Is the hotel slow on the Internet? The switch is serious, how to solve it? (Look at the question before you answer! ! ! ! ! ! ! ! ! )

Go to the front of the switch, unplug the cable connected to the router and connect it directly to the computer for testing. If there is something wrong with the line, test it with the line tester. If there is nothing wrong with the line, connect the computer directly to the switch to see if it is slow. If it's slow, try changing the switch! ! !
