Hi,
To start you need to factory reset both adapters,
plug them both into a wall socket next to each other, press the config/f reset button, hold in until ap light goes off, repeat on the other one.
Now you should have a red status light on both.
Press the config/f reset button on one for about 5 seconds, wait until ap light stays on, this one is now your access point (ap) that should be plugged in to your router when you have finished config.
Now press the ap adapter config button again for about 5 seconds until ap light flashes, then press the config button on the other adapter until ap light flashes, wait until they both stop flashing, wait a few seconds, the status light on both adapters should be green, and one adapter should have an amber ap light.
Hope this helps.
