Windows 10: Unable to reconnect to my WiFi network

So this laptop last connected successfully about a month ago to my WiFi network with no problem. It's set to connect automatically but there's no connection. I tried to connect manually and it says the network key is incorrect. There's only 1 key. Other devices are connecting w/o any problems. The router was power-cycled a few days ago. I also have a "sub-network" that isn't showing up when I search for other available networks; that network shows up on other devices. It's a Comcast WiFi network . Any advice would be appreciated. Stay safe & healthy.

Anomalous WiFi Reconnection

Wondering what (if anything) this was about: WiFi disconnected on wife's computer.

1. Checked, WiFi itself working.
2. Ran Network Trouble Shooter, which usually fixes such problems; failed.
3. Ran Hardware Trouble Shooter, nothing found.
4. Checked Wireless Card in Device Manager; indicated as working properly.
5. Restarted computer; still no WiFi.
6. Although Notification icon was black, clicked on it to see if anything there, found that the WiFi network was "Secured." Clicked on that, saw that it was set to connect automatically, clicked on that, failed. Tried once more, failed, so deselected automatic connection, clicked again, and WiFi was reconnect instantaneously.

I think that that covers most, if not all of the steps I took to fix the problem. Any idea as to what caused this, and as to why non-automatic reconnect worked without even asking for the router's password?

 

Wireless Network

Thanks for trying the steps again. It's now clear that the problem is on your router. To reconnect your laptop to the network, we suggest that you set or specify the channel of your wireless network. If you can access your router's user interface, set the
channel to either channel 1, 6, or 11. Once done, remove your WiFi network from your preferred network list, then reconnect.

Let us know the result.

Regards.

 

Can't uncheck WIFI "Connect Automatically"

Hi,

Have you tried removing the network from the list? Your network credentials may still be saved on your Wifi settings.

We suggest you to remove the preferred network and reconnect it. Follow the steps below:

• Press Windows icon.
• Click Settings.
• Select Network and Internet.
  
• On the left pane, click Wifi.
• Click on link Manage Wifi Settings.
• There is prompt, click on Manage known networks
• Select the network you want to forget.

Once you remove the network it will no longer appear on the list. You may need to reconnect it, if you want.

Let us know how it goes.
