command failed: Device or resource busy (-16)

[KArim1]

When an access point turns on and off repeatedly, AC7265 does not detect any access points including the one has been connected before.

I tried to scan with iw command (# iw wlp2s0 scan), but it shows "command failed: Device or resource busy (-16)" and cannot get an AP list.

1. Do you know in what conditions this failed message shows?

2. Is there any other commands as a workaround?
