/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?

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.
