What s wrong with the computer connection error code 678?

It's a broadband connection, and the 678 remote computer doesn't have a response. Try: Whether the sub-interface of the **line is plugged in, one side is plugged in**machine (the letter P begins), and the other side is plugged in the cat (the letter M begins).

If the broadband cable is not plugged in properly or loose, plug it in tightly or unplug it and plug it back in. The cable inserted into the network card is not properly plugged in. The light with the NIC plugged in is green.

It will flash when the network connection is successful. The service of the carrier such as telecom or Netcom expires and you need to pay for it before you can use it. Check whether the network is installed and check whether the network card is broken

Start> Settings > Control Panel > New Network Setup Wizard > Next > This Computer Connects to the Internet Through the Resident's Network" to install. If the network card is bad, the installation cannot be completed if the network cannot be detected.

It depends on whether the error** jumps out in 5 seconds or after more than 10 seconds. Try a few more times, and if it appears after more than ten seconds, you generally don't need to pay attention to it first. Encounter this type of problem.

The first step is to see if the device's indicator light, such as DSL or LINK, is normal. You can also use the R key that comes with the device to restore it! If it still doesn't work, then it might be a problem with the computer.

There are not many general equipment problems! Tip: When your device is booted up, type ipconfig in the command prompt to see how much your network card IP is getting

Or? Or is it?...The device is generally the last one that does not have DHCP capability.

If you get the correct address, it may be a problem with the machine system settings! You can try turning off the firewall of the machine. Now there are motherboards, network cards.

They all come with firewalls. **。

678 is a telecommunications problem. First of all, you see if your broadband bound ** machine is in arrears. If not, then call 10,000 telecom warranty.

678 is a problem with your connection, see if your ** and cat connection is normal. Or maybe there's something wrong with the line!!

1.Error 678: If the remote computer does not respond, it is generally possible that the broadband modem or line cannot be synchronized, or that there is a problem with the equipment in the operator's computer room, or that there is a problem with the computer system

2.Check the status of the broadband cat, there is a DSL or whether the link light is always on (different brands of cats have different English logos), the DSL or Link light on the broadband cat indicates the communication status between your broadband cat and the operator's computer room equipment, it should be always bright at normal times, if it is not bright or shiny, the biggest possibility is that there is a problem with your **line, it is recommended that you directly call the operator's customer service** to report the obstacle for people to check and repair, and it will generally be dealt with in one to two working days.

1. Broadband Internet display "error 678", it is caused by modem damage, poor contact of network cable and network card, ** line obstruction, etc., 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 separator is connected correctly and unplug the above cable.

2. If it cannot be solved, you can contact the local manual customer service for feedback.

First of all, check whether the network card driver of the computer is installed, whether the network card is disabled, and whether the network cable is well connected to the computer.

Make sure your computer is connected to the modem to dial, do not connect to the router and dial the number, otherwise it will definitely be an error.

If all of the above is confirmed to be normal, it is necessary to check the working indicator of the modem

ADSL access: see if the data, DSL, and ADSL lights of ADSL cats are always on? If it's flickering, it's a network problem.

For optical fiber access: check whether the optical signal or LOS lights up red, and whether the network G light flashes, if the red light or flashes is the network problem.

If the indicator light of the modem is abnormal, then you need to contact customer service and let the master come to repair it.

If there is no modem, this problem occurs when the network is directly plugged into the network cable, and it is a problem with the uplink device, and it is directly repaired. Thank you.

Error 678 is one of the faults of broadband. The implication is that the remote computer is unresponsive. To put it simply, the network is not working.

It is recommended that you contact your network operator immediately.

I have also encountered it, and the customer service said that the regional network is poor, and it will be fine in one day.

This is the computer broadband and the remote network can not establish a connection, it is a problem of the broadband network, not the problem of your own computer, you need to call customer service to ask the reason.

What is the broadband connection error 678.

It means that the line is not working or the network has no signal, please check the line, or call 10000, they will help you deal with it for free!

There is no number of dramas, there is no response to the calculation of far away, call **ask customer service, and check if there is a problem with your **line.
