No solution! Your situation is a bit difficult! ! It seems that someone is up to something, but it is not. It is said that 2 trillion 160~200 is normal. The original 400k may be a port problem, but now they find that your speed has dropped, but their internal system will automatically raise your port to 4 megabytes for you after a while (its speed increase is to improve the port of the whole board, not for you personally).

Depends on your situation. In fact, it should be the Unicom port problem.
