Wyze Lock Gateway setup not connecting to WiFi

Both Gateways just quit, tried both of my routers and “2” gateways will not connect. to my WiFi, waiting now for shipping labels to send both locks back. Worked for 2 weeks then nothing. Wyze support no help, 1 hour on phone with them. they can’t figure it out. Not happy. Pulling locks, back to old deadbolts! They’re scratching their heads.
