    Latest versions (19.1.0 and 19.0.1) of Intel® Wireless-AC 7260 Plus Bluetooth* (7260HMW) WIFI driver (netwbw02.sys) on Win 10 64-bit is causing frequent system crashes

      Hi,

       

      This is really puzzling. I tried both versions of mentioned drivers and all kinds of BIOS and driver settings, still my system would crash, sometimes just upon login attempt. I tried both WIFI drivers versions, e.g. 19.1.0 and 19.0.1, same effect. However, when using Microsoft supplied driver v. 17.15.0.5 the system would stay stable - but not the WIFI connection, which would drop quite often and not able to reconnect to the router; only driver reset using Win 10 network troubleshooting tool would fix the connection albeit only temporarily.

       

      My system info:

      This appears to be a typical software driver bug and is not likely to be caused by a hardware problem. This problem might also be caused because of overheating (thermal issue).
      The crash took place in the Windows kernel. Possibly this problem is caused by another driver that cannot be identified at this time.

      If requested, I can provide with the minidumps (as listed above) or full memory dumps, as the crashed are so frequent that are easy to reproduce. Can this be actually escalated to development?
