Windows 10: My wifi keeps connecting and disconnecting at will and at random times

Since I've performed a clean installation of Windows 10 in my Acer Laptop I am experiencing problems with the wifi. Sometimes I spend hours surfing the web with no problem and suddenly Windows are disconnecting from wifi, then they may reconnect maybe not. I switch the wifi off and then back on and the wifi may continue working for another 3 or 4 hours but maybe not. I've tried many different driver updates for my "Qualcomm Atheros AR956x Wireless Network Adapter" but nothing fixed the problem that pops completely at random. I've searched many forums but nothing solved my problem. I'm sure that my modem is working properly because all smart devices are connecting with no issues and another laptop with Windows 10 as well.


Apart from that, the laptop before the format had no problems with the wifi. I would appreciate it if you could help me!


Here is the error with event id 411 that I found on device manager:

Wifi connection keeps disconnecting

Hey, guys, so I go to college and I use my school's Wifi. My roommates don't have this problem so it's just me. Whenever it disconnects, I go to the Network and Sharing Center to diagnose it. When I diagnose it, it fixes it and I get this (attached an image). But after awhile, it will disconnect so I will have to repeat this process multiple times a day. Can anybody help?Thanks.

 

Wifi keeps disconnecting seemingly at random intervals

I have a brand new HP Pavilion laptop that I received for Christmas. Ever since I first installed windows and connected to the WiFi I have had an issues where it disconnects at random intervals. Sometimes its hours in between and some times it is minutes.
When I first lose connection to the WiFi the status still shows I have a strong connection, but when I disconnect it first says the WiFi is turned off and takes several attempts to reestablish connection.

 

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
Windows version 1909 (OS Build 18363.592)
