wlan device not found

[wahaha 4]

I reinstalled debian onto the tinkeboard 2s, and added the below to /etc/network/interfaces

# Add the following (for ethernet):
auto lo eth0
allow-hotplug eth0
iface lo inet loopback
iface eth0 inet dhcp

 

However, when I did:

ifconfig

It produced the below result:
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500

As you can see, wlan / wlp1s0 is not found in there. As such, I am unable to connect via wifi / bluetooth.

 

Is there a driver / kernel / firmware that I can use to update the drivers so that the wifi and bluetooth modules are detectable?
