Yesterday, I upgraded Windows 7 to Windows 10.
Since then, I get disconnected from the internet at random moments. However, it feels like as if I get disconnected when there is a lot of data traffic going on, but I'm not sure. I'm using LAN cable, not Wifi.
When it happens, I can't use the internet anymore and I get that yellow "!" symbol on the network icon on the taskbar.
It doesn't work when I try to fix it automatically by right-clicking on it and a red "x" will appear instead.
I have to restart the PC to make the internet work again.
It never happened before I had Windows 10 installed.
The driver of the network card seems to be already updated to the latest version.
