Network Connections has totally disappeared

[Dougbert]

Starting at the first reboot after my last Windows update, I lost the ability to connect to any and all network connections on my PC. I can boot into Windows like normal, and everything except the network and internet works. Every option on my WinX menu works except Network Connections.

When I click on Network Connections from the WinX menu, I get the following error message:
Settings: SystemSettings.exe – system error
“The system detected an overrun of a stack-based buffer in this application. This overrun could potentially allow a malicious user to gain control of this application.”

First, I don't know which application the error message is referring to, and second, I don't know what to do next. Any suggestions or experience with this error would be greatly appreciated! Thank you!

If your system is like mine. You will need to install updated network drivers.

Do you know which networking adapter you are using? Is it Realtek or something else?

 

[Dougbert]

It is Realtek. Do I need to reinstall that? I know how to delete drivers through device manager, but how do I know exactly which drivers to delete/reinstall/update? Thanks for responding to mu question!

Are you using a third party anti virus program.
Also, a very easy first step, which has been known to be succesful, is to run the built in troubleshooter. .
Settings - Network and internet - and Network Troublesshooter

 

[clifford_cooley]

Try Dave's suggestion with the troubleshooter first. If that doesn't help download an updated driver from Realtek.

I can't run that troubleshooter because I have no access to the Network and Internet setting. That is when I get the stack overflow error message.

.
? I don’ get that one!
youshould be able to open the settings. Just to try, I disabled my internet connection, but was still able to get into the settings, including the internet section. But why the Winx route

Right click the start button, from the context menu choose "Run"
In the Run dialog box type cmd
Hold the control and shift key and strike the enter key
Answer in the affirmative when you receive the UAC prompt.

In the administrative command prompt window type
netsh int ip reset resetlog.txt
hit enter
then type
netsh Winsock reset
hit enter
then type
exit
hit enter
Restart your computer
See if that works for you.

Thank you! Unfortunately, I continue to get the same buffer overrun message.

There are three listings under network adapters, so here are their hardware id's in order:

Are you depending on a physical ethernet connection via a Cat5 cable from your router to your computer
OR
Are you using a wireless connection?

 

[Dougbert]

physical cable

Ethernet Controller https://www.realtek.com/en/componen...0-1000m-gigabit-ethernet-pci-express-software

Keep in mind that if this is a laptop then it is often better to install the drivers provided by the manufacturer for that specific laptop, as in some cases they may have been modified so as to work with other physical hardware components within that laptop (bridges and buses).

I always instruct my Clients/friends keep the Original DVD-CD-USB files on hand due to such issues.
insert the DVD-CD-USB and reinstall the Original OEM Drivers.

Sadly MS updates are breaking those old original drivers.

 

[Snuffy]

yes, but then Dell, HP, Acer also updates and breaks the old drivers.
