Switch GS728TPPv2 not working when connected to wireless bridge

Hi all,

I tried others forums but to no avail ....

we need to switch our security cams to poe system. Since the building is not ours we cannot use utp everywhere.

Here is the basic setup of our Mesh network:

Main is GT-AX11000. We added 2 RT-AC67U and 1 RT-AC5300 in Mesh setup (so 3 nodes).
I want to connect a switch Netgear GS728TPP with utp on a mesh node (RT-ac67u) with 2 poe cams connected (node wireless connection to main router). I cannot reach them in this setup.

More relevant info:.

- RT ac67u has connection with the internet. I tested both wifi and UTP (with laptop). Main router UI confirms and reports all nodes online
- When the switch is connected (utp) to main router, cams are reachable and work as expected.

- When switch is connected (utp) to node that is connected (utp) to main router. all works (node is then just a utp switch basically)

So we think we must have missed sth basic in the setup or sth?

The switch is in still in default state. Nothing changed in settings.

I have been trying for weeks now, so maybe sbdy can point me in the reight direction?

thanks for taking the time!
