When Bluetooth is enabled, Wifi cuts out?

[darkstrike]

Hi all - I have an HP Pavilion TouchSmart 14 laptop running Mint 20.2 MATE 64-bit.

Everything works fine, but I was recently given Microsoft Arc Touch Bluetooth mouse which I can't get to work on Mint. In the process of trying to get that to work, I noticed that my WiFi seems to cut out whenever Bluetooth is activated...? But, when I disable Bluetooth again, WiFi seems to come back?

Like....I can turn on Bluetooth, turn on the mouse, set it to pairing mode, then watch the network drop out on Conky (the network SSID changes to 'off/none'), then it comes right back saying it's connected to my network...but nothing will load at all, say, in a browser or it will load VERYYYY slowly (websites, etc) until I disable Bluetooth again, then the WiFi goes back to working perfectly as normal?

It's not the original WiFi card that came with the laptop (the original one had no Bluetooth), so it's one of those Intel Centrino combo WiFi/Bluetooth cards.

I know the mouse works perfectly on a Windows 10 PC I tested it on, so the issue isn't the mouse. I'm less worried about the mouse yet than the whole 'WiFi cuts out when Bluetooth on' thing.

I have a habit of turning Bluetooth off when I start the PC because I never intended to use it much (until now) and because it saves battery life not having the Bluetooth radio on when I'm not using it, so I've never really noticed the WiFi/Bluetooth issue before until now.

It's very weird...it's almost as if the connection to my WiFi card gets overloaded when Bluetooth is trying to use and everything just dies...even though it's a combo card that has both and that's how it's supposed to work? It's just your run of the mill half-height mini PCI-E WiFi/Bluetooth card.

Anyone have any ideas as to what might be up? Thanks!

Right now it won't even see my mouse....and I know the mouse works as I successfully connected it to 2 other PCs, but my laptop won't even find it now when I have the mouse in pairing mode?

There may be a setting in your router called "bluetooth co-existence mode" check into that.

[darkstrike]

Nope, don't see that anywhere, sadly

Perhaps a newer version of the iwlwifi driver will help. Try this:
Update Manager - panel: View - Linux kernels

Install the latest kernel of the 5.11 series. Then reboot.

[darkstrike]

I'll give it a try this weekend...though I've tried a variety of kernels and none have seemed to make a difference before, sadly...

Did you know that Bluetooth and WiFi 2.4 g are on the Same Frequency Band??

Experiment with changing the Channel on your WiFi router, get it as far away as you can.
when I changed to the 5g WiFi on my laptop, miracles happened.

downloads are faster, 5g is faster, but packet losses are history because there is no competition to the 2.4g channels.

Hi AZ - yes, I was aware. I've tried a few different channels which, sadly made no difference. As for the router, it's on the complete opposite end of the house. I do have 5G in the house, but it's disabled as none of the laptops are 5G capable (only our phones).

What's weird is I use bluetooth in my car with my phone all the time, so I just leave it turned on on my phone. I can have my phone right next to the computer with bluetooth on and the internet works perfectly, it's only when I turn bluetooth on on the computer TOO that the WiFi on the computer cuts out...
