when i run:

systemctl stop NetworkManager.service
systemctl stop wpa_supplicant.service 

and then，run：

sudo miracle-wifid & 

It reports an error on the subject above. What is the reason for this?

Avoid attach image screenshots if posible.

Ser the wiki FAQ yo attach logs for support

The relevant info will be probably on journalctl

I have solved the problem, look at the journalctl log, in the /run/miracle/wifi/ path residual stuff, just delete it. Then the xxx wpa_supplicant or driver does not support P2P xxx problem occurs because the wpa_supplicant service restarts automatically. Resolved:

1. Stop Internet service first. systemctl stop NetworkManager.service systemctl stop wpa_supplicant.service

2. Ensure that all wpa_supplicant services are stopped. ps -ef | grep wpa_supplican[t] sudo kill -9 xxx
