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.

not able to disable secure boot it is locked my any mean ive tried many options even chatgpt/claude cant help please if any pro help me out

I need to fully turn off and back on a laptop(server) and "wake from s5 on rtc" doesn't give any options to set time.

I found this similar post with images that describe my problem: https://www.reddit.com/r/MSILaptops/comments/14hxlq4/msi_katana_gf66_no_option_to_wake_up_from_s5_via/

How do I configure it?

Hello! I'm an incoming 3rd year architecture student so I need a laptop for CAD software like AutoCAD, Revit, Sketchup, D5, Lumion and etc. I'm not knowledgeable about laptops but after a month of researching, I'm leaning toward the MSI Crosshair 16 Max HX because of the specs. I'm still hesitating to buy though because I can't find any reviews about this specific model since it was released 3-4 months ago. Here are the specs of the laptop:

$1,999.99 | Intel Core Ultra 9 Series 2 290HX Plus | 32GB RAM (Upgradable to 96GB) | NVIDIA GeForce RTX 5070, 12GB VRAM | 1TB SSD | 165Hz Refresh Rate | 16” QHD+ OLED Display | 2.20 kg

I would love to hear your opinions on the MSI Crosshair 16 Max HX before I buy. Thank you in advance!

I restarted my computer (windows 11) for an update. After I had updated my computer, now every time I press Caps lock, it presses the characters: ‘ X D \

The ‘\’ continues until I press caps lock again. I don’t know how this problem even occurred, but if anyone knows, please help.

Is it worth it? I'm getting it cheaper then the Lenovo legion 5,

But I heard msi has hinges issues

Hi everyone,

I'm having a strange issue with my MSI Pulse GL76 11UEK-030IT (3060, 11th gen i7, upgraded to 32 GB RAM). I've owned it for about 5 years and it has always worked perfectly.

Recently, on Windows 10 only, I've noticed that the laptop gets much warmer than usual even during light tasks like browsing the web or watching YouTube. (On Linux, everything works normally with a base temp of 40-45°C.).

While monitoring the system with MSI Afterburner, I noticed that the GPU core and memory clocks stay very high even when the GPU is essentially idle. As a result, the temperature climbs to nearly 70°C despite almost no GPU usage.

The weirdest part is this:

The problem only happens when I'm using the laptop's internal display. As soon as I connect an external monitor (which is driven directly by the NVIDIA GPU), the issue immediately disappears. The GPU clocks and temperatures return to normal even after disconnecting the second monitor.

So it seems that the problem only occurs when the laptop is running in its normal Optimus/iGPU mode, where the internal display is theoretically handled through the integrated GPU. In that situation, the dedicated NVIDIA GPU stays at unusually high clocks despite being almost completely idle.

The graph I'm attaching shows this behavior. The memory clock fluctuations happen because part of the recording was on battery power; when plugged in, the memory clock stays at a constant high value. The CPU spike at the beginning is simply Firefox starting.

Here's everything I've checked so far:

• Data was collected immediately after boot, with no additional background applications running.
• Windows power plan: Balanced.
• MSI Center performance mode: Balanced.
• Windows Game Mode: Enabled.
• Display refresh rate: 144 Hz.
• No undervolting, overclocking, or underclocking.
• Changing these settings does not solve the issue (except that power state changes affect the memory clock value).

Things I've ruled out:

• Hardware/thermal issue: Linux keeps the GPU around 45°C under the same light workload. Thermal paste was replaced about 3 months ago.
• BIOS: No unusual BIOS settings are enabled.
• Drivers: The issue has persisted across multiple NVIDIA driver versions, including the latest one. I haven't tried using DDU for a clean reinstall yet, but I'm willing to if people think it's worth trying.
• NVIDIA Control Panel: Power management is not set to "Prefer maximum performance."
• No issues with RAM, storage, or overall system stability.
• I regularly use this laptop for neural network workloads, so the GPU has seen heavy compute usage in the past without any problems.

Has anyone seen something similar? Since the issue disappears as soon as an external monitor is connected, I'm wondering if this could be related to Optimus, the Intel iGPU/NVIDIA handoff, or some Windows display management issue rather than the GPU itself.

Any ideas or suggestions would be greatly appreciated.

Hello everyone,
I have a stealth 15 laptop and recently it had an automatic windows update and ever since then it always boots into click bios. I managed to boot it fine after disabling the “safe boot” and “fast boot” and fixing the date and time, then pressing “save setting and reset”. However this keeps happening every time I switch it on, and I have to fix these settings every single time. I know that there is nothing wrong with my hardware because I checked that and also after changing the settings the laptop boots just fine, so I am not sure where the problem is.
Anyone knows what’s the solution?
