Smart plugs like Belkin's Wemo line can definitely make your home feel a whole lot smarter! That said perhaps less so though if it isn't working .
Can you walk us through what it is you're experiencing and what steps you've taken? I don't have any experience working with Wemo products myself but perhaps some of our Resident Experts might be able to assist! @Gdkitty, @Datalink.
While i only have one Wemo device, I have not had any issues with it.
When I had ignite installed, even though my SSID was the same as prior, I did have to re-connect the wemo device to my Wi-Fi. Going though the full connection steps. (Get in setup mode, connect to the device, set up the Wi-Fi there, etc)
