Why does my DNF always lose its network connection?

Because G was turned on in your computer, TX still found some abnormal data in your computer, or you were taken away by G, which led TX to think that you were disconnected because you turned on your mobile phone. The latter is easy to solve, as long as you wait 1 hour, you can re-enter. The former is a bit tricky. Use antivirus software. If it doesn't work, reinstall. It is recommended not to use the home computer to open G, which is very dangerous and has too many problems. .
