I'm writing to you if you have advice for a weird problem I have here with a bunch of new Lenovo Yoga P40 (with wireless card Intel 8260NGW) working on wireless.
This is the problem:
Have you ever seen something like that in your experience?
We've had a few reports of connectivity issues after the Windows® 10 Creators update. In addition to what you have tried, you might want to consider the following actions, as they have worked for other users:
1. Disable RSC and Packet coalescing: /thread/114823 Intel 8260 + HP ZBook Studio G3 Connection issues. Somewhat driver dependent.
2. Change the Default Maximum Segment Size in the Wireless controller: /thread/115425 Low download speed with AC 8260.
Please check the related threads for details and let us know if this helps.
Please let us know if there has been any progress about this issue.
We recommend you to make sure your Windows* is up to date, including patch KB4022716. Other users have reported that it address connectivity issues at the OS level.
