Hi there, about 6 months ago I upgraded my home (used as home-office) wifi network replaced my previous APs with a ZD1200 with 5 wired R720 AP's.
This revolutionised my family/business wifi experience, which had been unreliable for the previous 10 years trying all combinations of wired APs, possibly as I live in a built up area with a lot of interference from other wifi sources.
All was going well until a power cut 2 days ago - with rock steady wifi and my exterior IP cams never dropping out. Since the power cut, my wifi has been dropping in and out and I even get disconnected during internet chess.
I've tried everything I can think of, resetting and even powering on and off every single network component. I also checked the box directly under the self-healing Heading which said @Automatically adjust AP radio power....." (perhaps I should uncheck this as I have never checked it previously?).
Yesterday after powering on and powering off pretty much everything I seemed to have things back to normal, but alas today the network is "in and out" again.
So far all I have been able to do is to note that the issue exists in 2 AP zones out of the 5. I have many wifi clients including IP cams, iphones, ipads, amazon fire tv sticks. They work and then disconnect intermittently.
All I have changed on the zd is the self-healing setting and this issue definitely started after a power cut as my wifi has several family users every single day and we have quickly moved from perfect to almost unusable in two zones.
