Why can t I connect to the Internet with broadband at home, why can t I connect to broadband at home

Error 678 I've encountered,If your account password is correct,You look at the link light on the cat is always on or flashing,Generally, it will flash for a while after turning on,It means that it is connected to the remote broadband service,Not flashing is connected to the road or the server over there is faulty,Generally speaking, it's the server there,Maybe it's in maintenance or something。 Another possibility is that there is an extension on your ** line, but the connection is incorrect, resulting in a drop in the line. Generally, the fault of 678 needs to be solved by customer service.

The line thing, mine too, change the line for a long time, sometimes basically can't go online, Netcom is also to change the connector or something, just replace it.

If you are unable to connect to the broadband issue, you can do the following:

1. Perform stand-alone dial-up, if you use a router, please temporarily disconnect the router for testing

2. Check whether the network cable or ** cable is loose;

3. Check whether the network devices such as modem are overheated, and try again after restarting

4. It is recommended that you perform a full virus scan on your computer.

If your broadband Internet display "error 678", it is due to modem damage, network cable, network card poor contact, **line obstruction and other reasons, if there is a router, it is recommended that you can first power off and restart, if it is still not available, it is recommended that you remove the router and check whether the modem signal light is normal:

1. If it is normal, please try to restart the network card, unplug the network cable, and restart the modem

2. If it is not normal, please try to unplug the ** cable, restart the modem, check whether the splitter is connected correctly and unplug the above cable.

Maybe it's because your road oiler is broken. So is my family. Maybe it's because of a problem with your home's wiring.

It's the problem of the company that is networked, just hit a **.

Error 678 is that the remote control is not on.

Just wait.

It doesn't always work. But it's okay to try.

Try 1: Restart the cat (power off for 5 minutes).

2. Disable local connection.

3. Then re-enable the local connection.

4. See if the light on the cat is normal.

5. There is also the reinstallation of the network card driver.

6. Is there a broadband arrears?

Trick: Call ** to 10000 and let them come and take a look!

The biggest possibility is that the distance between the telecom terminal and your home is more than 3 kilometers, and the broadband signal may not be reached. What I mean by this is that the ** line from the telecommunications bureau is more than 3 kilometers to your house.

You see if the cat's indicator light is normal, generally two green and two orange, the orange-green flash in the middle, if not, it is recommended that you go to the Netcom company to change the cat! Thanks for adopting!

Why can't I connect, are there any tips? Be clear.

Stupid to death you, 1, see if you owe money, 2, see if your cat is bad, 3, look at your character.
