Intel Wireless Adapter Driver having sporadic disconnections


I've had a Gigabyte GC-WB867D-I (Intel® Dual Band Wireless-AC 7260) wireless adapter for about 2 years now, and never had any issues with it. It's only until recently that I'm having various disconnection issues that seem to be heavily software related. At random times during a day (sometimes having breaks of several days with no occurence of the issue), my PC will freeze up two to three times for about 2 seconds, over 10 seconds. At the same time, my wireless connection gets dropped, as if the adapter had gotten disabled. When having Windows 10 troubleshoot the issue, it generally tells me that "The Default Gateway was not available" (if I remember correctly), or sometimes that an ethernet cable wasn't plugged in correctly.

I've attempted installing various versions of the Intel Wireless Adapter drivers to solve the issue, but nothing seems to work. I formatted my PC about 4 days ago as well, hoping it might help, but it apparently hasn't. I also bought another wireless adapter originally, expecting the issue to potentially be hardware related, though that adapter seems to be having issues with connection speed, almost dividing my speed by 10.

I'm at a loss of what I could do here, and would really love if someone could help me out here.

Got the info from this forum:



The problem is the newer Intel drivers, as many have pointed out.


Now to those remaining, take the steps that intel techs pointed out months ago, which involves:


* removing all intel network software from your 'add/remove applications"


* rolling back your driver version. This is done by going uninstall driver in device manager and choosing 'also remove software' tick box.


* Rescan again so it shows again, then repeat, and repeat, and repeat, till you get sick of repeating!


* Use CCleaner and clean your registry of any shit leftover, use windows disk cleanup etc. (good practise)


* Rescan till nothing shows, restart, repeat.. (now they didn't tell you about this repeating! hehe)


* Most of those who are onto it, won't have to repeat so much, but if you have been stuffing around trying to fix this, then there is a lot of rubbish to clean.


* Reboot


* It will reinstall it, check the version, is it the MS version? We are looking for version: or simular 17x version.


Now you check your wifi, and it should be mint.


Now to stop Windows Update reinstalling the shitest driver from intel again, you can google this:






To anyone still having disconnect issues with the ac-7260 module, please try falling back on the driver version. Doing so has worked for many, including myself.


You can get drivers from Microsoft (Update catalog) here: https://www.catalog.update.microsoft.com/Search.aspx?q=ac-7260 Try drivers prior to 18.33.x.x.


If it works for you, please leave a comment here so others will know.
