I had an (immensely knowledgeable) associate who used to say that whenever he thought to himself that he really understood something, like maybe TCP/IP - something he was working with would behave in a way which made him realise he had not quite got there yet.
Not sure I really think I have mastered Unifi wifi, but I thought I was getting there.
At a relative’s house I have set up Unifi wifi. Two access points both 2.4GHz and 5GHz, hardwired back to ISP router. Local server running Unifi Network Controller v9.4.19.
I had been working with them to get all devices and clients onto a single SSID which made use of both APs and both frequencies.
There was a still a previous legacy SSID in place for 2.4 GHz only, for only one AP.
No clients connected to it.
So I thought this would be a good time to remove that legacy SSID - and so I “Paused” it (so being in a position to quickly re-enable in event of unforeseen problems).
Now two of the client devices have gone offline - even tho neither had used that legacy SSID fore more than a week.
Googling around I saw that making such a change does cause the controller to send new config info to the affected APs which could cause a momentary outage of signal. So maybe this is an artefact of “unrobust clients” rather than anything more substantial.
Any experience of glitchiness wrt the “Pause SSID” functionality?
Cheers.
