Broadband connection error 678 detection and solution

For a series of problems that will occur in dial-up broadband Internet access, Xiaobian has compiled some reasons for the error link analysis and solutions. The following describes the processing flow of broadband connection error 678 (remote computer does not respond), I hope to be useful to everyone. Step 1: Check if the MODEM signal is normal, and restart the modem abnormally. If you see step two, see normal. Step 2: Ask the user whether there is a firewall or 3721 Internet Assistant and other software. If yes, it is recommended that the user exit (1) Firewall and 3721 Internet Assistant test: If the fault is resolved, the cause of the failure is “User Software Problem” (2) If the fault persists, proceed to the next step to continue processing. Step 3: Instruct the user to check the status of the NIC and plug in the network cable: (1) If the fault is resolved, fill in: the cause of the fault is “pc hardware problem” (2) if If the fault persists, proceed to the next step to continue processing. Step 4: When the condition is met (the user has dial-up software, installation CD (Win98 must have a network card driver), it is recommended that the user delete the dial-up software and then re-install the NIC driver and install it. Dial-up software: (1) If the fault is resolved, fill in: the fault phenomenon is “Dial-up connection timeout”, the cause of the fault is “PC hardware problem”; (2) If the fault persists, proceed to step 7 to continue processing; Step 5: Determine whether the telephone line behind the MODEM is available, and whether the splitter connection is correct: (1) Connected to the MODEM Words cannot be used, and other telephones with billing numbers can be used. It is recommended to replace the telephone line. The reason for the failure is “User indoor line failure”; (2) If all the telephone numbers of the user's home bill are not available, Please call customer service 10000 Telecom (10060 Netcom/10050 Railcom) to report the obstacle. Step 6: If the above processing is invalid or the user can't do simple operation, please call customer service 10000 Telecom (10060 Netcom/10050 Railcom) Obstacle complaint.
