Problem with my TL-WN822N (Wifi adaptater)

Hi,

I have a problem with my USB Wifi Adapter (TP-Link TL-WN822N) or with his driver. At the beginning of the Post-Installation ,when I turn on my raspberry pi ,there isn't the SSID “PirateBox: Share freely” (my WIFI adapter is connected but the indicator light does not light and my ethernet cable is is disconnected).

Can you help me please ?

Thanks
