Hello, this is my first thread.

I have a PC which is connected to internet through ethernet cable.
Everytime i turn on my PC it says ethernet cable unplugged.

So, one thing that works is: I have to unplug the UPS power cord for 2, 3 seconds and, tadaaa!!! internet is up.
If i shut down PC at night and turn it on in the morning, the problem still appears.

Things i tried to eleminate the problem: Changed ethernet cable, Changed extension cord (Thought of any electrical interference of extension cord cable in ethernet cable), but the problem still persists.

Has anyone had this type of problem?

Thank you.

The Network adapter power saving mode is disabled.
The cable length is about 15 - 20 meters.

I have 10 other PCs in LAN and this pc only has the problem.

Change you network port of the switch and check.If problem continues plug the network cable to anther computer and check the new computer's internet connection. If it connects to the internet. Your computer network card is faulty.
