Windows 10: Wifi connection keeps disconnecting frequently on my Windows 11 laptop

Internet connection on my Lenovo s540 - Windows 11 laptop keeps disconnecting frequently. I initially thought that it could be an ISP issue and engaged them.Later, I noticed that the wifi itself disconnects every few minutes, randomly, throughout the day and exactly every day at 3 AM IST for few seconds and reconnects automatically.In the event logs I noticed this below error and it coincides with the disconnects.

Lan disconnects frequently on wifi router

I have a wifi router setup,
internet on my laptop works fine which is connected on wireless
but my pc which is connected through lan with wifi router get disconnected after some time, and to make it work I have to disable and then enable it.

Please help regarding this issue.

 

Wireless connection for my laptop disconnects

You need to distinguish whether its the router or the laptop before you can solve the issue. You can not just guess otherwise it makes it difficult for us to help you solve the issue. In the task bar it has the signal strength bar in green, is the bar still active when the connection drops? If it is still active after disconnecting then the router is doing its job and its something else.

Then its most likely a software issue, i.e. bad OS configuration or WIFI configuration. Otherwise if it was a hardware (router) issue it would disconnect on both MAC OS X and Windows.

Provide screenshots of your settings and configurations for the WIFI card.

 

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
