Dell Wireless 1560 802.11 ac networking unstable

After upgrading an XPS 15 laptop to Windows 10, the wifi networking is nearly nonfunctional at low signal strength. 

When checking the driver property page for events, I see the following message: 

Device PCI\VEN_14E4&DEV_43B1&SUBSYS_00191028&REV_03\346800FFFF00000100 requires further installation. 

Any suggestions on how to fix this?  There is also event 5002 logged multiple times:

The "required installation" event may be a red herring, as the date for it was a few days ago.  The following events are appearing at boot right now:

I have a similar problem.  The wifi connection keeps breaking.  The only real fix is to restart the computer.  I tried turning wifi off then back on, it did not work.


This is an XPS 13 with windows 10.

I found something that may point at the underlying problem.  If I connect to the wifi router in a place with high signal strength, the connection stays stable even if I move the computer to lower strength.  Try putting the computer next to the router, disconnect and reconnect the wifi connection, then move it to another spot.  It's not a fix, but could help narrow down the driver issue.

One interesting clue is that the network operation is much more stable if the System Resource Monitor is running.  To test this, enter the Windows key +R, then type resmon in the run box.  If you see a similar behavior, please post a reply.  It's not perfect, but does seem to extend the time between adapter resets. 

In my configuration I'm connecting to an older router, the D-Link WBR-2310.  There could also be a compatibility issue here, though I can' find anything yet.  Given that this is an older product with a stable set of firmware, the laptop driver should be able to use it without issues.

I've been working with Dell support over the last week.  We installed the Windows 7 driver, dated 11/28/2014, version 6.30.223.259.  This version has fixed the problem.  They say they are now aware of the issue and are working on an update to the Windows 10 driver.  This is on an XPS 15 with adapter name "Dell Wireless 1560 802.11ac."

Definitely a problem with this driver. It's been responsible for my computer crashing. Update it soon please Dell.

We have the same problem on our XPS13 with Windows 10. Hopefully they fix this issue soon, because I'm about to trash the Dell and go buy my wife a Mac. This problem has rendered her laptop nearly useless given how often she has to reset the network adapter.  I finally wrote her a powershell script to do it, but come on... this machine was way too expensive for such a basic service to be so badly broken.

Same problem here!

We have 2 XPS 13 laptops, and on both laptops WiFi is not stable. Similar problems as mentioned above. I have tried many different versions of the Wifi driver, but nothing seems to help. 

Message to Dell:

When will a new Wifi driver be available that fixes this problem?

Please reply!

What finally worked for us was to switch back to the Broadcom driver. Since doing that, we haven't had any network problems.
