Network connnecting issue. Need to restart several times to connect.

I need to restart my system several times to connect to internet. I am using Network Manager. It cant establish a connection without restarting.
When I cannot connect to the internet my system gives these outputs.

[indra@life-hack ~]$ sudo ip link set wlp2s0 up
