Hi all,
Today i booted with my external drive into my linux, i noticed my wifi icon / wifi connection was completely gone. I checked in settings as well, the entire wifi setting was gone. Is there a terminal command to enable wifi whenever happens this again ? because i think wifi did not get started somehow.
I rebooted the machine and booted into the same drive and wifi is back again.

Does your fn+F12 do the wifi switch?
Try:
sudo modprobe -r ath10k_pci ath10k_core
sudo modprobe ath10k_pci
sudo modprobe ath10k_core
Nope fn + f12 is scroll lock, fn + f3 does toggle between airplane and wifi.
What does those commands do ? remove the driver and reinstall ?
Those commands instruct the Module Prober to remove the existing configuration, then to replace them with the Module for your device driver.
I do not know if it will work... But it is harmless to try...
Will try it out when i happens again, thanks.
Hold on... Is this an intermittent problem? Wifi is currently working?
Yes it's working after i rebooted. First boot today the wifi was completely gone. Wifi in setting option was gone too, like the card was dead for a moment.
Maybe a reboot was all you really needed. Please keep this thread posted if it repeats...
That's why i asked if there was a command to enable it somehow. Never had this issue since i started with linux back in augustus.
Used to be (replace parentheses with your network interface)
sudo iwconfig (wlan0) up
Not sure if it has changed. Can test with using down, then up.
Thanks again, i saved it in my linux tutorials. If it ever happens again i will test it.
@Michel
Don't you think
"WiFi did not initiate at startup"
if a better title?
I think WiFi module does not boot but initiate.
How can that happen ? i have this laptop for 4 years and never had this before.
Sometime reboot is required after a certain update.
(Do not ask me which update - but it happened to me more than once).
@Aravisian might have some idea.
Well i cant recall i installed any updates yesterday before i booted up today.
@Aravisian, today it happens again. I tried your command and it does not work.
Rebooted the machine and it's working again.
Maybe Zorin doesn't come with iwupdown...
Right. Networkd (sigh) Swarf's gonna kill me...
sudo ip link set wlp2so down
sudo ip link set wlp2so up
I will write these down if it happens again. Wonder why it happend today after 25 days
