6M ADSL can't guarantee that it will always be 6 m. It depends on how far the node you want to visit is and how many people are visiting it.

If the card can't even open the webpage, check it in two parts. First, check whether it's the telecom itself or our own side. First, check for yourself. See if the computer is poisoned. Is it because many people use ADSL? Is it because ADSL cat hasn't turned off the power for a long time? If it's all right here, call the person at 10000 to check if there is a line problem.

I hope I can help you.
