ADSL Splitter Internet Problems and their Solutions
If you are having an ADSL / DSL broadband connection at home or office then you must have heard of and seen a device called ADSL / DSL splitter installed between your modem and telephone line. It looks like a small rectangular box with three RJ-11 connection ports, one for input line and two for output for Phone and ADSL Modem. Many people don’t know about the proper use of ADSL Splitter and how to resolve some of the problems that can arise due it. So here is a detailed guide on ADSL or DSL Splitter and its advantages and disadvantages.
What is an ADSL Splitter?
ADSL Splitter is a small device that is used to separate voice signals (analog signals) from data or broadband signals. If you have a DSL/ADSL broadband internet that comes from your telephone line then there is a need for you to have an ADSL/DSL Splitter. This is only in situation where you want to use your phone and broadband modem simultaneously. If you do not have an ADSL Splitter installed then there will be interference in the telephone line and you will hear hissing or noise when you pick up or use your telephone if the modem is powered ON. Also your broadband internet will also get disconnected when you use your telephone in the middle of your work.

Advantage of Using ADSL Splitter
Here is the only advantage that you can get by using a ADSL Splitter for your ADSL Internet connection.
Use Both Devices Simultaneously
By using an ADSL Splitter you can use your telephone and broadband modem simultaneously and that too without any noise in the phone receiver and also no disconnection from internet.
Disadvantages of using ADSL Splitter
Here are some disadvantages or problems that can occur by using an ADSL Splitter.
Frequent Disconnection
If your ADSL Splitter has become old or faulty then you will experience frequent disconnection of your broadband internet that can become very frustrating for any user. ADSL Splitters are passive devices equipped with capacitors, and with passage of time the capacitors loose their charge, effectiveness and performance, so it is advisable to change your ADSL Splitter every six months or so.

Reduced Internet Speed
A cheap and old ADSL Splitter can have negative impact on your broadband internet connection and can result in the reduced speed of your internet connection. In this case you have to either get a good ADSL Splitter or remove the ADSL Splitter and directly plug in your telephone line in the modem. ADSL Splitter from D-Link and TP-Link are of very good quality and offers very good performance. There are various ADSL models available in the market but the good ones are SP-208, SP-206, SP-204, SP-202 and SP-201.

Conclusion
ADSL Splitter is not necessary for everyone because if you have taken a telephone line especially for the purpose of Internet and have not installed any phone to this line then you not require an ADSL Splitter, but in homes where people generally have only one phone line for both telephone and modem then it becomes necessary to use an ADSL Splitter for proper functioning of both the devices.

Nice article on splitter.
But is there a way to determine if splitter is ok or not
I have changed from default sp202 a linl splitter to dlink cf 30, which i have handy when i experiece frequent internet cuts.
hope that you will give a solution
If your ADSL keeps disconnecting or you hear fuzzing noise on your phone then the splitter is not ok.
Thanks.
Nice valuable reply.
I came across so many websites advising against usibg spliter to modem connection . My connection is tele main wire -rosette box one way- line-splitter-modem
Same spllitter -tele
Is this ok?
Does the splitter default sp202a change to cf30 dlink will affect modem
I did not get you.
I thinkk that you need more particulars than i supplied.
The default splitter that came with the pack of dlink 2730 u model was sp202 in which i had the problem after 21/2 years. I was having a dlink cf30 in hand for replacement and replaced and working now. Is that any capability change that would affect the internet connection or modem itslef that is the query i want you to ansser.
Regarding connection, it was mostly in net surfing sites, that it was mentioned that there should not be any splitter to the modem, but only to the phone to streamline the noise level.
Your article in the conclusion part tells that splitter is only needed if you have one line for both telephone and modem for internet purpose
I have given the connection part in this regard if it is correct or not
main line ->oneway rosettebox->Line->splitter->modem
same splitter ->phone
Now i think i made it clear for you
What is the difference in splitter model. please
Splitter is only needed when you want both modem and phone to work simultaneously without affecting each other. The connection to the splitter that you have specified is correct. The difference between the splitters is the circuit. Good splitters have better circuit and use more components while a cheap only has one or two components including a capacitor.
Thanks . I also read the recommended splitters and found cf3o one among them.is the cf30 model by dlink?
There are articles of related topics.
I suggest you prepare a list of all the articles subject wise that would catch the attention of users quickly
Can frequent disconnection be caused by insufficient ports ? When there are too many internet users trying to connect their modems to the internet service provider’s exchange hub ( ports ), the connection is difficult to establish or if when the connection is established , the connection is frequently dropped.
It can be a possibility especially when the SNR from the server side is low.
Nice article on splitter
Kindly indicate the brands of good quality splitters.
Hi.is adsl splitter sp316 better than sp 201.or vice versa. I use bsnl broadband.
Both are good but i think SP-316 is a little better.
Where can I shop for good splitter?
Try on amazon.
I have changed splitter but then also the noise on telephone comes.
But when I connect directly to telephone without splitter and router.then the telephone sound comes at zero level.help please!
I have been using A splitter since more than 2 years. Although it was working perfectly, since 5 days a bizarre situation has come forth.
1. When direct wire is inserted in telephone, it works perfectly
2. But when the phone is connected using a splitter, there is no dial tone in phone.
3. I have tried changing the multiple splitters but the situation mentioned in point 2 persists.
Please advise.
