Lenovo laptops will not stay connected to wifi

We have several Lenovo laptops, mostly Yogas.  All are having the same issue.  They connect fine to our (and other) wifi network, but the drop after a few minutes.  We've updated the drivers, turned off power saving, and it still happens.  We've tried limiting the dual band to a single frequency, no luck.  Anyone else have this problem.  We have a variety of other laptops by other manufacturers that work fine.  We like the Lenovos better other than this problem.

Ugh, I swear this is a Windows 10 update issue. I have been having the same problem with two of my older computers since November. One a Lenovo, one a Dell. I have not been able to resolve the issue properly, but if you go to device manager and delete the wifi driver, when you restart, it will reload one for you. That has fixed the issue on one of my computers.

Yes, we had similar problems with some Dells and deleting it did solve it.  But no luck with the Lenovos.  Thanks!

For Lenovo notebook, there is a wireless security app which is bundled with the notebook. Have you checked what apps are installed?

Yes we disabled all unnecessary apps.

We never found a solution.  However, we replaced the wireless nics on the affected laptops, and they are working correctly.  At least for now.  
Thanks
