dragonlost Posted November 9, 2018 Share Posted November 9, 2018 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?
