[SOLVED] NIC not showing in ifconfig -a

I just turned on my laptop this morning, and found out that my wireless NIC is disappeared!
when I run

nmcli con up mynetwork

I get this

Error: Connection activation failed: No such suitable device found for this connection (device lo not available because device is strictly unmanaged).
ifconfig -a

shows me this

shows me this

I used to have 3 NICs and the wireless one was named wlo1 which is disappeared!
ps: I don't know how to get the nm manager version.

Re: [SOLVED] NIC not showing in ifconfig -a

Running meets installed kernel and the firmware package is installed.
But there's nothing resembling a Wifi chip (but a BT device on the USB)

=> Do you have a parallel windows installation?

Re: [SOLVED] NIC not showing in ifconfig -a

Does the device have a hardware switch for the wifi?

Re: [SOLVED] NIC not showing in ifconfig -a

Is there anything in dmesg about some pci device errors or so after a fresh boot? (Or journalctl -k)

That is a possibility. Or maybe the connection got somehow loose. You could try to open your laptop and reseat the wifi module.

it is possible that the physical connection has some interruption bcz now it came back and I can see it. I will mark this topic as solved.
