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

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

Event log:

  • Information 10/21/2018 5:27:38 PM Netwtw08 7003 None - 7003 - Roam Complete

I'd also like to point out this issue does not occur if I use an Intel Wireless-AC 8265 in the same laptop.

Hello chenxiaolong,

 

 

Thank you for posting on the Intel ® communities.

 

 

I can see that you are having problems with an Intel ® wireless adapter when transferring big amounts of data.

 

 

Regarding this, I would like to begin by mentioning that you need to first get in contact with your manufacturer before upgrading or changing the wireless adapter. More information about this can be found here:

What was the original wireless adapter? If the original one does not give problems but the one you installed does then it means that it could be a software/hardware incompatibility which is why we recommend to get in contact with the manufacturer before any change or upgrade.
