Qualcomm Atheros QCA61x4 wireless network adapter. WiFi stops working when you upgrade driver.

My wifi stops working on my "Idea Center 700-25ish" computer when you upgrade the "Qualcomm Atheros QCA61x4" network adapter driver to the lastest driver version "12.0.0.312" dated "5/23/17".  This happens on either a direct driver download from the Lenovo support site or doing a windows upgrade to the "Fall Creator's Update" on windows 10.  The only way I found to work around it is to back out of the upgrade.  Since Microsoft is no longer supporting my version of windows 10, I had to reinstall the "Fall Creator's Update" and start using an Ethernet cable to access the internet.  My Wifi is still not working.  Does anyone know how to fix the Wifi problem?

Re: Qualcomm Atheros QCA61x4 wireless network adapter. WiFi stops working when you upgrade driver.

Hello Kim77

Thanks for using the Lenovo forums.


I think the issue will be with the Creators update, I can`t see your unit listed here(Or I`m just blind):

https://support.lenovo.com/us/en/solutions/ht503655

 

So I would recommend that you get back to the previous Windows update, and see if the unit will work there for you.

 

Hope this helps, let us know how you get on.

Please let me know if you found a solution for bluetooth missing. Lenovo has no idea, Microsoft says it is Lenovo problem. Tried many fixes, nothing working.

 

Thank you

Try shut machine down and remove power cable for 30s. Then turn machine on and all should be ok. If happens again later repeat procedure and update drivers of wifi and bluetooth to newest versions both. Maybe removing powercable is not enuf if u have battery, on my acer works but lenovo can need remove battery too.
