3CX DLL-Sideloading attack: What you need to know

APX320s going offline

We are trialling Sophos APs for a wifi refresh but having some issues with them.

3 x APX320 - 2 managed through Sophos Central, one via an XGS6500.

They will occasionally go offline (red light, no ping response/LAN access but still advertising SSIDs and can still connect where network authentication isn't needed). Recently these have been going offline at roughly the same time. Cannot see anything on the switches. One is getting POE from the switch (Cisco 2960) and other 2 are into similar switches but powered by injector.

This is happening maybe every week, though it was much more regular some weeks back. Cannot access the cloud managed APs via console, but can get on to the firewall managed one.

Anything I can check? Can't see any logs on the AP and central/firewall doesn't seem to give me anything useful.

Power cycle required to get the back online then they work fine until next time.

  • Hello,

    Thanks for the information May I verify if your APX meets this power requirements

    APX320X - Maximum Power: 18.9W and the POE switch supports 802.3at?

    Also when the issue occurs what is the status of red light? Solid, flashing slowly or flashing fast?

    You can check logs in Central under Wireless>Diagnostics>Events

    For Syslog Wireless>Diagnostics>Syslog > enter syslog IP and Port

    Since this is also a trial, you may reach out to your local partner or Sophos SE to be able to assist you in a technical standpoint on your trial period.

    Many thanks for your time and patience and thank you for choosing Sophos
