But you can power only 1AP right? I bought a cloudkey and Unifi switch 8-60W but the switch can’t power up the cloudkey which is weird. Then after using a POE injector the cloudkey starts working…
Do you have the cloudkey plugged into the correct port, ports 5-8, and is poe enabled? That switch can do 802.3af which the cloudkey, new and old, run off. You should be able to power 4 802.3af devices off that switch without any problems.
I prefer a wired router.
QoS does not help with bufferbloat. It helps to get some traffic before the rest, but you will have the buffer full with all the other traffic.
If you have PFSENSE or similar firewall use CODELQ traffic shaper instead. If you want use QoS, but I find QoS unnecessary.
