Windows 10: wifi has turned off and will not look for wifi after win 10 update

Error 0x80072af9 is coming up

Windows 10 wifi not turning on Acer Aspire laptop

In order to get the list of available wireless networks, you have to:

1. Switch on Connect to suggested open hotspots (see the screenshot in question);
   
2. Click on Wifi icon in the right corner. Now you have your networks back.
   

After that the parameter from Step 1 can be turned off, networks will be listed normally after restarting Wifi.

P.S. I feel rather stupid at the moment. I thought that open hotspots are passwordless hotspots and so are presumably not very safe. So of course I've turned that off during installation.
Really hard to see any logic in this case.

 

Acer laptop Win 10 Won't Turn On Wifi (used to work)

I'm working on a laptop for a client. It's an old Acer 5253-bz692. WiFi was working until the client came to pick it up (of course). I updated to WIn 10 1703 and WiFi continued to work. The only thing I did that could be related is I upgraded the RAM, which is nearby the WiFi card.

Here's what I've done so far:

1. Settings > WiFi Settings > Turn On WiFi (it shows as off). That
   switches the toggle, but never turns on. If I reload the WiFi
   settings, it shows as off again.
   
2. It does have a keyboard shortcut to enable/disable WiFi (Fn + F3), but that does nothing at all. (the other F-key hotkeys work).
   This machine does not have a hardware switch for WiFi.
   
3. Reinstalled WiFi driver.
   
4. Replaced WiFi card, installed drivers.
   
5. Disabled power management (don't allow Windows to turn off wireless)
   
6. Found a couple posts that said with Intel cards to disable 40hz. Now explicit setting for that here, but found one similar and changing it did nothing.
   
7. I don't see anything in the BIOS for enabling/disabling it.
   
8. Restarted machine multiple times. Also pulled battery and cord and held power for 30 seconds.
   

Any suggestions?

 

Wifi network not appearing after recent Win 10 monthly patch

Someone else on another forum suggested I switch the wifi freq on my Android Nexus 5x. So I switched it from 5ghz to 2.4 and it worked! Problem solved. Now my Nexus hotspot is again appearing in my Win 10 list of available wifi networks. So problem was with Android and not Windows.
