Windows 10: Why does my WiFi keeps disconnecting and disappearing?

After a Windows update my laptop started to disconnect from the wifi and could no longer connect to the network also the Wi-Fi option would occasionally disappear. I contacted support and tried to help me but it keeps doing the same thing.

• If you have an identical laptop try comparing the wifi and security settings of the one that does not disconnect with the one that does. If you find any differences change the settings of the one that does not work to the one that does.

• If you do not have an identical laptop see this post and the three replies for possible solutions: Wifi disconnects every 5 minutes.

@Samuria : If you have any suggestions please reply.

 

WiFi keeps getting disconnected

Man do this steps one of that works for 99%

1)can your machine connects to another wifi network
if yes restart or reset your router after that go to your settings and click forget your wifi network as you can see in the picture and try to conect from start




2)if you cant conect anywhere then burn an ubuntu live cd,boot form ther and check if you are be able to concet in your wifi from here .if yes,then you have a software problem with windows,your settings or whatever it is and you need to unistall your drivers and make all windows updates for your machine .
if no then probably your wlan card is dead unscrew your laptop and check if the wifi_card is hot if yes try to find another wifi card or buy a usb wlan card as i did when i have this problem for me this works fine http://amzn.to/2fQqzK8

 

wifi keeps disconnecting from the wifi network

My laptop on wifi network keeps disconnecting frequently.
I am not able to understand what is the problem. While my mobile phone is
always connected on the same Wifi network.










Here are a couple of screenshots how I have to restore the connectivity each time.



















Now the problem is each time I go and disable the connection manually and then enable it does restore the connectivity. Why should I do this ? What is the problem as what is happening.

I thought power management to be a problem so I checked
How to Check if Connected or Disconnected Modern Standby in Windows 10
Here is a screenshot of powercg /a on my system



30 days before reading this tutorial Add Networking connectivity in Standby to Power Options in Windows 10 I had added the option to add network connectivity in standby mode. By using the following command powercfg -attributes F15576E8-98B7-4186-B944-EAFA664402D9 -ATTRIB_HIDE
as mentioned in option one of tutorial.
However if you see the powercfg /a output
my system does not have support by firmware
Code:

so I hope that did not work. Later on after all this my system performance was not good due to other reasons.
So I used media creation tool and on that there was an option to upgrade I choose that, the laptop seem to be formatted for system files (that is my understanding if something else happened then I do not know).
All the settings and apps and device drivers were present as it is.
I again after a couple of days used media creation tool



So all settings I think got erased.
However this is not the cause of my problem I am just mentioning to understand what I did.
2 things I want to know
1) What is the cause of my network connectivity problems while mobile phones are connected and they don't disconnect in this Wifi network but Laptop does.

2) How to backup my existing device drivers if I format the system.

I am on
