wifi conection doesn't properly works

[sorry for english errors]

I've installed arch recently. When was on arch image wifi and cabled conection works perfectly.
Now my cabled conection works very well. But on wi fi it some times just doesn't conect, as if the password was wrong.
As others posts suggest I've tried manually conect and get some errors. Looking at the logs of "systemctl status" command:

WPA association/authentication failed for interface 'wlp18s0b1'

I have wpa_supplicant dialog wireless_tools netctl instaled.

I use a Broadcom chip, looking at the wiki, they say that the its driver cames with the kernel, but it doesn't always works. In ubuntu I use a propietary driver on it, but even without, it works.
I don't know if I'd configured arch correct, but doing a reboot usally corrected this problem (and others doing a reboot is what started it).

make sure you have no conflicting services enabled

 systemctl list-unit-files | grep enabled

I am using same broadcom device, and occasional disconnections is known problem, as support for this device is not complete.

https://wireless.wiki.kernel.org/en/use … rted_chips

read note after the table showing supported chips

Please note: at least BCM4313 is not fully supported. Some models appears to work (users reported success), but some don't, and there's no indication that this is going to change. For example: http://marc.info/?t=138817851800006&r=1&w=2

I don't know for sure, but I think that is everything ok:

[wleles@archnote ~]$  systemctl list-unit-files | grep enabled 
autovt@.service                             enabled  
dbus-org.freedesktop.NetworkManager.service enabled  
dbus-org.freedesktop.nm-dispatcher.service  enabled  
dhcpcd.service                              enabled  
display-manager.service                     enabled  
gdm.service                                 enabled  
getty@.service                              enabled  
NetworkManager-dispatcher.service           enabled  
NetworkManager.service                      enabled  
systemd-timesyncd.service                   enabled  
remote-fs.target                            enabled

Maybe the problem is my wi fi modem, cause one of my friends came here today and stayed here for about 3h and couldn't connect, while me and other could.

Should I mark as resolved? I think that the only solution is patience.

You have both NetworkManager and dhcpcd enabled so that to me would be two services competing to control the network interface.
edit:
remove superfluous both
