adsl灯亮故障（Adsl light glitches） There are three reasons for this: A: operators (transmission and exchange of network failure) responsibility: operators must guarantee to the users signal quality, bit error rate and signal to noise (bandwidth, transmission rate and signal level, input and output impedance, signal stability, the stability of the input and output impedance) meet the national standards); Specific telephone: telecom 10000 network connect 10060 iron connect 10050 2. Website problems: 1: website server is not stable; 2. The software of the website is not stable; 3: the maintenance quality level of the website is low; Unable to troubleshoot in time; For example, the other websites are good, and one site is particularly bad, which is the problem of the website itself, which has nothing to do with operators and users.

If you have no problem with the above operators, then your users will have their own problems. If you dont have the following problem, you can call the operator and let the operator give you the operators own issues. Copyright notice: this answer is a harmonious original, no one can embezzle! u The reason for this phenomenon and how to deal with it On the premise that users equipment must be set correctly: 1: the power supply 1.1 check whether the power supply is stable with multimeter. 1.2 is ac voltage fluctuation allowed? Is it above 5% of the rated voltage? 1.3 the ripple coefficient after the transformation of A/D (with A millivoltmeter) is it acceptable? Is the temperature rise of the power supply abnormal? 1. Is the voltage stabilizing characteristic consistent with technical specifications? 1.6 is the voltage stabilizer and ripple coefficient consistent with the technical specifications under the rated load? 1.7 when replacing a large fan, does your power capacity meet the requirements? 1.8 general au
