/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?

    Measure the time after the reboot of the AP until the next failure.

    If it is always the same duration, then that excludes the memory problem. If it is a variable time, then that excludes the DHCP problem and probably also DNS.
