There are 2 modes of operation:
- Access Point (AP) Allows wifi devices to use the DAP-1522 to connect to your wired network
- Bridge Allows wired devices to connect to your wifi network through the DAP-1522
There is a 3 position switch on the unit to switch between these modes (the third position is auto
which makes the decision between access point and bridge automatically based on if it can see a DHCP server.
With a pair of DAP-1522 (one as AP, one as bridge) it is possible to extend your wired network to (say) another building (in wireless range) without needing any wires between the 2. (And if you already have a wireless router, you'll only need 1 DAP-1522 running as a bridge).
I do not think it will acts as a wireless to wireless repeater (ie range extender).
