Windows 10: Intel 7260 AC Wi-Fi adapter

I have a Dell XPS 8700 that came with a Dell 1704 A/B/G/N Wi-Fi adapter. This is a rebranded Broadcom card.
After Windows 10 Pro conversion since July 2015, the Wi-Fi adapter worked fine but if I activated Hyper-V with Windows 10 Pro, I got BSODs with error 0x50 like:

On Fri 1/22/2016 4:14:34 AM GMT your computer crashed
crash dump file: C:\WINDOWS\Minidump\012116-7046-01.dmp
This was probably caused by the following module: bcmwl63a.sys (bcmwl63a+0x8EA6F)
Bugcheck code: 0x50 (0xFFFFF6FB400037A8, 0x0, 0x0, 0x6)
Error: PAGE_FAULT_IN_NONPAGED_AREA
file path: C:\WINDOWS\system32\drivers\bcmwl63a.sys
product: Broadcom WiFi Driver wireless driver
company: Broadcom Corp
description: Broadcom WiFi Driver wireless driver
Bug check description: This indicates that invalid system memory has been referenced.
This appears to be a typical software driver bug and is not likely to be caused by a hardware problem.
A third party driver was identified as the probable root cause of this system error. It is suggested you look for an update for the following driver: bcmwl63a.sys (Broadcom WiFi Driver wireless driver, Broadcom Corp).
Google query: Broadcom Corp PAGE_FAULT_IN_NONPAGED_AREA

I even run memtest for a long time to rule out memory problem with 8-9 passes.

I experimented with several versions of bcmwl63.sys. Again it works fine with Windows 10 Pro but as soon I work with Hyper-V I still get BSOD occasionally..

Frustrated, I purchased and replaced the Dell 1704 card with an Intel 7260 AC. I just let Windows 10 installed the driver.
After one day of working Hyper-V with Windows 10 Pro. It is still running fine!

I am not solving my problem just side step for now! Have any one have similar experience?

I am at Windows 10 10586.71 with this XPS 8700.

This was such a drag - eventually fixed by updating Wi-Fi adapter driver - Intel Dual Band AC 7260. Search automatically did not find it - had to download from Intel Support site.

 

"Error 1075: The dependency service does not exist or has been marked for deletion"

There seems to be an Intel site devoted to that adapter...

Support for Intel® Dual Band Wireless-AC 7260

Intel® Dual Band Wireless-AC 7260

I hope you spot something helpful there. Good luck, & keep us informed.

 

That would not surprise anyone with Hyper-V, that the Broadcom chipset is causing it to crash. I have two laptops with the 7260 mini-PCIe cards in them and have had zero issues. I did have to place the second antenna up in the Battery compartment, only because I did not feel like tearing apart the lid to place it up there.

 

Wow, it is going toward the 72 hours of operating Wi-Fi with Hyper-V without any error!
Beside the absence of bug check error 0x50, Intel 7260 is AC device, so now I am connecting with 867 Mbps instead of 300 Mbps with the old Broadcom chip.

The best $24 I ever spend! Thanks Intel *Thumbs

 

I am guessing you are using AC. I get around 265 with mine on Wireless-N on my Toshiba Satellite C850D-st3nx1.

I can say that doing the change to the better card has been the best money well spent also.
