After a fresh install of Gnome, Network Manager not worked.(SOLVED)

When install arch linux, I add following package:

pacstrap /mnt networkmanager iw wpa_supplicant dialog network-manager-applet wireless_tools net-tools

wpa_applicant + dhcpcd is worked when disable NetworkManager, But when start this service.

wpa_applicant is start failed with:

p2p-dev-wlp62s0: Failed to iniialize driver interface.
P2P: Failed to enable P2P Device interface
...

When i try to connection wifi use NetworkMangger, following is step:

Select Network =>  Select correct SSID => Click connection.

Nothing happen as expect (No tips about input password etc...)

When i run  "systemctl list-unit-files --type=service |grep enabled", got:;

autovt@.ervice
dbus-org.freedesktop.NetworkManger.service 
dbus-org.freedesktop.nm-dispatcher.service 
display-manager.srvice
gdm.service
getty@.service
NetworkManager-dispatcher.service
NetwokManager-wait-online.service
NetworkManager.service
systemd-fsck-boot.service

Thanks

Thanks for reply, I tried with nmcli, it worked.

In fact, following case all worked.

1. nmcli dev wifi connect MYSSID password MYPASSWORD worked!
2. Wifi-Settings -> Visible Networks -> select SSID  worked!
3. if connect successful use any previous way, reconnection with "Select Network" is worked!

But, if use

Select Networks => Select a new SSID => click connection button, no password dialog is poped,
no any response, so wired ...

Thank you very much, I resolved this issue now, it caused by my same one external monitor use two video port
connect to my laptop (one VGA, one  Thunderbolt), And gnome consider my laptop have three monior is connected.

this cause poped dialog can not be see when select a SSID, after remove one line, it worked now.
