Wi-Fi connection drops when joining any voice chat with Bluetooth headset connected (switches to HSP/HFP profile)

Issues & Assistance Networking Support
1

Hey,

Sorry for the lengthy title, it’s hard to summarize this issue briefly.

This problem has occurred on every Arch based distribution I’ve tried (including Arch, Cachyos, and now Garuda Linux). Whenever I join any kind of voice chat for example, Google Meet or similar platforms while my Bluetooth headset is connected, my Wi-Fi connection drops completely. This makes me unable to join the meeting, and my entire system loses internet connectivity, not just the browser.

However, if I disconnect my Bluetooth headset, the issue doesn’t occur and my Wi-Fi works normally.

I also noticed that whenever I join a voice chat, the system automatically switches my Bluetooth audio profile to HSP/HFP (mSBC codec). I’m not entirely sure why switching to this profile affects my Wi-Fi connection, but it seems directly related.

If I manually switch the audio profile back to AAC or SBC-XQ while connecting to the meeting, my internet starts working fine again but in that case, my headset no longer stays connected to the voice chat.

Here’s the journalctl log:

I know this isn’t the same issue, but wondering if it’s related/connected:

Others seemed to have complained on a manjaro forum:

Hi there @vigr.

Unfortunately your qca9377 Wifi/BT combo chip is well known for having connectivity issues.

There are a bunch of fixes that are known to help improve connectivity with your qca9377 network adapter posted on the following thread:

In addition, I would be sure to disable the Random Mac Address feature of Network Manager. There are several different methods to accomplish this. A quick search should give you the options available to do this.

Adding additional kernel boot parameters often helps improve the performance of the qca9377 network adapter.

The following command will automatically add these helpful kernel boot parameters to /etc/default/grub:

sudp cp /etc/default/grub /etc/default/grub.bak && sudo sed '/^GRUB_CMDLINE_LINUX_DEFAULT=/s/"$/ ath10k_core.nohwcrypt=1 pcie_aspm=off "/g' -i /etc/default/grub

After adding the above boot parameter(s), run:

sudo update-grub

Then, reboot, and test your connectivity for any improvement.

You may want to test several different workaround methods, if none of the above suggestions help with your disconnect issues.

Try this:

Before you intend to place a call using Google Meet (or some other software), connect your Cellular phone via USB cable to your computer. Through your phones settings utility enable “USB Tethering”.

A new connection name should appear in your system tray’s network connections applet. Switch to this new connection and test your internet speeds via phone tethering. Assuming you have a cellular data plan, and that your speeds are sufficient for internet conferencing this may allow you to workaround your disconnection issue.

Your other option that may be easier, but will cost a bit of money would be to purchase a separate USB Bluetooth Bluetooth dongle for your internet conference calling.

Physically separating your WiFi chip from your Bluetooth chip can help resolve conflicts between WiFi and Bluetooth. Both WiFi and BT use the same band for transmitting their signals. On problematic combo WiFi/BT chips such as yours this often results in disconnect or speed issues. Physically separating the two chips can help in these type of cases. It may be beneficial in these type of cases to connect the external BT dongle via a short USB cable. Any extra separation between between your WiFi and Bluetooth transmitters can help improve signal clash.

Obviously, neither of these methods are a proper solution, but these workarounds may at least provide you with a working option until a proper fix is released.

I know that’s a lot of stuff to digest, but hopefully something there will help with your disconnect problems.

Good luck finding your solution.

Thanks, you were right. The issue is specifically tied to my Qualcomm Atheros QCA9377 chipset. Unfortunately, my Bluetooth and Wi-Fi share the same antenna and both operate on the same 2.4 GHz band. This causes interference when Bluetooth uses SCO (Synchronous Connection-Oriented) audio for calls, which affects Wi-Fi connection.

These posts confirm the issue:

Luckily, I was able to resolve the problem by switching my Wi-Fi to a 5 GHz channel. That way, Wi-Fi and Bluetooth operate on different frequency bands, eliminating the interference.

Thanks again for helping me identify the root cause :saluting_face:
