ADSL off line eight crime treatment method recruit to deal with internet surfing

ADSL off line involves many problems, including line fault (line interference), ADSL modem fault (fever, quality, compatibility), network card failure (slow speed, outdated driver) and so on. Operators and users should do the following routine inspection: ADSL telephone line connector is safe and reliable: whether away from the power cord and high-power electronic equipment, ADSL household line and separator between the installation of telephone extensions, fax machines, billing equipment, such as: whether the correct installation of the separator; Replace the old ISA network card with 10/ 100M PCI network card and the latest driver, the ADSL modem cooling is good, ADSL modem led status is normal.

　　 the reason and treatment method of ADSL off line are as follows:

　　 (1) grounding wire quality problem.

PC grounding performance must be better. Otherwise, static electricity will affect the transmission rate of ADSL and even cause the drop line. General PC grounding resistance should be less than 10 ω. In addition, due to the construction of the power supply cloth is not standardized, some have no grounding wire, or ground quality is not qualified, will also affect the normal use of network equipment, and even the problem of line drop, should be timely rectification.

　　 (2) The line has a strong interference source.

From the user cable line 100m within the radio transmitter tower, welding machine, tram or high-voltage power transformers, such as strong signal interference sources, so that users receive clutter (copper clad steel wire shielding weak. Strong ability to receive signals, causing strong interference to the user line. The interference signal is often from the screen without shielding to enter, because the relay cable has a shielding layer, interference is very small, if the interference in a large place with a number of shielded off the line, will reduce the rate of interference caused by instability or drop. In addition, the power cable can not be parallel with the ADSL line, in case of crosstalk caused ADSL fault.

　　 (3) The quality of the NIC is not stable.

Fault phenomenon is that the network as long as a disconnect, no longer connected. User modem's DSL light is often bright, the basic troubleshooting line fault, most of the problems in the network card. If you exclude the network cable, computer, slot problems, generally for the quality of the network card is not stable, should be replaced in time network card.

　　 (4) The distance of the subscriber line is far.

Irregular drop line by the quality of the line is poor or far from the distance, you can use ADSL tester test signal attenuation and interference strength, find a better route replacement. General user relay lines should not exceed 5km, the line from the box into the user's room should not be more than 100m.

　　 (5) Can surf the internet, but the phone is off line.

Many reasons for the handover between the terminal plate line card broken, because the disconnection head and terminal plate distance is very close, so the data induction can pass, and voice, such as the user is very close to the end of the bureau, indoor line mixing line can also cause the above fault.

　　 (6) Internet, call does not take into account.

Generally for outside insulation or have joint contact bad. User-side outside the insulation is bad, users surf the internet when a phone handle warning lights flashing, wan lights off, repair outside the fault immediately after the break.

　　 (7) can call, but the internet off the line.

The general user to connect the wrong line of the situation is to connect the modem line on the phone, you will be able to use the phone, and the Internet off line. At this time ADSL modem state lamp Line light does not light. Check the fault should first carefully check the equipment use wiring position, usually as little as possible to avoid the wrong line.

　　 (8) wrong serial telephone extension.

Due to improper serial phone extension, causing crosstalk, causing the Internet data distortion. If you must use a telephone extension, you should string a separator.
