Device can't connect to main network but can to guest network?

My WeMo wall switch would not connect.  I tried the reset of the system, install and uninstall the wemo app, rebooted everything.  The time it worked I 1. clicked on the switch to not remember the wif info 2. clicked on "show password" so the password was no longer showing in the configuration window.  After doing those two changes it was able to connect to my orbi.  After connecting it updated and I reset the device and it connected the second time just fine.  I dont know if this was really what solved the problem, but since it did work for me I thought I'd share for others who may be experiencing Wemo to Orbi onnectivity issues.
