WiFi interferes with Bluetooth audio

I am using Kubuntu 22.04 and whenever I connect to a bluetooth device while the wifi is ON , the audio becomes choppy and jittery. Bluetooth audio keeps dropping for about few seconds.
If wifi is disabled bluetooth audio is stable.

The wifi and Bluetooth are integrated into the same chip and both work on 2.4 GHz.

Device adapter: Broadcom 802.11bgn bcm43142

Thanks
 


It's really unlikely that they really interfere with each other, unless it's a really bad chipset.
Yes, they both run at 2.4ghz. (Wifi can run at 5ghz also, if you have the right chipset)

But in reality 2.4ghz isn't broken down enough. There are multiple channels in this range.

How to Choose the Best Wi-Fi Channels for Your Network

Wi-Fi networks can support ten or more channels. If you are lucky, they all work. If not, here is what you need to do with wireless channels.

You can choose which channel you want to use for each protocol.

Still the same issue. And I don't think it will solve the issue as I have to keep changing the channel for every wifi the device is connected which is not possible.

Some cheaper WiFi cards have Bluetooth and WiFi coexisting on the same circuit hence the audio problems I bet if you switch off the WiFi and just run Bluetooth it will be clear and vice-versa - If there is a problem with WiFi, which is more common than manufacturers will normally admit, disabling the laptop’s internal WiFi and using a USB WiFi adapter can often overcome such problems, while Bluetooth remains through the original circuit.

Yes, this is the case but this was not the case when using windows. Bluetooth and wifi both worked fine when I was using windows. Is there something related to drivers?

Please install inxi in your kubuntu install
Code: 
sudo apt install inxi
once installed run this command and post the output back here so we can see what your dealing with.
Code: 
inxi -Fxxzr
As already explained on some chipsets the two are run together on the same chip. And thus the problems. Often times it works in Windows because the Hardware Manufacturer designed it to work with the closed source windows drivers. But unfortunately many time that Manufacturer does not release it's closed source drivers so Linux devs can replicate them. Thus they have guess by trying to back engineer the drivers. This works most of the time but with some hardware it's not too good.
The advise by @Lord Boltar about getting a usb wifi stick maybe the only option to get it working in Linux. But list the info requested and we will see.

That broadcom card has been problematic for a few years now.
This Mint thread may be of help even though it is a little old.

follow the instructions give by JeremyB.
If that does not work I would get the USB wifi stick.
Make sure it's compatible with Linux though not all are.

Thanks. BTW I've already done the step.
Seems like the only solution left is to get a WiFi or a Bluetooth dongle.
