Welcome to this forum!
Could you please tell us a bit more, what you tell us now is not enough:
- internet land wire: do you mean that you have connected your PC by a lan cable to internet?
- we need also the specs of your computer!
- If you are using a lan cable, have you tried a different computer on the same connector?
- has it been ok before? Or was it the first time that you connected the computer to internet?
- Have you tried connecting your computer to a different wall lan connector or using WiFi?
Hope to hear soon of you
