Why does Jiaxing Telecom drop lines like this?

Whether you use any form of Internet access, you may encounter: slow Internet access (can not browse the Web, card, can not get on the network, poor signal, signal delay, connection failure, instability, packet loss, high bit error rate, on the not go, dropped, dead, interrupted for no reason.) Such phenomena; computer operation is stable, must have the following conditions: A: the necessary environmental conditions: A: stable power supply voltage (if necessary, add auxiliary UPS power supply), effective power line cross-section; in line with the provisions of the safety insulation level. B: dry and ventilated at a suitable temperature (if necessary, add a fan or air conditioning system), C: smaller dust particles, the walls and their roofs should be painted. D: . Appropriate signal-to-noise ratio of the transmission line. E: Network card problem: choose a better quality network card. F: Software settings: Use the software legally; users do not need to set the IP address, the system will be automatically assigned. If you set DNS, set it correctly. System is WIN98 or ME, under DOS, type WINIPCFG to get DNS territory; WINXP system, type IPCONFIG. software settings should be reasonable: ADSL users appear to local connection restrictions or no connection, there will be a prompt, on the Internet does not affect the ADSL users are dial-up and automatically automatically assigned IP, do not want it to appear, you can: Right-click on Network Neighborhood-Properties-Local Connection-Properties-Double-click on Internet Protocol (TCP/IP)-Use the following IP address: IP Address: 192.168.1.120 Subnet Mask: 255.255.255.0 Gateway: 192.168.1.1 Click OK to finish. G: TCP/IP protocol: Browsing is not normal, try to delete TCP/IP protocol and then re-add TCP/IP protocol. H: The effect of humidity: rainy season or rainy days and its high humidity areas, the insulation of the line is reduced, the signal level falls, resulting in dropped or unstable work. Humidity accelerates oxidation, leading to transmission interruption. I:The effect of temperature: low temperature in winter, the cat has fewer problems; high temperature in summer, the "cat" is afraid of "fever". J: After the opening of the network, all the original technical data: so that when the failure of comparative analysis, conducive to fault judgment and positioning. Second: a good grounding system: according to the regulations (grounding device construction GB50169-92) requirements: grounding must have more than two "independent" (can not be communal "ground") of the grounding electrode, grounding electrode to the location of the lead cross-section of not less than 16 Square millimeters of multi-stranded copper wire, each "independent" grounding pole grounding resistance shall not be greater than 5 ohms. User line shielding layer immediately grounded, the interference will be reduced to a minimum; water pipes and electricity (N line) ground can not be used as a grounding pole, the grounding wire can not be twisted, to be coated with silver powder conductive paste, with screws fastened. Lightning: to disconnect all lines connected to the outside world, to avoid equipment personal accidents, so as to avoid fire accidents. Third: the system is clean and sharp: people wear clothes does not lie in the grade of the clothes, but whether it is clean and tidy; therefore: A: legitimate software, upgrade patches in a timely manner; delete unused files, timely cleanup of Internet garbage and regular defragmentation, optimization of the system structure; B: legitimate and effective antivirus software, often upgrade the virus database; firewall, **** enjoy Internet software, network acceleration software, etc., set up a reasonable, improper settings The same will affect the user's use. C: non-running software and other files should not be put into the running disk or desktop; open some software on the phenomenon of dropping, uninstall the software. D: usually on the computer (including auxiliary) equipment to strengthen the monitoring operation and maintenance, to do: equipment, clean, well-ventilated, connected to the contact resistance as small as possible, moderate temperature and humidity, excellent insulation, wiring neat and beautiful. Fourth: good links: check the host and the auxiliary keyboard, mouse, speakers, (Category 5 line) network cable R45 connector, grounding wire, power supply multi-plug, power cord and so on must be (contact resistance in the Ω) good, check the household line connectors, telephone line plugs and so on whether the contact (Ω) is reliable, in order to reduce the failure of the machine line; cabling: vertical and horizontal, clear and neat (not entangled). V: the reception level under poor conditions (wireless network card is: receiving field strength, optical transmitter is: receiving optical power level). Wireless users: As the user terminal is at a different distance from the base station, the receiving field strength level is not the same; therefore, the terminal AGC and base station AGC is particularly important. The computer of the user terminal should cooperate with the AGC of the operator's equipment, so as to meet the useful signals that can be reliably received by the computer under different field strengths (with higher signal-to-noise ratio). Six: the greater the better out-of-band isolation, the smaller the better in-band attenuation: xDSL, broadband, wireless, fiber optic and other users, are to provide the smallest in-band attenuation (less than 1dB), out-of-band isolation (greater than 60dB or more). The signal-to-noise ratio should also be greater than 60dB or more. Seven: the above mentioned aspects, all must do it yourself, and record the data as information. For example, you use ADSL Internet access: modulator transmission level is how much? What is the entrance signal-to-noise ratio of the demodulator? What is the input entry level of the demodulator? What is the grounding resistance of your equipment? Are the connections making good contact? How good is it (what is the contact resistance)? Have the above information, the party can ask me to add questions for me to answer; no information, I do not answer anyone to add questions; to speak with data, data can help you quickly determine, analyze, locate the fault. Eight: Reminder: Theoretically: the use of software to improve your network speed is very slim, in fact, you can not feel it, generally add advertising tools. The use of other measures can only be on your terminal to clear your computer inside some of the garbage, debris, optimize your equipment, thereby improving a little bit of your terminal processing speed; as long as you do a good job in the above seven areas of work, you can not only eliminate the failure of the hardware equipment; the future will not be produced by the failure of the hardware.
