hello.

 

I have a problem for quite some time on my tinkerboard.

I do not know if it's a software or hardware problem.
It appeared after connecting a special Raspberry USB Hub http://www.uugear.com/product/7-port-usb-hub-for-raspberry-pi/

I used this HUB on a raspberry 3b but he grilled the wifi chip (disappeared totally).
I thought I had to grill the wifi chip of the tinkerbard like the raspberry but I can see the chip turn on from time to time.

Today she has reappeared but "wlan0 not ready" in the network manager.
  

sudo ip link show wlan0
wlan0: <BROADCAST, MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000


  

sudo ip link set wlan0 up
RTNETLINK answers: Operation not permitted


how do you think I can activate it and how to know if the wifi acrte is well detect if it does not appear at all in the network manager?
