Yes it's a known issue that affects some systems, the root cause is that the windows driver is just a repackaged Win 7 BCM95342 mini PCIe version and is not specific to the M.2 BCM95342Z version running on Windows 10. The driver file bcmwl63a.sys crashes when a badly timed interrupt occurs (confirmed using an oscilloscope on the interrupt line) .
However, it only seems to do it on some systems and/or BCM95342Z suggesting that the interrupt line level logic on some cards is tighter than on others ... I did a lot of research and investigation on the issue but never found a solution ... in the end I gave up on the BCM95342Z (DW1560) and replaced it with a DW1830,
I posted my findings in this post:-
The BCM43602 WiFi chipset on a DW1830 card is a much better WiFi solution with MacOS native support but you must add a 3rd Antenna, Bluetooth is handled by a BCM20450 chipset which supports BT4.1LE thus allowing much better continuity and handoff compatibility.
Trust me you wont find a solution, save yourself the pain and get a DW1830, you may (like i did) have to tape the enable/disable pins 54 & 56 which i covered in the above link.
I've replaced my card with another (nearly) identical Chinese DW1560 and downloaded the following drivers from the Dell site "Network_Driver_71T5D_WN32_7.35.340.0_A03.EXE" (google is your friend) which is the latest DW1560 Windows 10 driver Dell provides for any notebook. Run the executable, extract the files and manually replace the current broadcom driver with the DW1560 one. After that I disabled "Minimal Power Consumption" as well as "Wake On Magic Packet" and "Wake on Pattern Match". I haven't had a 'freeze' in two days. Since I've changed several things at one time I didn't mention it since it didn't particularly narrow it down to one thing and it could even be that the new card is less tricky than the previous one... Also I’ve never encountered the issue in any OS other than Windows so far.
