How do you know a network switch is failing if the link lights are lit. The server is not able to connect to the internet if the modem is connected to the switch and the server is connected to the same switch.
...But if I connect the server directly to a port on the modem, the server is then able to access the internet.
OR could it be a bunch of bad network cables
OR could it be an electrical issue, because we had a power surge, the night before the internet went down.
