When it rains, the internet speed will be fine. What happened to the card?

Rainy days are prone to problems. Generally speaking, the main problem of this situation is the line, not the real line water, largely because the line is affected by moisture, which affects the broadband signal. The general solution is to connect broadband from bus, which can fundamentally solve this problem. Also, find out which part of the thread is wet and replace this thread. Especially the connection of the line, it is best to wrap it with waterproof self-adhesive tape. Otherwise, it will get wet easily if it rains on cloudy days.
