Connecting Bluetooth mouse ruin wifi

Hi guys, this is quite a weird issue.
I’m using KDE neon on an old dell inspiron laptop.
Long time ago I’ve bought a Bluetooth air mouse/ keyboard remote thing and I’ve noticed that when I’ve connected it the wifi, although stayed connected was rediced to few bytes a second (if any).
I moved on and used kdeconnect instead, and rf mouse and keyboard with a dungle.

Recently, I’ve bought a normal Bluetooth mouse and the wifi is still refuced to near 0 when it’s connected.

By the way, when I connect to Bluetooth speakers, it works as expected.

What’s going on? How can I solve it?

Hi - this sounds - to me, at least - like a hardware problem in some combined Wi-Fi + Bluetooth module on your laptop, just based on having a somewhat similar situation pop up on a desktop a couple of years back (and multiple laptops over the years with Wi-Fi issues).

Before digging through a whole ton of system logs and configuration files, it might actually be easiest to try booting into a live USB for a different operating system distribution (ex. Fedora, Ubuntu, etc.). If the issue still occurs while you’re booted into the live environment, then you at least know that it’s not related to your current OS installation - that would indicate either something down in the Linux kernel itself, or a hardware issue.

Thanks for the advice, I’ll try it.
I actually thought at first that it might be a hardware problem, but in that case, I assumed any Bluetooth connection would’ve done it.

I assumed any Bluetooth connection would’ve done it.

If you assume the problem is at the receiving end. But it could be bad mouse electronics interfering on other frequencies. If you have a smartphone connected to wifi, you can test if its wifi is also jammed when the mouse is working near it.
