not able to connect to wifi

I am able to detect wifi network using networkmanager,wifi-menu.but not able to connect.
dmesg says

[ 1193.319862] wlp4s0: authentication with 1c:7e:e5:f3:40:77 timed out 

Before i tried wps_cli .I got

Wpa_cli: could not connect to wpa_supplicant: (null) - re-trying .  

Tried netctl .That also did not help.

ip links give ouput

"3: wlp4s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DORMANT group default qlen 1000

Re: not able to connect to wifi

The wpa_cli error is most likely because you didn't run it as root.  All the other issues are most likely networking error that would turn on based on any search of the forums: multiple networking services running at the same time.

Disable all networking services, then try just one and report any errors.  I'd recommend starting with the simplest: wpa_supplicant and/or dhcpcd.

Re: not able to connect to wifi

I ran wpa_cli as root.

Re: not able to connect to wifi

In that case it's likely that wpa_supplicant isn't running and/or isn't configured to listen on the default control interface.

Re: not able to connect to wifi

You have to be joking, right?

Disable all networking services, then try just one...

So first you disable everything but wpa_supplicant, then you start and try to use NetworkManager.  Now you disable wpa_supplicant and try to use wpa_cli?!

In that case it's likely that wpa_supplicant isn't running and/or isn't configured to listen on the default control interface.

Pick one tool to use, then disable everything else, and use that one tool according to it's documentation.

You can't use NetoworkManager when wpa_supplicant is enabled.  You can't use wpa_cli when wpa_supplicant isn't running with the control interface specified in the wpa_supplicant.conf.

Re: not able to connect to wifi

disabled networkmanager and wpa_supplicant .
Then enabled network manager .

[root@piyush piyushbhatt]# systemctl start NetworkManager.service

Re: not able to connect to wifi

My apologies piyushbhatt, it seems I was a bit confused which may have made my responses a bit too critical.  Network Manager may pull in wpa_supplicant.service - it'd be good if a NetworkManager user could confirm this for us.  So there is every likelihood that you did exactly what I asked in the first place and I was misinterpretting the output.  Sorry.

That said, I'm am quite comfortable helping with wpa_supplicant (with or without wpa_cli) and dhcpcd, but I've never really used NetworkManager, so if multiple competing services aren't the issue, I'd not know the best approach to troubleshooting NM.

Re: not able to connect to wifi

Surely the troubleshooting is to test wpa_supplicant as standalone - without any additional network manager. More than capable of working alone, and would rule out other issues. Granted, configuration is a lot more manual, but it's more robust.

Re: not able to connect to wifi

I disabled all  networkManager.
created /etc/wpa_supplicant/example.conf with

ctrl_interface=/run/wpa_supplicant
update_config=1

As told in wpa supplicant wiki.

Start wpa_supplicant   with

wpa_supplicant -B -i interface -c /etc/wpa_supplicant/example.conf 

I was able to run wpa_cli .

[root@piyush wpa_supplicant]# wpa_supplicant -B -i wlp4s0 -c /etc/wpa_supplicant/example.conf

LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.

27 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.
