Here's the whole setup, ready for initial configuration. * Note: Each AirStation may be part of 6 different bridges. Remember that each layer of bridges takes about half your total network speed, so avoid configuring daisy-chains more than 4 bridges long. A star-pattern is always better, with a central router serving multiple bridges. Configuring a WDS Bridge Once the AirStations are powered on, you will want to make sure that they are in factory default configuration. On the bottom of each, hold down the "INIT" button for three seconds. They will take 30-60 seconds to reboot afterwards. Power on your PC.
