wifi issue

using arch linux, i had connected with wifi-menu after installation by installing wpa_supplicant and dialog.

had an issue with cinnamon, so i switched to xfce4. Noticed that the NetworkManager applet said that my wifi was disabled, even though i was connected using wifi-menu.

apparently the applet was there, but Network Manager was not installed. Long story short, i installed network manager and had issues connecting to my wifi(it would just spin), and if i tried to create one manually, i only had the option for WEP not WPA2.

if i try to go back to wifi-menu it says netctl-auto is controlling wlp1s0, tried enabling and disabling NetworkManager.service, did the same with dhcpcd.

if i look at journalctl i see that it connects, then deauthenticates "warn connection disconnected (reason -3).

Also this laptop (c720-3605) does not have a hardwire capability.

I've been searching this issue since last night, and i can't figure this out. can someone help me with this?

I'm not sure I can help you out with this but for those that might, please post the results of the following commands...

lspci -nnk | grep -i net -A2
Or, if this is a USB adapter...

lsusb -v
Also, try connecting to your network and when it fails, grab these results, as well...

Last but not least...

rfkill list
If you need to, you can copy the results onto a thumb drive and post them using another computer.

If you would like to check out other commands for additional information, please see here.

I can do that when I get home, but I think I fixed it.

I ran:

systemctl stop netctl-auto@wlp1s0.service
systemctl disable netctl-auto@wlps10.service

I am not sure what exactly was before .service, I'm not home to check my bash history. I think what happened was both netctl and network manager were running. Seems to be working now and I did a reboot and it automatically connected and seemed to stay connected.

hopefully when I get home tonight it reconnects from hibernation. either way I will post the output of those commands, as it might help someone with this problem if they do a forum search like I tried.
