If you change the router password and remove everyone from the Wi-Fi, the problem will be solved.

Hello, if even with that your problem is not solved it can be network cable failure. I had to try another network cable and it worked. On another occasion it didn't work that way and the problem was the network card jack that was failing. To do this they sell some pci network cards that incorporate them into the cpu. Once that network card is detected, try to connect the network cable there. In case it worked. That is to say that the connector of the network card that comes included did not work properly so I had to buy an additional one and with that it was solved. In the first opportunity and it was with another PC, the problem was the network cable that was badly struck. Change all the cable and connectors and it worked. Let's see if this helps them.

I didn't quite understand what you are trying to ask. Can you explain yourself in detail? Regards.

You must explain yourself in detail because if you should not consult a fortune teller. What type of IP assignment do you have (manual or DHCP)? What operating system do you use? How is your network (Switch, Router, Moden / Router, Wifi, PC, etc) and how many devices are connected at the same time?
