WAC540 connected to unmanaged switch connected to Sky Q Hub/Router
Hi,
I have this setup:
Sky Q Hub (with all WiFi features turned off)
TP-Link Unmanaged 8 port switch with 4 ports PoE+ (ports 1-4)
My non-PoE devices connected to ports 5-8 on the TP-Link, including the uplink to the Sky Q Hub
a NETGEAR WAC540 connected to port 1 on the TP-Link, getting power via PoE+
The WAC540, when connected, is causing the Sky Q Hub to block the TP-Link switch completely causing complete loss of internet. Local to local device access is fine. When I unplug the WAC540, everything comes back to life on the Sky Q Hub/Router.
Has anyone experienced something similar? It screams like an STP issue, but I'm not sure what the WAC540 is doing to cause the Sky Q Hub/Router to shutdown its ethernet ports.
I'm on the very latest firmware now, however it's been happening since install 2 days ago at which point it was on a previous firmware.

PS: I have 2 WAC540 actually, with the 2nd one connected via WDS Bridge on the 5GHz High band to connect 2 building. The 2nd one does not have a direct cabled connection to the switch where the first one is.
What tp-link poe switch is it?
what happens if you power the WAC540 of a power supply and not from poe?It's the TP-SG1008P v4 (which has PoE+). Haven't tried power supply as the WAC540 doesn't come with one and didn't think it would be necessary.
Was think of it for just testing. It wouldn't be the first POE switch that wasn't supplying full power.
Also make sure to have the poe suppying port 1 on the WAC.
The power supply is a 12VDC 2.5A power supply. You might have one sitting around from an old router (or even current one) for testing.
