Unfortunately, since the upgrade to Windows 11, I have had problems with the Ethernet controller. I keep getting lags, sound dropouts, whole system lags and high latency. This is annoying in daily use and also restricts conversations.
As you can see in the screenshot, the ndis.sys driver with the Ethernet Controller I225-V has a high latency. This always occurs when the problems described above occur.
Please help me.
What I have already done:
- Uninstalled the driver via the Device Manager
- Driver reinstalled via: Intel Ethernet Adapter Complete Driver Pack
- I have the feeling that the old driver is always automatically reinstalled.
It almost looks like Norton is the culprit. I don't believe it. I have just read by chance that AV programmes can cause such "bottlenecks".
I have now uninstalled Norton as a test and no more high latency for almost 10 minutes. Actually these breaks came in almost every minute.
I will observe this during the day and then report back here.

I suspect that in my case it was the AV protection from Norton. I haven't had any problems since I uninstalled it. We have often heard that AV programmes can create a wrong neck and sometimes overshoot the mark with their restrictions.
