You can definitely use non-UniFi switches -- I do -- but unmanaged switches won't reliably carry VLANs, which means you can't make a VLAN-isolated guest SSID or IoT-only SSID. So you might wanna upgrade that switch later, but it's not something you have to have on day one.Did think of one more question for the evening; are there any issues plugging the AP's into a switch that is plugged into the Cloud Gateway Max. It would be unmanaged netgear switch.
