Hi looking for a little advice, what exactly is 'Signal Quality' shown in the attached image (taken from Cisco controller)?
Is it the same as RSSI (dBm) or SNR? And what do the values on the image tell me about all three user's Wi-Fi connections? Is 0dB good/bad/ok? No idea.
Many thanks, much appreciated.

Thanks for that. So do you think that a 0 dB reading means that there is potentially a connection issue?
I ask because as many of us I am working from home without the ability to test these devices at their location. Thanks

OK so 0db means not connected. The device that was connected at 41db was also one of the 0db connections so I understand that. However the other 0db is a different device, why would there only be a single 0db 'non' connection for a device?
Does it just mean that the device has tried to connect or just hasn't started any data transmissions or something? Many thanks

Hi, I was paranoid about displaying to much info on the image and was hoping the 0db had an open and shut answer, wishful thinking!
OK thanks, it does sound like some sort of connection was attempted, perhaps with a different band and the device was not or no longer properly connecte.
OK many thanks for all you help and suggestions.
