I just installed a new Asus dual band router. My two Wemo smart plugs were working find before the new router. Now they won't work at all. I've tried hard resets on the plugs with no luck. I've reinstalled the app with no luck. I've restarted the phone. I've tried doing it in airplane mode (which apparently worked for one user) with no luck. I'm absolutely using the 2.4 and not the 5g network. The router is right next to the plug so there is no signal issue. I can intermitently find the plug using wifi. I've been able to rename it multiple times. But ultimately, I can't get the app to find the plug to install. On one hand it seems like an app issue, but everything was fine until the new router was installed.
