The wifi of my laptop keeps disconnecting even though the wifi is fast.

My laptop is HP Laptop 14 ep0xxx. When I troubleshoot my wifi it says that "Deafult Gateway Is Not Available." and also sometimes it says "No DHCP is assigned." I always try troubleshooting it and it is coming back but then  it will be gone again a minutes later. When I open my laptop, sometimes all is well, like the wifi is not getting lost. But really, most of the time it keeps getting lost. I also keep turning off my wifi button here in my laptop but, again, it will be lost a minutes late. I am so tired of this. I just want to use it well without any wifi problems already.

Bring up the device manager and

see if stopping it from turning off to save power fixed the problem

You probably have Realtek Wi-Fi

Just look for Wi-Fi network device

Oh yes I have the Realtek Wi-Fi. But there's no "Power Management" thing on my laptop.

There is a discussion of the problem of the missing power management tab here

https://answers.microsoft.com/en-us/windows/forum/all/power-management-tab-is-missing-in-device-mana...5

The discussion recommended a registry change that put the power management tab back in

Make a note of the change so you can undo it if a problem show  up.  Note  that discussion was before windows 11 so possibly it does not apply

First try this driver, it is dated sept 2023
