Putting a secondary adapter into monitor mode using the network manager

How did you get multiple wifi dongles to show up. I have a ralink and realtek. Both show up when using lsusb but only Ralink gets assigned to wlan0. But seems like my realtek doesn’t get assigned anything

Check dmesg for messages about drivers. I had that happen with several adapters that didn’t have driver support baked into balena os. Look for USB messages with dmesg | grep usb or just read the whole thing and google things you don’t understand.

Despite some effort on my part, I have yet to get any of them working. So unless there are prebuild drivers as a package for debain then you might be out of luck. Even if there are, you still might be out of luck. I really had a hard time with drivers.

@tacLog that was it I switched out a wifi dongle and it started working Ralink is no good. Now I have two realtek. I’m looking to flip one into monitor mode now. I’ll try your method.

Good luck!

I always used:
iwconfig
to check if I succeeded during my early tests.
