Troubleshoot Slow Internet Connection – Comprehensive Guide for BSNL Broadband Users

BSNL Broadband PlanA slow connection is every Broadband User’s nightmare. Everyone wishes to enjoy Internet connection at the ISP promised speed. However, due to several depending factors this does not happen, and ISPs promise speeds up to XX Mbps for this reason. Here are certain important things you need to check if you experience slow internet speeds. Today, in a friendly gesture towards TelecomTALK readers, Mr. Bandhan Preet Singh, Computer Engineer at BSNL has shared a troubleshooting guide which will help you find the cause of slowness of your Internet connection. We appreciate Bandhan’s efforts in coming up with this comprehensive guide and thank him for sharing it with us. Also, folks who read BSNL stories here would instantly recognize Bandhan as the BSNL employee who responds to comments.

SNR, Attenuation Value

SNR (Signal to Noise Ratio) value at Downstream must be greater than 13 dB. Attenuation value at Downstream must be less than 45 dB. See DSL Line Parameters in Modem Interface Page under heading Overview or Device Info or Status or Statistics.

MTU (Maximum Transmission Unit)

Almost all MTU sizes (like 1500, 1492 or 1480) give good speed performance among all website browsing and downloading. 1492 is recommended.

ADSL Splitter

ADSL Splitter must be used on a Telephone Line at the subscriber premises if the user is having a Broadband connection. Modem must be fed with pure ADSL signal. Use Multiple Telecommunication devices only after Splitter

Interferences

Telephone Line Path should be away from any kind of lines and devices which create an electromagnetic field. All the Connecting Terminals or Points must be Clean and free from Rust/Dust/Carbon. A noise free line is recommended

Devices

A good quality modem with wiring is highly recommended.

Bridged or PPPoE

PPPoE (Always ON) settings are less stable than Bridge (Dial-up) settings. In cases where you are unable to connect well most of the times, switch to Bridged.

DNS Addresses would play a great role when it comes to opening all websites. You must consider using Google DNS or Open DNS forbetter experience.

  • Google DNS: Configure your network settings to use the IP addresses 8.8.8.8 and 8.8.4.4 as your DNS servers
  • OpenDNS: 208.67.222.222, 208.67.220.220

Right Plan for Right Purpose

One should use right broadband plan for the right kind of activity. If you use only email and social networking sites, cheaper plans with smaller FUPs would be sufficient. For video streaming and lot of content downloads you must opt for larger FUPs which will cost more.

Last but not the Least, Wires and connections installed in Pillars and DP boxes should be free from Dust and Rust for good line parameters.

    Hello Sir,

    I am trying to configure the Smart DNS IPs in my windows XP by refering to the below steps.

    1. Click Start, click Control Panel, click Network and Internet Connections, and then click Network Connections.
    2. Right-click the network connection that you want to configure, and then click Properties.
    3. On the General tab (for a local area connection), or the Networking tab (for all other connections), click Internet Protocol (TCP/IP), and then click Properties.
    4. Click Use the following DNS server addresses, and then type the preferred DNS server and alternate DNS server IP addresses in the Preferred DNS server and Alternate DNS server boxes.

    After configuring the DNS IP’s on your device please restart your device for the configuration to take into effect.

    But when I restarting tata docomo 3G brodbond above setting disappears. Support told me to check router setting of my network.

    Please guide me how to set it for Tata docomo 3G device

    Thank you!

    I’m using the bsnl broadband connection. I wanted to shift my house to another house which is 2 km from my present home. Wen enquired with the bsnl staff they were saying the new house and the post (pole) in which the box is kept is more than 500 metres (wire has to b put that long)and only phone line will work properly it seems and that I will b frequently facing problems with the Internet. The distance between the present home and the pole is 25 metres only. Is it true??? Or should I go ahead with the transfer of my phone to the new house thinking net will work properly. ???

  • ad May 6, 2014 11:14 am

    i do not have those problems

    The Biggest problems is still on 512kbps has not upgraded their speed!! since 2011 reality max speed you get 61KB

    now i have try evdo leave this slow Junk

  • Simon D April 12, 2014 1:21 pm

    If DSL SNR is low , first connect the external line directly to the Modem
    ie, without splitter and telephone.
    NOW check SNR if OK, check internal wiring otherwise book complaints to 198

    • Aneesh - Chennai September 13, 2014 6:18 pm

      Connecting line directly to modem without splitter worked for me. Thanks

  • Prithvi April 4, 2014 7:37 pm

    Is this applicable for BSNL Pune? If not how can we come across someone like Mr. Bandhan who can guide BSNL BB ADSL users from Pune Branch?

    • Bandhan Preet Singh April 21, 2014 1:30 pm

      Hi,
      Pls tell Pune BSNL to read this article and act wisely. You may call the local BSNL broadband engineer to go through the content and give it wide publicity.
      Do not forget to share this article. ;-)

      • Prithvi April 21, 2014 1:43 pm

        I’ll try to get Pune Div to send their feedback.

    I m in search of 3G unlimited with less rental/recharge

  • hebin Mohammed March 27, 2014 7:41 pm

    This is good. One more point, if telephone impedance becomes low for some reason, net wont work properly, and attenuation shown in modem increase and snr value decrease. To know whether phone impedance is low, check snr and attenuation values after disconnecting the phone from line and before. If improvement of snr and attenuation value is observed after disconnecting phone from the line, try replacing the telephone or avoid connecting phone to telephone line while using internet.
    One more thing, if you dont use land line quite often, and DSL lamp is blinking, try giving a few full rings to your land phone for three or four times. this worked for me many a times, to stabilize the DSL or LINk or LINE Indicator.

    • Bandhan Preet Singh March 29, 2014 1:04 pm

      Nice observation dear..!!

    • ARUL RUBAN S March 29, 2014 10:00 pm

      No need to disconnect / replace telephone, just check spiliter .if any green color then replace it with a new one. don’t use parallel line to modem& phone. Plz ask BSNL technician for solve the issue.

  • ARUL RUBAN S March 26, 2014 10:08 pm

    3 points for solve slow problem

    1. Better Telephone Line ie. SNR should be greater than 6dB
    My Home is 6km away from exchange . my modem values,

    SNR (Downstream) – 6.15 dB
    SNR (Upstream) – 19.5 dB
    Max Att Downstream Rate – 2160 kbps
    Max Att Upstream Rate – 996 kbps
    Line Attentuation(Downstream) – 65.0 dB
    Line Attentuation(Upstream) – 36.0 dB
    Connected Standard – ADSL2+

    2. Use proper MTU size
    1480 or 1500 recommended.some modems doesn’t support 1500 so better to use 1480. if u face problem like not opening yahoo site, use 1452.

    3. Use DNS Recommended by BSNL (Try to save DNS values in modem not in pc)
    for p3 network 218.248.255.139, 218.248.255.146 , 218.248.255.147
    for p2 network 218.248.240.179, 218.248.240.180, 218.248.240.181
    if u need, try google open DNS 8.8.8.8, 8.8.4.4

    • Bandhan Preet Singh March 27, 2014 12:52 pm

      @ Arul, as per your Distance the line parameters are fine. I request you to use G.dmt modulation in modem. As the distance is large nothing can be done in this connection. Attenuation is high and SNR is quite low. I request you to use Line profile 1mbps if your Broadband plan speed is not greater than 1mbps.
      You will see your SNR above 10db for sure. it will give stability.

    Thanks…some very basic steps for a great performance. Indeed a great effort Mr.Bandhan. I just wish all the tech employees of BSNL had the same attitude towards the customers as you…

    • Bandhan Preet Singh March 25, 2014 12:56 pm

      Thanks Biswadeep ji,
      i feel that there are many limitations and issues to be settled at our end but still all BSNL employees are trying hard to compete with the present demands/aspirations of the users.
      We need govt support to give best & cheapest services to the Nation.
      We all must remain alert and highlight genuine issues to the highest authority. Only an aware citizen and a smart user can make best out of it. We also need to shed the govt setup and be ready to serve you all with the same spirit as in Private company.

    BSNL is providing Really Cheap 3G Plans

  • Althaf March 24, 2014 8:47 pm

    I am using bsnl broadband from the last 3 year from Kerala( Actually I dont have any other option ) . 750 ul plan . I never get my SNR value more than 10 db . I registered many many many many many complaints , I cant remember how much time I complained . . Now I STOPPED complaining . Because I never got solved . The technician at my local exchange has no idea about SNR values . Every time he completes his job whether there is no noise at line .
    Look at my values

    • Bandhan Preet Singh March 25, 2014 12:13 am

      If the cable distance b/w your House and BSNL office (DSLAM) is more than 3.5 kms then officially BSNL can not do anything as it is technological (ADSL) limitation. You must use G.dmt modulation and set your Line profile as per your plan. As you have poor line parameters then you may request NIB office to give you 1mbps line profile (as ur present 750 BB plan will have maximum 1mbps speed) so that SNR jumps b/w 16-20db. You will get stability.
      One thing more, you must check your speed at any Speed Test site and if its ok then no need to do anything extra. Do not look at SNR then. just relax. Sometimes we can’t go beyond technical limitation.

    Can anyone plz say… In bsnl night unlimited(stv 389).. Does it get disconnected automatically at 6am or does the currency cuts if it does not disconnect…??

    • Darshan March 24, 2014 8:14 pm

      Yup balance get deducted after 6am

    • BIBHAS March 24, 2014 9:03 pm

      No, Your available balance will be deduct.

    • Raghava March 25, 2014 10:50 am

      Data STV389 is unlimited data between Night 00.00 Hrs to Morning 06.00 Hrs. After this hours the data will be charged at 2 paisa/10KB.

      Hence it is recommended to use unlimited data STV389 along with other Data STV like 139-1GB or 251-2GB, to avoid excess of Data charging after unlimited hours.

  • Sudhakar March 24, 2014 3:51 pm

    To telecomtalk :

    You always miss one of the most important information in every news. In this news report, you have missed the information below :

    Check the maximum link speed (not the download speed) and the maximum speed supported by the modem in the modem’s console. All models as for now will support only upto 24 Mbps download and 1 Mbps upload speed. The link speed is configured at your ISP end which is the maximum supported speed between the modem and the port for your connection ISP’s main node.

    In BSNL, some cases, when we give plan change from low speed to high speed, the link speed does not change. They will say that it gets changed automatically. But it does not change in some cases. They will try to put the blame on our side. You will have to point out this link speed and make them understand.
    If they do not agree to change the link speed, tell them that you will complain to the DoT to take severe action. Then thy will change.

    • Bandhan Preet Singh March 25, 2014 1:00 pm

      thanks for the tip…. the point is already highlighted in my article. Pls see point heading “Check Line Profile”.
      Every user must check their line profile given in the modem and it must be in accordance with the plan you have chosen. Lower or higher line profile as compare to Broadband Plan has their own disadvantages. Pls read the FULL article at the link provided at the end of the above TT article.

    I wonder how can I :

    “Ensure Proper Connections in Exchanges too

    All connections, jumpers and fuses should be neatly & tightly connected at MDF Side of the Telephone Exchange.”

    • Bandhan Preet Singh March 25, 2014 12:17 am

      rightly pointed out…. its written as BSNL employees will also read this article and help our esteemed customers. Even in some cases… people do visit exchange offices.
      this guide is useful for both Staff & Customers.

  • sujay March 24, 2014 2:41 pm

    Info is nice. But the main problem with govt property… Also the employees at exchange are really noobs to understand the broadband guidelines. Even they didnt know the difference between kb and mb. Then how subscribers can be satisfied with such kind of service. Plans are good for bsnl. Comparing with local cablewala Internet is fer better then bsnl… Speedtest results is quite aweome with 1ms ping. One more suggestions use tcp optimizer its also a good optimizing software…

    • Bandhan Preet Singh March 25, 2014 1:02 pm

      TCP optimizer works well only in Windows XP. and i have already mentioned about MTU size in my article. You may also google and see more info about it. pls share here for the readers welfare.

  • Akhil Mohan March 24, 2014 2:34 pm

    simple tip
    for those who dont want unlimited connection, ditch bsnl and use avoid 3g

    • Sugu March 24, 2014 4:31 pm

      @Akhil Mohan: Nope. BSNL gives me 8GB @Rs.700 at 2Mbps! And I’m happy to say the speed is always above 200kB/s. In my area, only BSNL and Idea has 3G (Kottayam, Kerala) and after 9pm, both won’t go above 20kB/s even though on 3G plan. And Idea still charges High rates as well! Idea even has H+ but still at night, speed is pathetic while my broadband connection is constant, @1.8Mbps…

      • Akhil Mohan March 24, 2014 7:34 pm

        If you are getting good speeds, you are very lucky. Continue using BSNL because it is offering broadband at really cheap prices. I was only suggesting that if you are someone who uses internet in a limit , then you may also use 3G (only if you are not getting good service from BSNL).
        I am also from Kerala, Ernakulam. Here I use Idea 3G and spend around 600 Rs per month on internet. I find Idea 3G the best option for internet as the speeds are always above 2 Mbps, even on peak hours.

        I was a BSNL BB customer earlier (PLAN 750), got fed up with their pathetic service. For whole 2 months there was no internet, but I had to pay the bill. Their employees behaviour is unbeleivable. You won’t believe, but they said ” Venamengi upayogicha mathi, Ningal connection cut cheythal enikku oru pullum illa”

        • Sugu March 24, 2014 10:00 pm

          @Akhil: Ernakulam. Thats highly developed city, compared to it, Kottayam is just “Pattikad”. Have you tried Docomo 3G. Its not available here, but I get awesome 3G offers, 2GB @ Rs222 1GB + 222TT @ Rs.250
          Yea, I can believe that, Even 2 years ago, this was the response… If I tell technical details, “Than kuduthal onnum ondakanda, jhangalku enthacheyanda ennu ariyam” But for the past one year, they became real decent…! They patiently listen and solve the problems..

          • Akhil Mohan March 25, 2014 12:41 pm

            ur experience is worse than mine. And i have full 3g coverage from the 3 operators. I have earlier used docomo. Then they had that 40 minute problem. Now i am fully satisfied with idea. 4gb 3g for 448 rs. Bsnl 3g even with full coverage has frequent downtimes. It works fine for 30 minutes, then it remains dead for 10 mins

            • bharat thumber April 12, 2014 9:39 pm

              great job bandhanji…
              my observations say that speed for getting upto 2 mbps snr should be more than 7db and attenuatin should be below 50………. and if customer have two parallel lines than using splitter at both end will solve d problem of adsl blinking (line drop).

              • Bandhan Preet Singh April 24, 2014 8:15 pm
