Error in setting wlan0 down/up

Hi all,
I’m running Ubuntu 20.04.1 LTS server on Vim3 pro, and whenever I try to do simply:

sudo ip link set wlan0 down
sudo ip link set wlan0 up

The kernel spazzes out and I have to hard reset the machine. Any ideas on how to combat this?


Hello @conor

Which image you used to test?

@conor Hello , I had test it yestarday . It printed some error info . This print information does not affect the use.

Can you provide complete print info ?
