Section  - Installation
Auto Mode
If the switch on the back panel of the DAP-1522 is set to "Auto", the device will wait for 30 seconds, looking for a DHCP
server from the ethernet ports. If an IP address is assigned, it will automatically shift to AP mode. If an IP address is
not assigned from a DHCP server, the DAP-1522 will automatically shift to Bridge mode.
Create a Full MediaBand (5GHz wireless) Network
If you have two DAP-1522 devices and want to create a wireless network with full MediaBand technology you will need
to connect one Wireless Bridge to your router and move the switch on the back panel to "AP". The second Wireless
Bridge will need to be placed next to your Ethernet-enabled devices and you will need to move the switch on the back
panel to "Bridge".
