/edit: did a firmware upgrade of the AP and can’t replicate it anymore. Thanks all for the input, much appreciated. In case it happens again I will use your tips.

I have a very weird issue. I’ve got a relatively simple network setup:

  • router connected to ONT (Fibre)
  • 10 port switch A connected to router, cables to various places in house
  • 4 port switch B connected to switch A, with TV & Xbox connected
  • Unify WiFi AP connected to switch A, both 2.4Ghz and 5Ghz networks

That works well. However, when I connect the WiFi AP to switch B I’m having issues. Initially it all works well, but after ~30 minutes the wifi stops working; I can no longer ping e.g. the router. It only happens to one of the WiFi networks (2.4Ghz or 5Ghz), not both. A reboot of the AP solves it again, but then it stops working after ~30 minutes.

Both switch A and B are 1Ghz switches, zero issues with other devices.

Any idea what I can try?

    I had a similar issue and it related to the uplink connectivity monitor. Unifi monitors the gateway and controller IP and withdraws the SSID if it can’t contact either of them. Make sure you have turned off wireless meshing on the device and I think you can manually disable the uplink connectivity monitor.

    Do you have a continuously running unifi controller or is it only running when you do the config? Does it do the same thing with the controller opposite to how it is now (ie if you aren’t running it does it do it when you leave the controller on)?

    Are you running the 2.4 and 5 as separate SSIDs or the same one?

    Are you on the latest controller and firmware?

    Double check the AP doesn’t have a DHCP server enabled. Also, check routes and IP settings when a client first connects to the AP and things work, then again when things stop working.

      Yep, thanks for checking, there’s only 1 DHCP server on my network. I’ve just moved it back to behind switch B and will do more investigation when the problem occurs again.
