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