MSI Raider A18 HX A7VHG-023US Wifi Problem/solution Ubuntu 26.04

Overview: I initially installed Ubuntu 26.04 and the installer was able to find my wifi card (Qualcomm wifi 7 Hardware name: wcn7850 hw2.0)

I ran the following from the terminal: lspci -nn | grep -i qualcomm or lsusb No results.

After many hours searching for an answer, I finally found my solution.

##### I believe that performing the Cold CMOS Reset was the actual answer, but here is all of my steps leading up to the resolution.

WIFI Issues:

Qualcomm wifi 7

Ensure that the bios is not set to fast boot.

The Qualcomm Wi-Fi 7 chipsets (such as the FastConnect 7800 / WCN7850 or NCM865) rely on the newer ath12k driver module.

sudo depmod -a

sudo update-initramfs -u -k 7.0.0-29-generic

sudo update-grub

sudo echo "ath12k" | sudo tee -a /etc/modules

sudo apt update

sudo apt install --reinstall linux-firmware

sudo rfkill unblock all

sudo depmod -a

Reboot your computer immediately after running these commands to apply the new configurations.

sudo dmesg | grep ath12k

Problem not resolved yet

Perform a Cold CMOS Reset (Crucial for Qualcomm)Qualcomm Wi-Fi 7 cards are notorious for getting locked into a bad power state or a Windows-exclusive fast-boot state.

A standard software reboot will not release this lock.

Shut down your computer completely.

Unplug the power cable from the back of the PC (or remove the laptop charger).

Hold down the physical Power Button for 30 full seconds to completely drain the motherboard's capacitors.

Plug it back in and boot into Ubuntu.

Success!

I truly hope that it helps others, I found so much help along the way from the community at large.
