Question No network caused by bad network drivers (?)

[stressato]

Hi. I don't really know where to start, but I'll try to say everything I can, if I'm missing something don't hesitate to ask.
So a friend built a new pc with a Ryzen 5 and a B550M DS3H.
Everything went fine till Apex got started, here's when the network stopped working and rebooting the pc didn't work, forcing us to update the drivers.
After that, though, the ncpa.cpl panel (Network Connections folder) got the Realtek Gaming 2.5GbE Family Controller and the Realtek PCIe GbE Family Controller, both of them are disabled and right-click enabling them will disable them after a few seconds automatically.

Update your post to include full system hardware specs and OS information.

What network connections/connectivity are you using?

Any error messages or pop up windows appearing when the network stops working?

Are you enabling two network adapters? Only one network adapter should be enabled.

Run "ipconfig /all" (without quotes) via the Command Prompt and post the results.

You should be able to copy and paste the results without needed to retype everything.

Hi, thanks for the answer.

The OS is Windows 11.

No error message shows up, windows just starts with no internet connection.

We're not trying to enable 2 adapters, even one at a time can't be enabled, it turns off automatically after a second.

I'll post the ipconfig and full system hardware specs soon.

Very good.

Also take a look in Reliability History and Event Viewer for any network related errors.

Reliability History is fairly straight forward and user friendly.

Event Viewer is similar but more difficult to navigate and understand.

No need to rush in either one of them. Just look and get a sense of how it all works and the information being presented.

Both tools provide additional details but the details may or may not be helpful.

Here's the ipconfig

 

[Ralston18]

Check your network adapter's configuration.

ipconfig is showing a subnet mask of 255.255.0.0

Should be 255.255.255.0

Make and model router?

Can I check the adapter configuration if it's disabled?

The router is a Wind one, we're from Italy

Update: the reliability history and event viewer are showing:

• a bunch of unproper shutdowns,
• even more "explorer.exe" stopped working,
• "MoUSO Core Worker Process" stopped working,
• "settings" stopped working,
• windows hardware errors,
• Razer Synapse's GameManagerService stopped working
• "SystemSettings.exe" stopped working,

This router (DGA4130)?

https://www.wind.gr/wind/routers/Technicolor_DGA4130/DMS3-CTC-25-420_v1.0_public.pdf

Look at the router and confirm by model number that I found the correct router.

Router's default IP is 192.168.1.1 per physically numbered Page 20 of the User Guide.

And if there is another known working network computer available on the network you can confirm the network adapter settings via that computer's network adapter's configuration settings.

= = = =

As for all of those errors I generally view varying errors and an increasing number of errors as a sign of a problem PSU.

However, it could also be that one or more connections are not fully and firmly in place. Nobody wants to force anything on a new build so what seems to be fully and firmly in place is not. Loose connections causing intermittent power losses to supported components.

What to do: Start over.

Use the motherboard's User Guide along with the documentation for all other system components to carefully double check that all connections and configuration settings. Some motherboard's, for example, require that the first physical memory module be placed in a specific DIMM slot. Details matter.

Go slowly and carefully. Disconnect and reconnect to ensure full connections.

Just a basic setup - no overclocking, etc.. Objective being to get a working stable system running on the network then make other changes later.

If all appears okay then the next step is to run "sfc /scannow" and "dism" to fix any files corrupted by improper shutdowns.
