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:

   Standby (S0 Low Power Idle)
        The system firmware does not support this standby state.

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)

The first question that I have is this: How close is your laptop to your router? This little nano-WiFi adapters tend not to do very well over distance since the antenna is so small. Do you find that you lose the connection more often when you are not near the router?

Second, make certain that you have the latest driver for your adapter. Looking on the D-Link Web Site I see that there are 3 revisions of this device. For the latest revision, they just put out a new driver last month.

How close is your laptop to your router?

7-8 meters

Do you find that you lose the connection more often when you are not near the router?

not much of this observation

please give me a link I could not find on this http://service.dlink.co.in/
my device model and other information I typed msinfo32 command here is relevant screenshot for your help

As far as I know, this has been of the most recurring problem related to networking since Windows 10's early builds...

I would try updating the drivers first, directly from its manufacturer.

Here is a link to the drivers from D-Link:

D-Link Technical Support

Make sure to select the Rev. E adapter.

One other observation:

From your previous screenshot, I see that your DHCP server is 172.16.1.31, but your default gateway is 10.1.0.1. Is this correct?

I have got the same problem in that wifi or ethernet connection will either connect and then drop and connect again or will not connect at all until I intervene and tell windows to start the connection . I have worked through dozens of 'fixes' and nothing provides a solution , however I have read that this is yet another of the problems created by windows update I think 1903 , I found this whilst reading about the problems on file explorer and search caused by windows update . Can't remeber the last time we had a windows major update that actually worked without causing something to break !
