Why is the internet speed poor on cloudy days and good on sunny days?

Because of the wet weather, the loop of the communication line is wet. In this case, the home phone can be dialed smoothly, but the call will be automatically disconnected. At this time, the broadband network speed is not as good as before. If you pay a little attention, you can find that the signal light in the middle of the switch is flashing. This situation will get better when the weather becomes dry.
