O/T : Windows WIFI not connecting

[techlists at phpcoderusa.com]

Hi,

Need some help.  My wife's computer again.  All was well until she tried 
to surf the Internet this morning.  This computer has been configured on 
my network for over 3 years.

It is a Win 10 Pro box.

- I tried the windows troubleshooter and it said it was resetting the 
driver.
- Checked my router and the computer shows up in the access control 
list.
- Changed the WIFI password and it says it authenticates and then says 
there is no connection.
- I have a Windows laptop that is configured to use WIFI and it works.
- I cannot ping my wife's computer from my Linux desktop.
- I've cycled everything multiple time.

In searching the Internet it basically tells me to do what I have 
already done.

Any words of wisdom are much appreciated.

Thanks!!
Keith
