Wireless Adapter TP-Link WN 823N (x86)

I installed Volumio 2.916 on an old Igel thinclient and it works great when it is connected via lan cable.
But the WLAN adapter is not shown. It is an TP Link WN823N.
lsusb shows it as
Bus 001 Device 002: ID 2357:0109

But there is no WiFi connection.

Cam someone help me?
