Wifi desapears when sleep mode

General Help
1

Hello, 3 weeks ago I moved from Windows 11 to Zorin 18 (I have dualboot). The problem is when i close the screen and I open it, the wifi completely desapears and I can´t enable it. I've tried a lot of different methods and nothing seems to work. I've read that some people changed the wifi card (MediaTek MT7921 to an Intel AX210) or changed the OS. But I really want to use Zorin OS, is there something else I could do?
My laptop is an ASUS Vivabook 16 and the wifi card is a MediaTek WI-Fi 6 MT7921.

Please post the terminal output of

sudo lshw -C network

here to show us which driver is used.

You could try the solutions mentioned here:

A script that is launched after suspend or the commands

sudo modprobe -r mt7921e && sudo modprobe mt7921e

(you can test if they work after suspend to activate the wlan. If yes, add them to autostart - create a launcher with these commands.

Or add the kernel parameter
mem_sleep_default=deep
to file
/etc/default/grub

Welcome to the Forum!

  • Are Secure Boot and Fast boot in BIOS disabled?
  • Is in Windows Fast Start-Up disabled?
  • Does Your System run in Wayland or X11?
  • Did You take a Look at the ''Additional Drivers'' Tab in Software & Updates if there is a Driver available for Your Wifi Card?
  • Is Your System completely up to date?
  • Can You post the Output of rfkill list in the Terminal?

I've tried the solutions in the forum but none of them worked.
When running the modprobe command manually, It shows this error:

The kernel parameter mem_sleep_default=deepshuts down my laptop.

Please add sudo to the command, the command was wrong. I changed it above.

Hello, secure boot, fast boot and fast start-up are disabled.

My system runs in X11.

In the "Additional Drivers" tab, there are only drivers for my nvidia graphic card.

Yes, my system is up to date.

Output of the rfkill list:

The terminal doesn't ask for password, It gives no output, and I can't type anything else.

I see here 2 Wifi Options. Do You have 2 Wifi Cards?

Nope, I only have one, which is the MediaTek MT7921.
