authentication failure

Can anyone help me what does “authentication failed” mean and how to fix it?

thanks in advance

Can you elaborate a bit on what you were doing when you received this message and where you are seeing it?

Basically, we are just deloading SMs for better traffic. Will this help?? another can you guys help me list down all registration alarm and what must do to fix it?? We have more that 11 000 APs and we need to act fast…


Is this in regard to PMP450 or PMP100?

I think we might be able to help you a bit faster if you contact Support directly and open a case.

Thanks for your help and I already did that but I wanted also to give their side based on their experiences. But anyway, thanks again.
