/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 can imagine several causes:
-
more than one DHCP server in your network (most likely)
-
very wrong DNS setup in your network (unlikely, because I guess you would have given us a hint in that direction)
-
heavy downloading traffic and one cheap plastic device (router, switch etc.) runs out of memory
There’s only a single DHCP server, a Pihole, which also serves as DNS. Switch B is a cheaper switch, so that may be the culprit. I use it for heavy downloading from my Xbox and that is never a big issue. Speeds fluctuate from 100 to 900mbps (my max) but that’s not necessarily a switch problem.
