What are your Wemo plugs' exact model numbers? How long have you been experiencing this issue? When the plugs gray out on the app, what're the LED behavior on the devices? To further isolate the situation, make sure that your Wemo devices are running on the latest firmware, and make sure the Wemo app tself is running on the latest version, too.

@Np1996 All noted. How far are your Wemo Switches from the router? Make sure that they have at least 2 - 3 wireless signal bars from the location where they're installed. Also, make sure that you have a stable internet connection.
Update this thread with more details so we can have this issue properly isolated.

Change your router’s Wi-Fi channel to avoid interference with other network devices in your area. This link can also be a good read in doing some workarounds: http://www.belkin.com/us/support-article?articleNum=44526
If those do not help, email us right away at WemoCares@wemo.com, and we'll have an Escalation Engineer contact you in this regard. Include the link to this post, and your contact number and location.

It's probably the extender blocking discovery. Reserving IPs for your wemos in your router's DHCP settings *might* help. If your extender has any settings for multicast be sure to enable it to allow them to flow to/from the router.
I doubt it's the channel but it is the support team's favorite excuse. That help page says "use auto" for the channel a few times yet here's support telling you to assign a fixed channel. I guess that link would be a good read for the support team too .
