Solved Why WiFi disconnect in win 7 after 5 minutes

[Vertex]

Try this:

1.Right click Network and Sharing Center on the Taskbar.
2. Go to Change Adapter Settings on the left hand side panel.
3. Right click the Wifi adapter you use, then Properties the Configure. While on the General tab, see if it says this device is working properly.
4. Go to the Advanced tab. Here you will see the hidden features of your wireless adapter. These features are not the same for different wireless adapters so my wireless adapter will have different or some similar features with yours. See if any of the settings there says anything about "auto disconnect" or "power saving" then disable that. I personally have the "AP Compatibility Mode" feature which the default was "higher performance" which I changed to "broader compatibility". I believe it improved the connection. When I first had my Wifi MODEM, it had trouble connecting with my wireless adapter until I changed some of the settings listed here. I got it right somewhat by chance that I was able to connect. You might have to manually change your settings here and see if anything works for you. It restarts your wireless adapter every time you apply changes.

5. If nothing else works, you might consider installing a new driver for your wireless adapter. An easy way for that is simply go to the Driver tab next to the Advanced tab. Under the Driver tab, click the Update Driver button.

Did you take a look at the bandwidth issue in that link?

@w2
Bandwidth issue seems not to be a problem.
Because all devices working properly
With no speed issue.
And for 5 minutes of laptop working Wifii
It has expected speed, which is very good.
The problem is disconnection after some minutes.
And I find no hidden settings.
I think the hidden settings are in insyde BIOS.

The bandwidth issue in the link identifies that the problem can occur when you have multiple devices connected at the same time.

The answer is NO!
Because in my home I had the same multiple devices
And the same laptop, and wifi was working then.
But don't know what is the problem now.
And I uninstalled and reinstalled drivers and rollbacked drivers but the problem remains.

Are you sure you followed the steps? The hidden settings of your particular Wifi adapter should be accessible through Windows. Even on a Windows 10 laptop, I was able to access this.

You should be able to see this panel of settings for your WiFi adpater.

The problem.

I know this is a bit off the wall but, go to Accessories, System Tools. Run the Disk Cleanup utility. When it says how much space it can free up, check the boxes for Temporary Files and Recycle Bin. When it's done, reboot. Does that help?

 

[qpod25]

I did that but the problem remains
Unsolved.
