Hi gurditta123

For wifi issue:
Could you try upstream linux-firmware and kernel one by one:
linux-firmware:
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/
Copy all the iwlwifi-QuZ-a0-jf-b0-77.ucode to /lib/firmware, or cope all iwlwifi-* to /lib/firmware.

Then check if it's fixed.

For i915 issue:

Please try to append the following kernel command line in grub.
intel_idle.max_cstate=1 i915.enable_dc=0

to check if it works.

Another clue is the BIOS ACPI show EC method to GPU is configured wrongly.
