I have deployed 40,50 AX1800 at several motels. For no apparent reason, at least 5 have just stopped working. I have tried to trouble shoot, but nothing works. Each AP is broadcasting the SSID as Zyxel mesh. Every AP was on Nebula and working fine.

This will be a huge issue for me if this continues. I will need to replace at my expense.

What is happening? Is there a fix? Or should I look for another manufacturer?

    Not sure if Nebula has like a limit but I doubt it maybe you got unlikely and some have failed out right?

    Are you able to release it from Nebula and test as stand-alone when reset?

    I released all of the APs that stopped working. I try as stand alone, but no go. The SSID is present also. So I tried to log in through WiFi, but My laptop won't connect

    Hi @RonLipp1957 ,

    The symptom looks like there is SSID(s), but the clients can't connect to the SSID. We have some recommendation below.

    1. Fine-tune the deployment of AP's location. Your laptop/ client's connection signal recommended –70dBm or above.


    2. Fine-tune the wireless environment by

    • Adjusting your 2.4GHz radio power to 5dBm
      lower than your 5GHz radio
    • Adjusting the channel width to 20MHz for each radio to
      reduce co-channel interference.
    • Enabling DCS and disabling Avoid 5G DFS channel to have the best channel.

    3. Forget or delete the SSID profile on the client then reconnect again.

    In case after changing the configuration, the issue still recurs, please provide the AP's diagnostic file, client MAC address and connected time. We'll check and tell you if there is any update.
    The path: Maintenance > Diagnostics > Diagnostics
