Wuze cam v3 , not saying ready to connect

Hi there i got nine wyze cam v3 and have been ove the months setting them up. Took one out today and after pressing the setup microswitch, wich i do feel. It does not say the ready to connect phrase, the other five i have activated did. Thank you.

First I would try using a pencil eraser to push the Setup button in. The button may be flakey. Second I would temporarily swap the power cord and power brick from a working camera to see if that could be the problem.
