Hi everyone. I noticed that with preassoc_mac_addr=1 sometimes the randomized MAC address stays around, even though mac_addr=0 is set - it happens when reassociating to the same network as before. Please find attached a patch that ensures that the permanent MAC address is restored in this case. Best regards, Benjamin Richter
