I purchased a new controller on eBay and had no real issues setting up the network with the default login and password. The system notified me that both my APS and the controller requireD firmware updates. The APs updated fine but once the controller update began the a login screen popped up that would not accept either the default login or my locally generated login and password. The system would also not reset. My box is now a brick. Out out frustration I purchased a second used controller and this time did not change the default login and ended up with the same result. I now own two bricks. Help!! I can’t believe no one performs firmware updates, what am I doing wrong?
