Hello!
I turned on my PC today and the internet didn't work.
The cable is connected but it shows on the PC like there is no cable.
- the wifi in working fine on the modem.
-the cable is working fine because I connected other computer with the same cable and modem and it worked .
-when I connect the cable to the computer he doesn't recognize it and there is no green light at the internet port when I connect it.

Tried many things but nothing worked , hope that someone can help me .

Thank you for reading :)
