[Solved]Wifi Issue

Hi I'm new with Arch and after have followed the guide for the installation i had wifi issue. Currently everything runs well, i have deepin as desktop enviroment, I-m using ethernet cable. If i try to connect my wifi... the system displays some errors... When i set the interface up it stays down..

 : ip link set wlp3s0 up
  :dmesg 

[ 1662.702501] pcieport 0000:00:1d.2: AER: Multiple Corrected error received: id=00ea

[ 1663.352042] IPv6: ADDRCONF(NETDEV_UP): wlp3s0: link is not ready

 

I can't figure out what is the problem..
I don't know if it can be usefull but i use Qualcomm Atheros QCA9377
And the driver is ath10k_pci

that is all, I'm here for each kind of question! Thank you

Re: [Solved]Wifi Issue

What's the output of

systemctl list-unit-files --state=enabled
systemctl list-units | grep -iE '(net|dhcp|wpa|conn|wicd)'

Also the dmesg is a rather meaningless excerpt, mostly indicating a wonky PCI bus (where it's not even clear whether the port somehow relates to your wifi)

Re: [Solved]Wifi Issue

Thank you for the replay

the first command shows:

UNIT FILE               STATE  
autovt@.service         enabled
display-manager.service enabled
getty@.service          enabled
lightdm.service         enabled
remote-fs.target        enabled

5 unit files listed.

the output of second is :

Re: [Solved]Wifi Issue

Stop dhcpcd.service, but either you screwed up the first command or your system is completely broken.

Re: [Solved]Wifi Issue

Again: if you attempt to do a manual WIFI connection, you need to stop the dhcpcd service first.
