I've got some networking equipment (AP and 48 port POE switch) which I'm trying to set up at home but am not having much luck - I'm probably missing something obvious, see layout below:

I'm not getting power to the AP (don't have a POE injector, trying to use the Netgear to power but have it set to POE)
The switch is showing as connected on Ethernet through the eir modem backend but I'm not getting a IP assigned to it (when looking at DHCP leases)
It also works as a standard hub when I disconnect Wifi and connect direct to the switch through ethernet.
Netgear discovery tool not finding anything.
Any ideas?
