I operate a dense Unifi network at a school with 56 access points (AP-AC Pro and nano HD) behind an UDM Pro and 17 Unifi switches. Each room is equipped with an AP, so that in principle an AP does not have to supply more than 5-7 meters in a radius “alone”.
About half a year ago the WIFI was consolidated - before we only had about half of the access points. Only every 2nd room was supplied with an AP.
Since the upgrade, I’ve noticed that wireless devices have a good WiFi signal, but no website is reachable (DHCP?). But push notifications do arrive …??
A short deactivation and reactivation of the WIFI on the device solves the problem.
I have already tried a lot of settings on the controller and also tested various firmware updates. Unfortunately, this problem remains unsolved. So far, we have not changed anything in the wireless settings of any individual AP. The standard values are set here.
However, after the densification, we initialized the RF scans on 2G and 5G and initiated the automatic adjustment of the channels.
Maybe you have a suggestion?!
Thanks and greetings from Germany (and sorry for bad english)
