Recently, with the popularity of remote working and online education, network connection issues have become the focus of heated discussions across the Internet. This article will combine the hot content of the past 10 days to give you a detailed answer to the question "How to plug in the network cable", and provide structured data to help you quickly grasp the key points of the operation.
1. Inventory of popular Internet topics across the Internet (last 10 days)
| Ranking | hot topics | Number of discussions (10,000) | main focus |
|---|---|---|---|
| 1 | Illustration of network cable insertion method | 32.5 | Home network cabling |
| 2 | Loose network cable interface repair | 18.7 | Network connection stability |
| 3 | Gigabit Network Upgrade Guide | 15.2 | Network cable specification selection |
| 4 | Differences between router network cable sockets | 12.9 | WAN/LAN port identification |
| 5 | Network cable crystal head production | 9.4 | DIY network cabling |
2. Standard steps for network cable plugging
1.Confirm network cable type: Currently, the mainstream uses eight-core network cables with RJ-45 interfaces, which are divided into straight-through cables and crossover cables.
2.Identify device interface:
| Device type | Interface ID | Things to note |
|---|---|---|
| router | WAN port (blue) LAN port (yellow) | External network cable to WAN port |
| light cat | Network port 1 (Gigabit) | Prioritize the use of Gigabit ports |
| computer | RJ-45 interface | Note that the dust cover is open |
3.Correct plugging method:
• Turn the metal piece of the crystal head upwards, and when you hear a "click" sound, it means it is firmly inserted.
• The maximum bending radius of the network cable is not less than 4 times the wire diameter
• Avoid running parallel lines with power lines and keep the distance at least 20cm.
3. Solutions to common problems
| Problem phenomenon | Possible reasons | Solution |
|---|---|---|
| The network icon shows a red cross | 1. The network cable is not plugged in tightly 2. Interface damaged | 1. Re-plug 2. Replace the network cable and test |
| Connection speed is only 100Mbps | 1. Use Category 5 cable 2. Poor contact | 1. Replace the Category 5e/Category 6 cable 2. Check the crystal head |
| Frequent disconnections | 1. The network cable is too long 2. Electromagnetic interference | 1. Control within 100 meters 2. Use shielded wire |
4. The latest network technology trends
Based on the technical discussions in the past 10 days, there are three development directions worthy of attention:
1.2.5G/5G Ethernet: New network cable sockets are becoming more popular, requiring the use of Cat6A or above wires
2.PoE++ technology: Transmits up to 90W power through network cable, requires special plug
3.Optical fiber composite network cable: New interface for hybrid transmission of copper cable and optical fiber signals
5. Safety precautions
• Turn off the power of the device before plugging or unplugging the network cable
• Avoid operating external network lines during thunderstorms
• Regularly check the oxidation of the network cable interface
• It is recommended that important equipment use network cable connectors with locks
Through the above structured guide, you should have mastered the correct method of plugging in network cables. If you still have questions, you can refer to the detailed illustrated tutorials in recent popular online forums, or consult a professional network engineer. A good physical connection is the foundation of a high-speed network. Correctly plugging network cables can make your network experience smoother.
