My network consists mostly of Ubiquity components.  Recently all cameras connected to an edge switch went offline according to my video recorder page.  If I look at them through my Network page they are connected but they have no data throughput.  I can ping them and get a response.  

I tried to log in to the individual devices and it’s not liking my username and pw.  In the legacy unifi software/management page you could set all devices to the same username and pw.  What is that term and where is it in the new webpage?

Is it strange that I can ping the cameras but get no data/images from them?

Thanks
