It looks like this for me:

> nmcli device
DEVICE          TYPE      STATE                   CONNECTION 
wlp2s0          wifi      connected               vghome     
p2p-dev-wlp2s0  wifi-p2p  disconnected            --         
...

Probably your Wi-Fi adapter/driver is missing the necessary feature.

After installing custom driver from github have additional options ‘p2p-dev-wlp1s0 wifi-p2p’

Try to switch SELinux to the permissive mode and temporarily stop firewall:

sudo setenforce 0
sudo systemctl stop firewalld.service

ND8801 · January 26, 2021, 5:00pm

No changes, tried with other miracast adapter too.
I think i need configure dnsmasq for p2p-dev-wlp1s0 wifi-p2p but i don’t know how do this. Can u help?
