Hi I have 6 of these, I have set up the first as master and updated firmware to latest. I add the second access point and it take 7-8 minutes and hooks up successfully and I can see in on the master web app and everything works good then when I add the 3rd it doesn’t work and makes 2nd one go in and out. I’ve tried resetting and starting over and different units same thing. Anyone know what is going on. Thanks
