Wifi Not working

[HeXiT78]

Hi everyone,

I’ve been struggling with an issue on my system and could really use some help!

I'm having trouble activating the WiFi and for Bluetooth, I can find all the devices around me, but when I connect to them, I can't interact with them. My Bluetooth mouse (M535) doesn't move the pointer, and my Bluetooth headset remains silent.
I have disabled FastBoot and SecureBoot in the BIOS.
I believe the driver for the M.2 Intel AC 9260 should be iwlwifi, but it doesn’t load at all.
I've tried reloading the driver without success.

$sudo modprobe -r iwlwifi && sudo modprobe iwlwifi

$ dmesg| grep iwl
[ 4918.196057] iwlwifi 0000:01:00.0: Unable to change power state from D3cold to D0, device inaccessible
[ 4918.196164] iwlwifi 0000:01:00.0: Unable to change power state from D3cold to D0, device inaccessible
[ 4918.196626] iwlwifi 0000:01:00.0: HW_REV=0xFFFFFFFF, PCI issues?
[ 4918.196674] iwlwifi: probe of 0000:01:00.0 failed with error -5

I’m running a Ubuntu 24.04 base and i have tried Fedora, Linux Mint, and Pop! OS with the same results.

Both WiFi and Bluetooth are not functioning correctly. I believe the issue might be related to ACPI D3Cold Support, which I need to disable in the BIOS, but I couldn’t find these option or another way to deactivate this?

I went into the advanced BIOS settings, but unfortunately, there weren't many additional options to explore.

I need a solution for the problem I’m facing.

Thanks in advance for your support!

Hi,

After some research and attempts, the only solution I’ve found so far is using the noacpi option at GRUB boot.

This enables the WiFi, but unfortunately, the integrated keyboard and all ACPI-related functions stop working.

Is there a technician or someone familiar with HP laptop BIOS/ACPI who could help me resolve this issue?

Hi,

I’m still seeking support from the tech community. Did I perhaps post in the wrong section? I’ve noticed other posts receiving responses, but mine hasn’t.

Hi @HeXiT78,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

It looks like you're dealing with a complex issue involving both WiFi and Bluetooth on your HP 15 laptop running various Linux distributions. Based on the information you provided, here are some steps and considerations to help resolve the problem.

ACPI and Power Management

It sounds like the ACPI (Advanced Configuration and Power Interface) is affecting your device's ability to properly initialize the WiFi and Bluetooth hardware. You mentioned trying the noacpi option, which indicates that ACPI might be the culprit.

Disabling ACPI D3Cold Support: Unfortunately, not all BIOS/UEFI settings allow disabling ACPI D3Cold Support directly. Since you didn’t find an explicit option in your BIOS, you might need to look for more general ACPI-related options or settings like "Power Management" or "Advanced Power Management" in the BIOS.

Try Different ACPI Options: Since noacpi causes keyboard issues, you might try other ACPI options in GRUB. For instance:

• acpi=off (disables ACPI entirely, which can cause various system instability issues)
• acpi=strict or acpi=noirq (disables ACPI IRQ handling, which might help with specific issues)

1. Open a terminal and type: sudo nano /etc/default/grub
2. Find the line that starts with GRUB_CMDLINE_LINUX_DEFAULT and add the desired option, e.g., GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=off"
3. Save the file and update GRUB: sudo update-grub
4. Reboot the system.

WiFi and Bluetooth Drivers

Since you mentioned that the iwlwifi driver fails to load and you’re experiencing issues with both WiFi and Bluetooth, ensure the following:

Update System and Drivers: Ensure your Linux kernel and firmware are up-to-date. Sometimes, issues are resolved in newer kernel versions or with updated firmware. You can update the system with:

• sudo apt update 
• sudo apt upgrade

Check for Missing Firmware: Ensure the necessary firmware files for iwlwifi are installed. For Intel WiFi cards, firmware files are often provided by the linux-firmware package:

• sudo apt install linux-firmware

Blacklist Conflicting Modules: Sometimes, other drivers or modules can conflict with iwlwifi. Try blacklisting unnecessary modules:

1. Open the blacklist file: sudo nano /etc/modprobe.d/blacklist.conf
2. Add lines to blacklist conflicting modules (if known).
3. Save the file and reboot.

Note:

Check Logs: Review system logs for additional error messages related to WiFi and Bluetooth:

• dmesg | grep -i bluetooth 
• dmesg | grep -i wifi

Test with Live USB: If possible, test your system with a live USB of a different Linux distribution to see if the problem persists. This can help determine if the issue is related to your current setup or a hardware compatibility problem.

BIOS Update: Check if there’s a BIOS update available for your laptop model that might address hardware compatibility issues. Sometimes, updating the BIOS can resolve ACPI-related problems.

If you’re still having trouble after trying these steps, the issue might be specific to your hardware or the Linux kernel version you’re using.

I hope this helps.

Take care and have a good day.

Hi, thank you for your support, it's greatly appreciated.

For Bluetooth, I’ve noticed better support when using KDE rather than a GNOME-based system. I can even use my Bluetooth mouse!

But for now, I’m focusing on the WiFi issue.

I’ve tried several combinations, as you suggested, to disable ACPI and/or ASPM. After many attempts and experiments, I’ve had no success. I even compiled the kernel with minimal ACPI modules, but it’s consistent, if ACPI is even slightly enabled, the delay in resuming the WiFi card causes a timeout, leaving it stuck in D3cold.

I’m becoming convinced that the only workaround for this issue might involve a setting that doesn’t exist in the BIOS. But before I'm fully convinced, I’m testing other distributions, even though I’m less familiar with them.

If there were a way to unlock more options in the BIOS, my chances would definitely improve!

I will continue my search, thank you again for your support!

Hello,

Unfortunately, I wasn't able to resolve the issue. I also tried with another M.2 RTL8852BE card, but the same problem occurs after the system resumes from sleep. For now, I will simply blacklist the driver and wait for future BIOS and kernel updates.

Meanwhile, I buy a USB BrosTrend AX300 Nano WIFI 6 Linux Compatible adaptor on Amazon for around 25$, and it works flawless!

Thank you.
