After three days since I pulled away the SSID from the 5Ghz radio and did reset the network options on TV, it seems to work good. I noticed that TV had memorized the network as a 5Ghz network and I guess that that's the reason why it tried to connect to the channel 40 on the 2.4Ghz network… maybe a bug of Samsung's…

Hi Nami, First of all, thank you for your answer. SSID Famiglia was already made for IoT devices and just configured as you said (v/k roaming disabled and 802.11 n/ax only disabled). The only thing I just changed now in my configuration is to remove this SSID from 5Ghz radio. I'll see what it will happen and then let you…

Hi after about 2 days, problem is still there...tonight and even some minutes ago there was down/up... at this point I believe that there is something in chipset design that doesn’t match my three switches. I also have a NWA1123 AC PRO that never showed this issue.

Hi, Yesterday I received replacement AP by RMA and now it seems to be ok. In 24 hrs no port up/down occurred and connection is 1000Mbps. Thank you to all of you and Zyxel support. Alessandro

Thank you Joslyn, I’ll wait for an answer from you.

Yes, I did. But the problem is still there... there isn't a cable issue, maybe hw or sw. Tried also to connect to a PoE switch instead of 12v plug but nothing changes. Thank you

Today I tried to connect NWA to another switch but the problem is still there... Randomly port0 goes down and then up after few seconds. So I can exclude switch issues.

Thank you Joslyn, I’ll try to add optional in switch then see the AP log. If nothing happens, I’ll send you diagnostics from NWA.

Thank you for your answer, it’s strange to me think at broadcasting because there are not so many devices connected to ap and vlan too. Netmask is 255.255.255.0 on all devices. Maybe I can try to activate broadcast storming prevent on the switch and see what happens.
