Dot Gen 1 is saying Wemo Devices are not responding

[2369SecondAvenue]

I recently upgrade my network to the Netgear Orbi and reconnected all my WeMo devices.  I also have an Amazon Echo and two Dots in order to cover the entire house.  All of the WeMo devices are working perfectly with the Echo but the Dot I have in the bedroom is stating the devices are not responding.  I at first thought it was only the devices in the bedroom and have removed them from the WeMo setup and reinstalled them.  I have also reconnected the Dot to the network and also have completely factory reset the Dot and it still finds the devices not responding.  However 100% of the devices are working on the Echo.

Any ideas/clues

Thanks
