Unifi AP behind an extra switch: 2.4Ghz network stops working after ~30 minutes
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?
