My neighborhood is full of WiFi networks. Some of my neighbors' routers jump from channel to channel, causing intermittent interference.<br /><br />I have a lot of devices in my house. Any device that is relatively stationary (printer, Z-wave controller, PC, IP camera) is plugged into one of these little gems, as they are immune to WiFi interference. Set up is easy. Just follow the directions. I have found that they will not work if plugged into surge suppressors (the instructions said so, but I had to try) or z-wave controlled outlets (these create interference).<br /><br />The only reason I don't give these adapters five stars is that they have to be unplugged and replugged periodically (monthly, quarterly?) to keep the network up and running. That's my first shot at troubleshooting if a Powerline AV connected device loses network connectivity. Start by unplugging the one connected to your router, then go around and unplug/replug the 'client' adapters.
In a world gone mad with WiFi signals...
