[Solved]Wifi Random disconnects and i'm not able to bring it up after.

Hello guys, I'm using a company laptop and I installed Arch linux + i3-gaps.
I'm using NetworkManager as my network manager.
I can connect to the wifi interface smoothly, but it random disconnects after a while and I can't bring the interface back up.
Even running `sudo ip link set <interface> up`returns an input/output error.

The driver is ath10k_pci.

Can you guys help me? (I didn't post any outcomes because I'm not sure what to post, please feel free to ask me for more information.

Please paste the output of:

systemctl list-unit-files --state=enabled

Moving to NC...

If it's another issue I'm thinking of, posting a

dmesg

might be helpful as well.

```
$ systemctl list-unit-files --state=enabled
UNIT FILE                                   STATE 
autovt@.service                             enabled
bluetooth.service                           enabled
dbus-fi.w1.wpa_supplicant1.service          enabled
dbus-org.bluez.service                      enabled
dbus-org.freedesktop.NetworkManager.service enabled
dbus-org.freedesktop.nm-dispatcher.service  enabled
display-manager.service                     enabled
getty@.service                              enabled
lightdm.service                             enabled
NetworkManager-dispatcher.service           enabled
NetworkManager.service                      enabled
ntpd.service                                enabled
wpa_supplicant.service                      enabled
remote-fs.target                            enabled

14 unit files listed.
```

I'll post dmesg as soon as the wifi goes down again!

PS. How do I tag code? ><

Disable the wpa_supplicant.service, you should not have conflicting network management utilities running at the same time.

Look at the bbcode link under every post editor for information on how to use certain tags.

V1del, I've done that and network manager stopped working. When getting wpa_supplicant back up it started to work again. Doesn't NetworkManager use wpa_supplicant???

You''ve done what exactly?
NM invokes wpa_supplicant, but you should not have wpa_supplicant services *enabled* next to NM.

I've disabled wpa_supplicant and the wifi became unavailable

Edit: Nvm, tried it again and now it seems to work after restarting the PC again. For now it's solved. I'll just wait for a few hours to see if that fixed the issue and If it did, I'll mark the post as solved! Thanks guys!
