I am trying to create an AP on a rpi3b. It worked once, and I don't understand why it does not anymore.

I am using a command like:

 lnxrouter --ap wlan0 myAP -p thepassphrase -w 2 -c 8 --country FR --isolate-clients --random-mac  --no-virt

lnxrouter stops after settings the random mac.

I can test the same command on another rpi3b (+), and this works fine.

I have uninstalled haveged, because it was not installed on the one where it works, but that makes no difference.

I have no clue what is wrong. I wokrs with create_ap
