WeMo Connect Advanced - Not discovering device

Just wondering what someone might recommend for the following situation:

Changed out my internet gateway today and ever since one of my wemo switches isn’t working through the SmartThings app or with Alexa, but does work with the wemo app. I’ve checked the WeMo Connect (advanced) smartapp and tried the discovery function and it only finds another switch but not the switch in question.

Curious if I should try removing the switch in the SmartThings app, remove in WeMo app, etc.


Reinstalling in WeMo app worked.
