Laptop- Disappearing WiFi Network

Hi there, can anyone help. After using the internet without problems for the last few weeks in our new flat , my laptop connection disappeared during a conference call. I have no idea why. Now when i look for the wifi network it has disappeared. It is still available on my phone, my girlfriends phone and my girlfriends laptop, just not my laptop. Every network in the street i live is displayed and all the local cafes, just not our flat wifi. It seems really bizarre. Any advice would be greatly appreciated. Thanks

'No WiFi Network found'...several months

One fine day, several months ago, all the networks disappeared and only shows "no wifi network found". The wifi network is working on all other devices but my HP laptop with Windows 10. I have tried rolling back the driver, unintstalling and reinstalling
the driver, disabling firewall and anti-virus but nothing works. The properties of the driver show that it is working properly. When running the troubleshooter, it says that a network cable is unplugged. The problem is only with WiFi. I can access the Internet
when I connect a dongle with a USB wire.

 

WiFi Network showing twice in my Windows 10 laptop

I installed Network Certificate of a company in my laptop having Windows 10 OS, which means whenever am in range of company WiFi then my laptop should auto-connect to WiFi and it does perfectly.

My question is about the "WiFi SSID showing twice with a number 2 at side". Please see the following picture for understanding.





Thinking the certificate could be duplicated. I typed certmgr.msc in Run but could see only one certificate listed as shown in following pictures.
