NetworkManager fails

Hello there,
Usually I use systemctl restart NetworkManager a lot because I cannot access network without doing it or rebooting. I am using HP Laptop Machine with AMD A6 and BCM43142 network controller with linux kernel and xfce4.
Here is the journal which I collected when the network suspended after minutes of booting
I have broadcom-wl-dkms, and bcm43142-firmware.
Thank you in advance.
