After sleep, Wi-Fi detects signals, but impossible to connect

IMPORTANT EDIT: It feels that it's been fixed now.

Update your Manjaro system and see if it works.

I have been having this issue for a while, I think it was OK some time ago, and after some update it started happening.

Sometimes, when I shut off Wi-Fi through KDE Plasma's toggle before suspending, after waking it up I could toggle it back up fine. But sometimes it does not work. And it's annoying because I have to restart the computer to get Wi-Fi back.

What happens is that, it is detecting networks perfectly, but when it tries to connect, it just stays there... trying to connect, and after like a minute it shows something like "credentials failed".

I am worried it might be due to some error with the kdewallet thingie, but I am not sure, it might as well be an issue related to correctly shutting off and on the network service.

These are my Wi-Fi specs. I am running stantard Manjaro KDE.

  •     Subsystem: Lenovo RTL8821CE 802.11ac PCIe Wireless Network Adapter
  •     Kernel driver in use: rtl8821ce
  •     Kernel modules: 8821ce

On a side note, do you know of any command to try and restart the network service, so I can try and not restart the whole computer?

Here is a suspend service I wrote:

If you substitute your network particulars in the service it should work for you. The network restart commands are included in the service.
