How to Trouble Shoot Continuously Disconnecting Broadband DSL Link?



How to trouble shoot continuously disconnecting broadband DSL link?
Internet is a marvelous innovation in the sense that it made the whole world into a small village. People living in far away countries and immediate neighborhood are same for a netizen. Broadband made this transition a pleasant experience with its agility. People who enjoyed this experience will be much aggrieved if they are made to sit in front of a computer with an interrupted DSL connection. As the broadband net connection is relied much on telephone cables (Channel cables too) this kind of interruption is likely once in a while. The reasons are many including rusty cable connections, faulty splitter, fault of modem and the malfunctioning telephone receiver itself.
In this article we will be discussing about how we can isolate the faulty component so as to resolve the interruption.
Telephone cable
As I have already said, the role of telephone cable is much greater in the realm of internet than all other components that the likelihood of its failure is higher. Just lift your telephone receiver and listen to the dial tone. If the tone is not clear and you can hear some other noises too along with the tone your telephone line is faulty. DSL connection will be hardly lingering for more than five minutes. As the telephone cables are laid mostly underground and much of the lines are lying far away from our home there is very little we could do about a faulty cable rather than call the telephone personnel and make a complaint.
Splitter is the second component comes in line after the telephone cable. A splitter divides the signal into two parts one part containing the ADSL signal and the other containing only voice.So that you can make telephone calls along with internet without being disturbed by the cooing sound of internet. If your telephone line is OK and you suspect your splitter is at fault just remove the line connection from the splitter and connect it direct to the modem and start browsing. If the DSL stays there without any problem you have to suspect your splitter. Just remember that the DSL will go out if someone tries to call you on phone during this time. If you are a person who receives a lot of calls on landline during day time you have to conduct this experiment in the middle of the night. As the splitter is not a costly component.(it costs only Rs.30 - Rs.50 only ) you can replace it without much worries. But before you replace it please check its contacts. If you can see rust lying on the contacts, remove the rust using a flat screw driver or other sharp objects. You may check the telephone line contacts also for rusty substances. Once all of them are cleaned well you can try the connection to check the DSL status.
In some cases the telephone receiver itself turns out to be the villain. In order to check it you can remove the outbound telephone line from the splitter leaving inbound telephone line and line to modem intact. Your phone receiver will have no dial tone now. Start internet browsing and check for any interruption. If the interruption has gone it is sure that the interruption is coming from the telephone receiver. In order to solve this issue you can purchase one more splitter and serially connect in between the first splitter and the telephone receiver.
If all the above components have been tested and the problem still remains you may borrow your friends modem and check the DSL status (you needn't change the username etc to check the DSL status). If the new modem works well, you can take your modem to your friend's house in order to give it a last chance to prove its worth. If it behaves same at your friend's house too, your modem is faulty and you have to replace it.
The cases of modems become at fault are very rare and nine out of ten cases it is our cheaper components at fault - the telephone cable, splitter or the phone receiver.
