IS it true these can only be setup on a 192.168.1.0/24 subnet which is non configurable? Will it not pick up DHCP off a different type of subnet such as 10.0.1.0/24?
It has no built in DHCP client, so, no, it won't "pick up DHCP." They are static IPs only.
Set a static IP on your desktop/laptop to configure them if you have to. Though the default setting being a common router IP is a bit silly IMO.
