I have been using the laptop with my Logitech MX Master 2S mouse for quite a while and things work just fine. But recently, the Bluetooth is not working very well. The Bluetooth adapter just disappear while I had my mouse connected and used for a while.
And the Bluetooth adapter disappears across ubuntu and windows 10 together every time, which indicates it is a BIOS or hardware problem. The only solution that I found useful is to reinstall the bios update released on 21 Sep, but it only helps for a while.
I found that quite a number of people have experienced a similar situation, yet their solutions do not apply to me.
Solved! Go to Solution.
I have followed the later instruction at
https://www.dell.com/support/article/us/en/19/sln306440/killer-n1535-wireless-firmware-manual-update... and for 90% it seems to be working fine. The only times when it sometimes fails is when i close the lid.
New firmware versions seem to improve over time is my feeling.
I hope this helps.
Yes!! my mouse lag in some time as well. I have just had the bios updated to 1.5.0 today but the problem persists. Even worse, the wifi dies with the Bluetooth, it makes me feel that the problem is the wifi card itself.
I have the same problem with Bluetooth. It will just stop working while typing or when machine hibernates, it wakes up without Bluetooth. I have now made 4 calls to tech support. They seem to fix it temporarily only to have it reoccur.
Dell needs to fix the bios or whatever they need to do resolve this problem. Tech support offers the lame excuse that it disconnects due to RFI. That explanation is utter rubbish.
Thanks for posting. Apologies that your system is not performing as expected.
Your post indicates you have the same problem as the original poster. Does this issue occur using other bluetooth devices such as speakers, or is it only the Logitech mouse?
Here is information from the Dell knowledge base you may find helpful:
If the system is under warranty, please contact me privately. Be sure to include your personal information (name, address, telephone, email) and your computer's service tag number in your message. Thanks.

I upgraded to a newer version of the wireless firmware and the problems have gone. My Wifi and bluetooth were failing reguarly. (same mouse)
When doing a dmesg I noticed the firmware crashed.
I followed the instructions on:
Using the firmware
But check your version (lspci |grep Network)
Has any one have any solution?
I got my XSP 15 9570 by the end of January 2019 and I've only used it for little over a month, and today my Bluetooth also disappeared on me. All drivers are updated to its most recent versions.
I opened up device manager and Bluetooth is not there, ran diagnostic on line from dell support website and it too, says the device is not present.
I then proceeded to call dell technical support, but this is what really got me! The tech support said this is not a hardware issue and that if I choose to cotinue, I will be charged because bluetooth is a software problem!!!
I asked for clarification, he said that any thing physical that I can touch would be hardware, and bluetooth is a software problem! Seriously? so if I have a drive failure, and that my fingers cannot physically touch the drive because it is inside my computer, it would be a software issue as well?? This is absolutely rediculious.
Same issue here with my XPS 15 9570. My bluetooth just disappears when my computer wakes up. Despite restarting, shutting down etc, it won't start again. 3 calls to the TechSupport they never really know what to do, eventually it starts back up randomly but no clue how.
Someone came and replaced my Killer wireless adapter but nothing to do its doing it again.
This is utterly annoying. It seems to be a recurring problem that is not taken care of.
For my notes, Click my name and private message me the pc service tag number as well as your registered name, email address, and phone number.
