WiFi Network not connecting

theta · 2016-09-30 11:25:31

I have been trying to connect to a network named dlink at a Public Place with wpa security enabled

[user@pc ~]$ netctl start dlink-kaha
==== AUTHENTICATING FOR org.freedesktop.systemd1.manage-units ===
Authentication is required to start 'netctl@dlink\x2dkaha.service'.

==== AUTHENTICATION COMPLETE ===
Job for netctl@dlink\x2dkaha.service failed because the control process exited with error code.
See "systemctl status "netctl@dlink\\x2dkaha.service"" and "journalctl -xe" for details.
[user@pc ~]$

This is what most commonly happens! The network doesn't connect. Once in the past 5 days I have been able to connect to the network after resetting the router.

This is what happened in on of the lucky dmesg outputs. Normally dmesg doesn't show anything after the line - "IPv6: ADDRCONF(NETDEV_UP): wlp5s0: link is not ready"

Linux boolean-pc 4.4.21-1-lts #1 SMP Thu Sep 15 20:38:36 CEST 2016 x86_64 GNU/Linux

I normally use wifi-menu to connect to wifi networks, but just to debug I was now using netctl and some manual tools.

PS: At the same time, my andoird Moto G3 can easily connect to this network. And if I create a hotspot then I can connect my machine to it. So I came to the conclusion that there is some compatibility issue between my machine and this router. Just an intelligent guess though.
