Hi!
We are always encountering sudden disconnection from time to time its just 1 or 2 or 3 out of 8 but there are times that all 8 APs are disconnected at the same time.
We have 8 EAP225 for the office, with average clients of 100. The Omada software is installed in a PC connected to a TP-Link TL-SG2428P (Network switch) which all APs are connected as well with POE. Our main router/gateway to the internet is a Peplink balance 380 router.

Already enabled internally the Omada ports listed here: https://www.tp-link.com/us/support/faq/3281/

What causes these disconnections and how can I resolve it?

Thanks,
