Why does my Kart Racing keep disconnecting?

We use Category 5 cables or Hubble, or ADSL or optical fiber transmission, network switches, routers, etc. to access the Internet. You may encounter: slow computer access to the Internet (stuck, inability to connect to the Internet, poor signal) , instability, packet loss, high bit error rate, failure to connect, crashes, unexplained interruptions, etc., etc., everyone has a headache; among the 42 countries involved in the study, Japan has the highest upload speed. Scores were highest on the time lag research item. Followed closely by Sweden and the Netherlands.

The so-called broadband quality score is based on upload and download speeds and latency. Network speed, server quality and the quality of netizens' home computers will all affect the stability of the computer system and a good user working environment interface. Therefore, users must do the following, otherwise, it will affect your use: < /p>

1: Environmental conditions:

A: Stable power supply voltage (install auxiliary UPS power supply if necessary), effective and safe power cord cross-section; and comply with relevant insulation regulations for safe electricity use ; Mostly the low voltage is caused by the smaller wire diameter of the user. After the transformation of two networks (urban network and rural network) across the country, through monitoring of users (including remote mountainous areas): the user voltage qualification rate is 99.98%, and the voltage entering users meets the national legal value. The power grid uses a variety of voltage adjustment methods at any time to ensure that the voltage is qualified.

B: Suitable drying and ventilation temperature (install a fan or air conditioning system if necessary),

C: Smaller dust particles, it is best to paint the walls and roof Paint treatment.

D: . Appropriate signal-to-noise ratio for the transmission line: (ADSL) user line noise level should be as small as possible to avoid interference clutter, so that the equipment can be reliable at a smaller level. Work.

E: Network card problem: Choose a better quality network card.

F: System software configuration: Users do not need to set an IP address, the system will automatically assign it. If you set DNS, be sure to set it correctly. The operating system is WIN98 or ME. In the DOS window, type WINIPCFG to obtain the DNS region. For WINXP system, type IPCONFIG.

G: TCP/IP protocol: If users find that browsing is abnormal, they can try deleting the TCP/IP protocol and then re-adding the TCP/IP protocol.

H: Influence of humidity: In rainy seasons or rainy days and in high-humidity areas, due to the larger conductance, the conductivity between lines is enhanced, signal leakage increases, and signal attenuation also increases. The reduction of insulation and the increase of the probability of line grounding will cause the ADSL user signal level to drop, resulting in disconnection or unstable operation. Humidity will also accelerate the oxidation of the contact surface. Repeated oxidation will increase the contact resistance. The increase in contact resistance will cause transmission interruption.

I: Impact of temperature: Users who use "cat" ADSL, routers, Hubble, network switches, etc. to access the Internet: Especially in summer, the ambient temperature is higher, and the temperature of the cat also rises. The heating element of Open the cat's box cover and use air convection to strengthen the contact surface with the air for heat dissipation;

i-c: forced heat dissipation: install a micro fan on the cat to increase air convection and force heat dissipation;< /p>

i-d: If you work in IT, I suggest you: After disconnecting the power supply, install heat sinks on the cat’s heating components.

i-e: After the cat is disconnected from the power supply, use a 3 mm drill bit to drill many holes above and below the cat to enhance air circulation and improve heat dissipation conditions;

i-f: After the power is disconnected , open your cat's casing and see if there is too much dust. The accumulation of dust will affect heat dissipation. Remove the dust accumulation.

i-g: Let the ADSL modem be synchronized first: power off the modem and then restart it.

i-h: Cat ADSL MODEM should be placed in a place with small interference sources to avoid abnormal operation caused by interference.

2: Good grounding system: In many computer rooms, the grounding of equipment is unqualified: not many are qualified. Everyone knows that grounding is important, but no one does it, and no one does it personally.

According to the regulations (Code for Construction and Acceptance of Grounding Devices in Electrical Installation Engineering Projects GB50169-92): The grounding must have two or more "independent" (no common "ground") grounding poles, and the cross-section of the lead from the grounding pole to the work site should be Multi-stranded copper wires of not less than 16 square millimeters are not allowed to have any joints in the middle. The ground wires entering the computer room must be "independently" connected to the copper bars. The access point fixing screws should be coated with silver-plated conductive paste and fixed reliably ( A large computer room should have more than four independent grounding electrodes. Welding technology must be used between grounding copper plates, and bolts must not be used to reduce contact resistance. A Faraday grounding cage is used in the computer room, and the cage hole is not larger than 1 square meter to facilitate grounding. Diversion, pressure equalization, shunting). A comprehensive inspection and test of the grounding device shall be carried out at least once a year before a thunderstorm. The grounding resistance of each "independent" grounding electrode shall not be greater than 5 ohms. The shielding layer of user lines and user line numbers (telephone lines or network lines) must be grounded immediately after entering the home to reduce interference to the lowest range. Grounding must be done at multiple points and should not be shared with other grounding electrodes. " "Independent" grounding electrode; the ground of water pipes and electricity (N line) cannot be used as a grounding electrode. The grounding cannot be twisted and must be firmly fixed with screws. During thunder and lightning: Disconnect all connections with the outside world (network cables, telephone lines, power supply, etc.) to avoid equipment and personal accidents and fire accidents.

3: The system is clean and tidy: What makes a person wear clothes does not depend on the grade of the clothes, but on whether they are clean and tidy; therefore:

A: Run the software legally and upgrade security patches in a timely manner; delete Unused files (to improve the running speed of the system), promptly clean up the garbage generated by the Internet, regularly defragment, and optimize the system structure;

B: Legal and effective anti-virus software, and frequently automatically upgrade the virus database; Firewalls, free Internet access software, network acceleration software, etc. should be set properly. Improper settings will also affect user use.

C: Do not put non-running software and other files into the running disk or desktop (to reduce the occupation of the C drive and improve the running speed of the running disk); when you find that some software is disconnected when you open it, you should Close the software immediately and uninstall the software.

D: Strengthen the monitoring and operation maintenance of computer (including auxiliary) equipment at ordinary times, pay attention to the instructions of the operating lights and their alarm signals, do not expand the accident, nip the problem in the bud, and ensure that: the equipment is clean and tidy, Good ventilation, reliable connections, moderate temperature and humidity, excellent insulation, and neat and beautiful wiring.

4: The link is good: Check that the host and various auxiliary devices (keyboard, mouse, speakers, (Category 5 cable) network cable R45 connector, power cord, etc.) must be in good contact. Check the connectors and telephone numbers of the home lines. Check whether the wire plugs, etc. are in reliable contact to reduce machine line failures; wiring: balanced and vertical, clear and neat (avoid entanglement).

5: Reception level under harsh conditions (wireless network card is the receiving field strength, optical transceiver is the light receiving level): signal attenuation is affected by weather, temperature, humidity, distance, and variable interference during transmission. Affected by other factors, especially the changeable interference during transmission is very complex and unstable; therefore, appropriate reception level is very important. When serious interference occurs on the line and the signal noise is relatively bad, the operator should also ensure that the computer receives up and down Under the condition that the line error rate (LAN can reach 1/1000000000---1/100000000000) should not be greater than 1/1000000, the upper and lower limits of the receiving level (because the receiving level is too low, the bit error rate will also increase; the receiving level If the level is too high, the bit error rate will also increase) within the range; instead of only requiring a certain number of MB of bandwidth as some users often say; this indicator needs to be tested in both directions, and the two-way test of this project must be carried out between the computer room and the user, and it must be qualified. It can ensure you a good operating environment. Users have the right to ask the operator to use a "bit error meter" and a "level meter" at your user end to test whether these two indicators are qualified. On the premise of ensuring the bit error rate, the upper and lower limits of the receiving level shall be higher than The level that is half of the middle value and the upper limit level, (for example: the lower limit receiving level is 0dB, the upper limit receiving level is 100 dB, the actual receiving level should be set to no less than 75 dB, the transmitting branch in each direction The amplifier and the attenuator of the receiving branch are adjusted together) as your receiving level, so that your uplink and downlink will have a reasonable signal-to-noise ratio; if the indicators in these two directions are adjusted to meet the standards, the equipment settings are correct and the link is good That's right, there is absolutely no problem with your computer's upstream and downstream circuits.

6: The isolation between the computer and the phone (referring to ADSL users):

6-1: The computer goes offline when ringing: it is the isolation of the computer from the ringing signal (should be greater than 60 dB) is not enough, it is a computer (strong power intrusion) problem);

6-2: The computer dropped when picking up the phone: it is the voice loop of the phone that affects the computer signal (the shunt attenuation is not greater than 1 dB) absorption, causing the computer to drop offline, which is a problem with the phone;

6-3: The computer dropped when hanging up (standby): it is the ringing loop of the phone that affects the computer signal (the shunt attenuation is not enough) Greater than 1 dB) absorption is a problem with the phone.

7: Reminder: In theory: it is very slim to use software to improve your network speed. In fact, you can’t feel it. It is usually a tool for adding advertisements. Using other measures, you can only clear some garbage and debris in your computer on your terminal, and optimize your equipment, thereby improving the processing speed of your terminal a little bit; as long as you do the above eight aspects well, you Not only can current faults be eliminated; in the future, some inexplicable faults will not occur.
