Broadband failure. First, the fault phenomenon.
In the process of surfing the Internet, users encounter faulty phenomena such as slow Internet speed, disconnection, and web pages that cannot be opened.
2. Failure analysis.
1.User-side failure: Problems such as aging of the user's line, poor contact of the crystal head of the network cable, and short circuit of the network cable will cause the fault of the user.
2.Broadband equipment failure: Broadband equipment failure can also lead to broadband failure.
3.Network congestion: During peak or congested periods, the network bandwidth cannot meet the needs of users, resulting in problems such as slow Internet access speed or disconnection.
4.Line interference: Broadband lines are interfered with by external signals, such as mobile phone signals and other communication lines, which can lead to problems such as slower or dropped Internet access.
5.Carrier failure: Broadband failures can also occur due to problems such as equipment failures or network outages from carriers.
3. Troubleshooting process.
1.User repair: The user calls the operator's service** to report the broadband fault.
2.Fault dispatch: The carrier's customer service staff dispatches broadband fault orders to maintenance personnel.
3.Fault location: maintenance personnel locate according to the fault phenomenon and determine the cause of the fault.
4.Repair faults: Repair faults based on the cause of the fault, such as replacing lines, devices, and debugging networks.
5.Receipt confirmation: After the maintenance personnel complete the repair, they will confirm the receipt to the customer service personnel, and inform the user that the fault has been repaired.
6.User verification: The user verifies whether the broadband has returned to normal, and can report for repair again if there is a problem.
4. Preventive measures.
1.Regularly check whether the network cable, crystal head and other line connection equipment are aging or have poor contact.
2.Try to avoid surfing the Internet during peak hours or network congestion.
3.Pay attention to protect the line to avoid interference caused by external signals.
4.Back up important data regularly to avoid data loss due to device failure.
