Hello to everybody, this is my first message on this forum.
I own a Zyxel NWA1123-ACV2 from some months, configured as standalone AP, connected to a Netgear GS108E-v3 switch.
I noticed from several days that uplink port sometimes goes down and then up after few seconds. Sometimes it happens every hour, or every 20 minutes, or few times a day. When it happens, front LED flashes red.
Obviously, devices connected in Wi-Fi loss internet connection (e.g. VoIP, streaming, online gaming, and so on).
I installed last firmware versione (5.35) and upgraded also Netgear switch's firmware, tried to disable DCS, radio2, tried to change ethernet cable but problem doesn't disappear.

Can you suggest me something to do?

Thank you
Alessandro

  • Maybe its Broadcasting to heavy, something i see on our Dualband APs too.
    check subnet mask of all members, use the highest bit mask thats possible for all at the network connected devices and ap. That should help to get some days of uptime instead of minutes or hours.
    unfortunately it want solve the problem throughout.
  • 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.

    Hi @alextouch

    Please help to collect diagnostic on NWA1123AC-v2 if adding the option on switch does not help.
    Thanks.

    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.
  • 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.

    Sorry if the idea is silly: Did you change the ethernet cable when you tried to connect to another switch?
  • 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

    If your device is covered under warranty, and you have a copy of your proof of purchase invoice.
    I would try to get a replacement hardware.

    Hi,

    We received the diagnostic, and it is under analyze now.
    If there is any conclusion, I will reply to you via the private message.
    Thanks.
