Windows 10: All wifi networks showing except mine

My friend had a issue with his computer so I tried to help him fix it, he bought a new pc and cant use it because of his issue. We have so far tried, resetting this pc and removing everything, cleaning the drive. In cmd prompt he have tried,sfc /scannowDISM /Online /Cleanup-Image /CheckHealthDISM /Online /Cleanup-Image /ScanHealthDISM /Online /Cleanup-Image /RestoreHealthand we also tried updatting and rollbacking the networth adapter.And we triednetsh winsock resetnetsh int ip resetipconfig /releaseipconfig /renewipconfig /flushdnsand chkdsk

Wifi Networks not showing

On my Laptop if I wanted to change the wifi connection I would always see a list of the available networks when I selected the Wifi icon on the task bar.
Since the last major update to Windows 10 I find that when I select the wifi icon I only see the current connection





To see other networks within range I have to open the 'Network settings' and choose 'Show available networks' - then they show up.





Does anyone have any explanation for this - or possibly a 'fix' to show them all from the taskbar again.

 

WiFi appears in Manage Known Networks, not in Show Available Networks

The list of WiFi connections shown when you click the WiFi icon in the taskbar is a list of all the signals that can currently be seen by the WiFi adapter. The list in Manage Known Networks is a list of all those you have previously successfully connected to, whether or not they are currently available.

The only plausible explanation is that for a while that WiFi signal had been turned off.

 

Cannot connect to home WiFi network

I upgraded to Windows 10 and ever since then my computer can't find my own home wifi network. A bunch of available wifi networks will show up, but not mine. I don't have it hidden and it shows up on my Blackberry & my Samsung Galaxy. Ethernet works fine, but not wifi.

I've tried the following:

• Use device manager and scroll to network adapters and expand it and select your wifi card. from there hit uninstall but do not remove the driver. after that look up top for a computer with a magnifying glass and it will scan for changes which will then reinstall your driver for your wireless.
  
• I tried to "manually connect to a wireless network" which still didn't work (I could name it, and enter the password) but nothing would happen.
  
• I've upgraded the drivers of my Dell Centrino card and I still don't see my wifi network.
  

Any suggestions on what to do?
