The company's broadband has been intermittent during this period, scolding Netcom for bad broadband. Because it was unclear whether it was the reason for the arrears or what, they did not call Netcom.

Today, Netcom came to us to inquire about broadband usage. Ask me if I am intermittent? It's really strange. How could he know before he even called?

It turned out that the entire building had such problems. He's canvassing every house. I don't know if I don't check, and I'll be shocked if I check. Turns out it was really the problem here.

Because a broadband router is used, although WAN port sharing is not used, HUB is still plugged in for transit. I don't know when, the router's gateway was changed from 192.168.16.1 to 192.168.1.1.

Our entire building uses optical fiber Internet access, fixed IP, and all users are parsed through 192.168.1.1.

As a result, everything was resolved to the company's route.

If we can go on, the entire building can go online. If we can't go up, the whole building will shut down.

Netcom's technicians should laugh and cry: Alas! It's been a whole day!
