[SOLVED] Wifi scan without device?


for a script I want to scan for access points.

Usually I would call "iw dev wlan0 scan". But can be done when there is no wlan0 device configured?
Do I need to setup a temporary wifi configuration to be able to scan?

Or is there a more elegant solution?

  • thanks

iwinfo wlan0 scan

sure, but what if there is no wlan0 device?

As long as the hardware is there and the driver/ firmware present and loaded...

You can try something like iwinfo radio0 scan || iwinfo radio1 scan. This will either use an existing vif on radio0/radio1 for scanning or create one on demand if there is no suitable one yet.

thanks, that solves it.
