Updated the firmware to r605v2. And an annoying malfunction appeared. I have OC200v1, controllers, and 6 access points. The problem is this, ping chek is installed on my smartphone, periodically I ping computers and NAS on the local network. Now nothing is pinged from the smartphone (rarely 7-8 packets pass and disappear) Moreover, youtube, websites, and local resources (NAS and computers) are working fine. Only ping suffers, and from all smartphones on the network. At the same time, laptops (also wifi) ping goes fine. Computers by wire are also ok. There is no or interrupted ping only on smartphones. The firewall has removed all the jackdaws, has already changed all the settings. Nothing helps.
