Hello sg0106,

you have the problem, that your wifi card isn't shown in your terminal output. Do you really have the same card in your laptop as in the linked thread? I found here the data of your laptop model with another Realtek card:

https://linux-hardware.org/index.php?probe=6b5c0afc1f

So it could be, that you have that card: RTL8821AE 802.11ac PCIe Wireless Network Adapter

Can you show the terminal output of:

Code: Select all

Check UEFI/BIOS settings and see if WLAN is enabled
