As somebody commented in this thread, removing and adding kernel modules solves the problem until next reboot:

sudo modprobe -r iwlmvm iwlwifi
sudo modprobe iwlmvm iwlwifi

Bluetooth is unaffected.

I started having this problem already on Fedora 41 with kernel 6.11.*. I found some threads where people had similar problems. According to those threads, it has already been resolved. However for me problems haven’t disappeared since then.

Possible similar threads:

Edit

The problem happens only when sleep is in “Suspend-to-RAM” state. When i set suspend to be “s2idle” by booting with kernel parameter “mem_sleep_default=s2idle”, Wi-Fi work fine.

LHWDB probes model. There were similar models with Reaktek WiFi, but only found this one with Intel AX200. WiFi is often configured so it can enabled at boot (with minimal firmware to allow IT to update the systems in a cubicle farm at night), so your WiFi may be initialized using firmware from UEFI/BIOS. Power management may also be a factor. It is worth making the effort to see if WiFi can be disabled in UEFI/BIOS ans also try different power management options (is any) so it is forced to start with the Linux firmware, but with few similar models running Linux there may not be anyone with the expertise and access to the hardware who could sort out the problem.
