Hi,

I have three NWA110AX WLAN Access points in our office - one is connected via ethernet to a DSL router - the others via wireless mesh.

In the course of a day it happens several times that one of the access point looses connection. I do not see anything in the logs, what helps me. Beside this message:

"System Nebula connection failed."

It does happen more often over the daytime, when clients are active.

See:


The radio settings are:





Any idea what to change / where to look?

    Hi @LeifHack

     

    Is the AP a repeater that often disconnects?

    Mesh connection quality will be greatly affected by signal strength, deployment space and interference. When repeater loses uplink from root, the AP goes offline.

    The best practice to place APs is face to face direction with less obstacles especially metal and signal must be better than -65dBm.

     

    Would you share the deployment scenario with us by graph or taking photo?

    After all physical conditions are good enough for mesh, if the connection still failed we can help to check if any logs tell the hint.

     

    Thank you

     

    Regards,

    Bella

    Hi,

    thank you for your feedback.

    It is the AP with direct wired ethernet connection (1 GB/s) to the gateway that goes offline... And in the night the APs have very little connections problems, so it seems to be the case, that the problems occur mostly when clients are involved. This graph is the one with direct wired ethernet connection to the gateway.

    This is our topography:

    Hi @LeifHack

     

    Most often root cause of the case is the conflict IP in the topology to cause AP’s traffic dropped before goes out the gateway.

    If the problem still happens after confirmed above condition exists in your network or not during the day, please enable the Zyxel support at Help > Support request > Invite Zyxel support as administrator, save the changes and provide the Org and Site name for us to check, thank you.

     

    Regards,
