I can see that the others adapter in range keep on switching form online to offline and then, after minutes, to "unknown status".

thanks in advice :)

regards
Marco
