    Intel Wireless-AC 9260 netwtw08 driver crashes with large upload traffic

    chenxiaolong

      I'm running into an issue where a large amount of upload traffic causes the netwtw08 driver for the wireless card to crash and restart. On my system, it's easily reproducible by copying a large file to a SMB share on the local network. The driver usually crashes after around 10GB of data transferred.

       

      I've included the environment/hardware information and error messages from the event log below. I've also attached the report from Intel System Support Utility as well as the report from the "netsh wlan show wlanreport" command.

       

      Environment:

      • Laptop: Dell XPS 9560
      • OS: Freshly installed Windows 10 1803 (Build 17134.112)
      • BIOS: 1.11.0
      • Wireless card: Intel Wireless-AC 9260
      • Wireless driver and version: Netwtw08.sys version 20.80.0.5
      • Wireless APs: 2x Ubiquiti Unifi UAP-AC-HD running firmware 3.9.54.9373
