How to maintain the local area network (LAN)

In the LAN, the Internet is often disconnected, causing headaches. The computer system is stable and the lan network speed is fast. A good user working environment interface is required, in this way, the Internet access speed in the LAN is guaranteed.

 
 
I. Environment Conditions
 
 
A: stable power supply voltage (Auxiliary UPS power supply is installed when necessary), effective and safe power line section; and complies with the relevant Insulation Regulations for safe use of electricity
 
 
B: suitable dry and ventilated temperature (if necessary, a fan or air conditioning system is installed)
 
 
C: smaller dust granularity. It is best to paint the walls and their roofs.
Ii. Clean the system
People wear clothes not in their grades, but in whether they are clean and tidy;
A: legally run software, promptly upgrade security patches, and delete unnecessary files (to speed up system operation ), clean up the garbage generated by the Internet in a timely manner, organize fragments on a regular basis, and optimize the system structure.
 
 
B: valid anti-virus software, and regular updates to the virus database;
C: Do not place non-running software or other files on the running disk (to reduce disk C usage and increase the running speed of the running disk)
 
 
D: clean equipment, good ventilation, reliable connection, moderate temperature and humidity, excellent insulation, and neat and beautiful wiring.
3. Good link
Check that the host and each auxiliary (keyboard, mouse, speaker, (five-class line) network line R45 connector, power cord, etc.) must be in good contact with each other to reduce line faults; wiring: vertical, clear and tidy (avoid tangle ).
Iv. Ventilation and Heat Dissipation
 
 
Users who use "cat" ADSL, routers, harbo, and network switches to access the Internet: especially in summer, the ambient temperature is high, the temperature of the CAT also rises, and the heating elements in the cat become hotter; therefore, we recommend that you:
 
 
A: place the cat in A ventilated and dry place for natural heat dissipation.
 
 
B: To keep the cat safe, open the lid of the cat and use air convection to strengthen the contact surface with the air for heat dissipation.
C: forced heat dissipation: Add a micro-fan to the cat to increase air convection and implement forced heat dissipation;
 
 
D: If you do IT, disconnect the power and install a heat sink for the cat's heating components.
E: after the power supply is disconnected, the cat uses 3mm of the drill bit to drill a lot of holes in the cat up and down to enhance air circulation and improve heat dissipation conditions.
 
 
F: after a power failure, open the shell of your cat and check whether the accumulation of dust will affect the heat dissipation and clear the accumulation of dust.
5. Reception level under severe conditions
The line attenuation varies by distance, and the appropriate receiving level is very important. When the line suffers severe interference and the signal and noise are large, the operator shall ensure that the computer receives upstream and downstream error rates (the local area network can reach 1/1000000000-1/100000000000). The receiving level ceiling and lower limit should not be greater than 1/1000000 (because the receiving level is too low, the error rate should also increase;
The receiving level is too high, and the error rate is also increased), rather than the number of Mbps required by some users. This indicator requires two-way testing, and two-way testing of the Project is required between the data center and the user, you must be qualified to ensure a good running environment.
 
 
The user has the right to ask the carrier to use the "Incorrect code meter" and "meter" on your client to test whether the two indicators are qualified. While ensuring the error rate, the carrier has the upper and lower limits of the receiving level, take the level above half of the center and upper limit level (for example, the lower limit of the receiving level is 0 dB, and the upper limit of the receiving point is rated as 100 dB. The actual receiving level should be set to no less than 75 dB, the amplifier of each direction sending Branch and the attenuation device of the receiving branch are adjusted together) as your receiving level, so that your upstream and downstream lines have a reasonable signal-to-noise ratio; if the indicators in both directions are properly adjusted, the device settings are correct, and the connection is correct, your computer's upstream and downstream circuits are absolutely no problem.
6. Isolation between computers and phones (ADSL Users)
1: The computer is disconnected when the system is ringing. This is due to the computer's (strong electrical intrusion) problem because the computer's isolation from the system is insufficient (should be greater than 60 dB );
2: when the computer is disconnected: it is the absorption of computer signals (shunt attenuation is not greater than 1 dB) by the voice circuit of the phone, resulting in computer disconnection, which is a telephone problem;
3.
 
 
Reminder:
 
 
Theoretically, using any software to increase your network speed is very slim. You don't need to believe in a simple way, it can increase the network speed, the software can increase the network speed relatively slim, and all Software Acceleration, in fact, you cannot feel it. Generally, it is a tool for adding advertisements. Using other measures, you can only clear some junk in your computer on your terminal, optimize the running environment of your device, and increase the processing speed of your terminal (computer; just as the water pressure in the water plant is low, you are increasing the diameter of your water pipe, and you cannot solve the water pressure problem in your house. You can never improve the network speed! Isn't that just a joke? It's hard to find out if you just want to download software that increases the speed of your network. Otherwise, this software just installs some advertisement plug-ins in your system.
Reasonable maintenance of the LAN environment is good for LAN users.
