XPS 15 9560 Bluetooth Problems

It sounds like you have pretty much tried all the steps I would recommend, something else I would try is to download the 1535 drivers directly from Qualcomm here 

On a side note, the 8265 should work fine, the only other times I have seen a card not work (be whitelisted) is if it was an Intel card from a different system like an HP/Lenovo card in a Dell etc (and vice versa). If the 8265 does not work and comes up with a code 10 error you might need to re-order the card for a Dell specific version, but I haven't seen any reports like this lately so I think it will be fine.

Let me know if you have any luck with the Qualcomm drivers, or if the Intel card resolves   this.

Best regards,

Brad 

Have you managed to resolve this yet? I've got the exact same issue. I received my laptop 2 days ago. I install the drivers, it works for a very short time, then it starts to cycle disabling and enabling itself.

Something which hasn't been done is to go to Device Manager and look at the properties for the Bluetooth Device.  There is an Events tab which my show that that device is doing.  It is a small window so make sure and scroll to see the entire listing and select a particular entry to get details.

The Event Viewer may also have some type of entry related to events surrounding the disconnects.

Just for testing, if you are in an area with other Bluetooth devices you might try putting them on airplane mode to shut off those radios.

But I agree, changing out Wi-Fi devices should not be a problem.  My 9365 came with a 8265 and I put a 8260 in an Inspiron which came with an 3165.  Make sure and get the correct form factor.  The M.2 cards come in two widths, one has both antenna connections on one side.

Thanks Brad. The OEM drives helped a lot. It's still not 100% what I would expect so I am still proceeding with the swap but it's definitely 99% better. An occasional disconnect but devices stay paired and do not require reboots to re-establish connectivity.

I did, I installed the OEM drives from Killer (not from Dell's website). Although significantly improved, I'm still swapping out the card for an Intel. Good luck!

I installed the Intel 8265 and I am experiencing much better Bluetooth and Wireless connectivity.

If I install the drivers from the Dell website or the Qualcomm website, yes it works for a short period.

After a wile however, it stops working, and if you look in device manager you can see the device constantly enabling and disabling itself every couple of seconds. I goes from:

"Windows has stopped this device because it has reported problems"

To:

"This device is working properly"

On the Qualcomm website, they say this device is no longer supported. Why has a brand new, high-end laptop got such an old, no longer supported Bluetooth card?

My Microsoft Arc Mouse will drop off at least a half-dozen times a day. Have to "reboot" the mouse so my XPS will pick it up again. My Bose Bluetooth speaker will stutter and lag constantly, while streaming music. None of these things happened on my Surface Pro 4, which honestly, was more reliable all-around....and it had its own set of problems. I'm able, but not willing, to spend the time re-shuffling drivers and troubleshooting. I spent $$$ on this thing so I'd have a work laptop that just works well. Period. All drivers are latest and those listed for this device on the Dell support site. Fix the issues guys, or it's my last Dell!

I saw another thread regarding Killer Wireless.  It may not be related to the situation here but if it is maybe the driver linked from a Killer Rep. would help.

I tried the same thing with almost the same results.  When I look at the Device Manager, Bluetooth has disappeared completely and never comes back.  Sometimes, if I reboot, it comes back.

I tried that, but it had no effect.  I reinstalled the Dell drivers and shutdown the computer.  The next morning when I rebooted, my Bluetooth was back?!?

I have the same issue, the bluetooth dissapears after being used for a couple of minutes, I don't even show as being installed, like there is no hardware for it. I have to re-start. I contacted Killer wireless and they sent me the following email.

"Luis Rivera,

We have seen a few cases of this reported lately. We have confirmed that this is due to non-enumeration by BIOS/motherboard. This can be fixed by draining power to your machine fully.

There are 2 ways to do this:

1. Battery Drain reset: Let the laptop use all battery power, thus emptying the battery and allowing power to the motherboard to actually allow a reset of the device enumeration

2. Unplug power and disconnect the battery: The Alienware notebooks have their battery connector in an easy to access place, usually only requiring removal of 2 screws to remove the bottom access panel. You can then disconnect the battery, accomplishing the same result as #1 without the need to take time to drain the battery.

Leave battery drain/disconnect for a few minutes, then reconnect/power on. Bluetooth and Ethernet adapters should then show up normally.

Anthony Davis

Anyways, I think I'm going to end up buying the Intel® Dual Band Wireless-AC 8265 and replace the Killer 1835.

I am having bluetooth problems with my xps 9560. When I turn it on, it would not find any of my bluetooth devices, it just kept on scanning without finding anything. It's been frustrating, as it worked before, but just stopped working all of a sudden. Hope anyone can help or suggest a stable driver to download and try, thanks!

Hi mhcox. This is my first post, so apologies if I do something wrong... If someone can improve on this description, please feel free to add your comment!

I have the exact same problem with my XPS-15 9560 running Windows 10. About once a week my Bluetooth devices suddenly stop working, and Bluetooth completely disappears, not caused by anything I've been able to sort out yet. Like you, there isn't any Bluetooth section in the Device Manager, so I can't change any settings or check drivers.

With the help of Dell support, I updated, installed, reinstalled, and rebooted several drivers and the computer, but still no Bluetooth in the Device Manager. Finally, the support rep had me run a boot diagnostic, and it turned Bluetooth back on. I've done this same process a half-dozen times now, and it works consistently.

The process takes about 5 minutes. It's a workaround and not a permanent fix, but until Dell fixes this problem I'm happy to at least have these steps:

1. Shut down the computer and wait about 10 seconds.

2. Turn the computer back on and immediately start tapping the key repeatedly.

3. Select “Diagnostics” from the menu that appears (this will start a system test).

4. During the test, you’ll have to answer a couple onscreen questions about what you see onscreen.

5. After a few minute it will finish several tests and ask you about running the 1hour+ of “recommended” memory test. Select “No” so you DON’T run the additional test. I don't think it would hurt, but it isn't necessary for this process.

6. In the top right corner, select “Exit” and say yes to “exit and reboot.”

7. Once it reboots and you’re logged back in, check in the Device Manager and (fingers crossed) Bluetooth should be back, although your devices may still not be working.

8. To get your devices back, tap the Windows key and type “Bluetooth”

       a. Select “Bluetooth & other devices” setup to get into the Windows setup

       b. Sometimes the devices re-appear if you just turn them on and off.

       c. If that doesn't work, you have to remove them and re-discover and install them

I'm sure this isn't the fix you were hoping for, and I bet you share my hope Dell finds a fix for this soon. At this point I can't rely on Bluetooth devices for my work, since I can't afford to say to meeting attendees "Hold that thought for 5 minutes while I fix my computer so I can continue my presentation!"

Hope this helps!
