There are a lot of reasons for this situation:
1: First, you double-check the cable and the crystal (R45) header: Is the crystal header plugged in with the seat (loosened?)? Is the contact good? What is the contact resistance? Is there any accumulation of dust? Is it oxidized? Is the mechanical lock between the crystal head and the holder locked? Is the latch secure? Are the network cable and the crystal head pressed together and in good contact? The insulation resistance of the network cable (using a 100V rocking meter) should be greater than 20 megohms.
If it doesn't work, you shouldn't be angry! There is no cow that suffocates, only a fool who dies; ........................ ..........
3: If it does not work again: take a look at the following method, you may wish to use the measures you feel acceptable method, your love machine to do a thorough sorting out, you will not happen this kind of phenomenon. Is the contact good? Are the plug-ins loose? Are the plug-ins tight? The device should be cleaned of dust and dirt.
B: due to equipment overvoltage, low voltage, voltage fluctuation is too large, overcurrent, heat, resulting in overheating protection action to cut out the fault and the equipment out of operation (i.e.: slow, delayed, repeated startups, delays, dropouts, interruptions, disconnections, automatic shutdowns, deadlines and other manifestations) and so on;
★★★☆☆◆▼▲●●■This answer belongs to the " Correct judgment, it will produce packet loss, serious packet loss is the reason for the delay, serious delay will be the dropout (will produce slow, delay, repeat start, dropout, delay, dropout, interruptions, disconnection, automatic shutdown, shutdown, and other manifestations, etc.), the use of murmur meter or level meter to measure the murmur level is in the permissible range, or with an oscilloscope to observe the presence of spurious signals? Is there any inter-code interference between codes? Take measures to eliminate it.
You can also take the following measures to deal with, and do a good job of grounding the equipment shielding, a lot of interference from poor shielding and poor grounding, causing the computer slow, packet loss, repeated startup, delay, dropouts, interruptions, disconnections, automatic shutdowns, crashes, and other manifestations such as. Preamplifier circuit saturation or burnt preamplifier circuit. Therefore, receiving level adjustment is very important. Use a level meter or oscilloscope to adjust the receive level of the connection in the appropriate amplitude range.

Three: impedance matching: the connection point must be done to match the impedance relative to each other, the input and output impedance mismatch will lead to reflective attenuation, and the signal is strong enough not to work properly.
1: Place the device in a safer place for people, first disconnect the power supply, and then open the box cover of the device, the use of air convection to strengthen the contact with the air, natural heat dissipation;
★★★☆◆▼▲●■This answer belongs to the "There are still ?ェイパーチュウ ╮" individual, copying can be shameful ★★★☆◆▼▲●■
2: Add a new device to the device.
2: Add a miniature fan to the device to increase the convection of air for forced heat dissipation;
3: If you are in IT, I suggest that you: after disconnecting the power supply, add a heat sink to the heated parts of the device.
4: After the equipment is disconnected from the power supply, use a 3-millimeter drill bit to drill more holes in the top and bottom of the equipment to strengthen the air convection and improve the heat dissipation conditions;

5: The equipment is to be used in a dry and ventilated place, it is best to do a heat sink. To prevent this, simply reapply the silicone coating and return to normal operation. It will make the space on the C drive smaller and smaller and cluttered, and then gradually slow down until it dies; therefore, regular organization of the C drive can keep the computer running at speed.
D: First, synchronize your ADSL device: power it down and restart it.
E: software settings reasonable, do 3 not installed: informal software is not installed, P2P (resource-hogging) class software is not installed, not commonly used software is not installed. Not cleaning up the table, not cleaning up the dishes, not cleaning up the stove will produce computer garbage, the computer will gradually show up as slow, card, delay, repeat startup, drop and other faults; therefore, I recommend the use of a number of gadgets: such as Super Rabbit, Optimizer, LU Master, or 360, etc.; and get into the habit of cleaning up the garbage before getting off the line.
G: At least one valid and genuine antivirus program: firewalls are set appropriately (not too many, too high); viruses can slow down computers, crash, drop out, get stuck, start up repeatedly, and switch on and off.
H: NIC Issues: NIC bandwidth is appropriate, works stably and dissipates heat well.
Do a good job of grounding, separate routes for strong and weak signals, and separate routes for high and low frequency signals; good shielding and grounding; and when surfing the web, try to avoid the peak of the internet. very satisfied; otherwise: configuration and then high computer will be the same frequent failure; like people wear clothes (skit: good people and bad people in the Chen Pace: you give him even better clothes, he can not get on grade!) The same, clothes are not in high or low grade, clean and sharp is good. No matter how high you are configured, if you do not follow the computer safety maintenance and use methods to use, you will fail constantly, accidents happen frequently. Many failures are man-made, things in people!
