Windows 10: Wifi keeps disconnecting after windows 10 reboot

Hello,


I upgraded my laptop Lenovo Yoga 13" by adding an extra SSD. And making a dualboot for windows10 and Linux Mint.
My wifi is working perfectly on the Linux part. However on the windows part it keeps crashing.

It says that wifi is not connected and when I trouble shoot it says: default gateway not available.

This happens in between once every 2 minutes and every half an hour.



What I already tried:

- Reset TCP/IP

- Reinstall network driver realtek rtl8723be is my network card

- Change power options for network driver

- Reset Network

-change wireless mode to 802.11g



Help!

:)

 

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)

 

Laptop disconnects from Wifi at random intervals

Thanks for the suggestion, both of those settings are already turned off.

 

Windows keeps disconnecting from wifi


I have Windows 10. Installed about two weeks ago. For the last two days, Windows disconnects me from wifi and often won't reconnect without reboots of router and laptop. I know the wifi is working fine because I get wifi easily and maintain wifi on iPad and smartphone. Is this a new Windows 10 problem? Solution ideas welcome.
