Speed up your BSNL BroadBand [Guide]

By Bandhan Preet Singh On Dec 24, 2012

If you are using BSNL Broadband service and not happy with it as you do not get the speed which you have opted for, then you need to know that the Broadband Speed does not depend solely on the Broadband Plan you have opted for. There are multiple factors that affects your Broadband Speed. Here is a list of suggestions which you can use for a better experience on your BSNL Broadband connection.

1. For Reliability & Speed, Use following DNS Addresses:

A) On Dial-up or Bridge mode Broadband connections.

Enter following DNS address at Local Area Connection or Wireless Network Connection.

Primary DNS – 192.168.1.1 (Filling this IP will automatically takes first DNS server from BSNL)

Alternate DNS – 156.154.70.1 or 156.154.71.1 or 4.2.2.2 or 208.67.222.222 or 208.67.220.220 or 8.8.4.4 or 8.8.8.8 (Use any of these)

B) Automatic or Multi-user or PPPoE mode Broadband connection.
Login inside the Modem or Router Interface and enter the following DNS address
Primary DNS – 156.154.70.1 or 156.154.71.1 or 4.2.2.2 or 208.67.222.222 or 208.67.220.220 or 8.8.4.4 or 8.8.8.8 (Use any of these)
Alternate DNS – 156.154.70.1 or 156.154.71.1 or 4.2.2.2 or 208.67.222.222 or 208.67.220.220 or 8.8.4.4 or 8.8.8.8 (Use any of these but it should be different from Primary DNS)

2. Check SNR Value:

SNR (Signal to Noise Ratio) Margin value at Downstream must be greater than 13 dB. See DSL Line Parameters in Modem Interface Page under the heading Overview or Device Info or Status or Statistics. If value is lower than 13 dB then insist the BSNL line-man for change of line, Jumper, Vertical, DP or Pair. Broadband may work higher than 7 dB SNR Margin but you will experience slow speed, frequent disconnections and time out.

3. Check Attenuation Value:

Attenuation value at Downstream must be less than 43 dB. See DSL Line Parameters in Modem Interface Page under the heading Overview or Device Info or Status or Statistics. If value is greater than 43 dB then insist for Change Phone Line (Drop Wire), Jumper, Vertical, DP or Pair. Broadband may work higher than 43 dB Attenuation but

you will experience

affected speed, frequent disconnections and time out. Practically it’s not possible to provide a line with exact values of SNR & Attenuation. So variations could be there.

4. Choose Right MTU Size (Maximum Transmission Unit):

Almost all MTU sizes (like 1500, 1492 or 1480) give good speed performance among all website browsing & downloading. It is defined inside the Modem or Router configuration page. But one should preferably use 1492 as MTU in all Modem/Router connections until & unless one faces any significant problem with MTU.

5. Always use ADSL Splitter:

ADSL Splitter must be used on a Telephone line at the subscriber premises. It actually divides main (frequency) Telephone Line coming from Exchange into Phone (Low frequency) and Broadband (High frequency) connection.

6. Right Physical Layout:

Physical Layout of line must be in accordance with the technical norms followed for Broadband connection i.e. Phone Line coming from DP/Pillar Side must be first terminated at an ADSL Splitter in a subscriber’s home.

7. Use Multiple Telecommunication devices only after Splitter:

There should be –

a) No Parallel Phones Connection,

b) No Intercom,

c) No EPBAX,

d) No Joints/Cuts in Line,

e) No Conduit/Internal Wiring.

8. Use Good Quality Wires:

For a Telephone having a Broadband connection, avoid PVC wires & other non-Telecommunication wires. Instead Use Drop Wire (Copper) supplied by BSNL.

9. Keep the line path away from any Interference:

Telephone Line Path should be away from Electrical Lines & Electrical or Electronic Appliances/Equipments/Devices.

10. Keep Connecting Terminals Clean:

All the Connecting Terminals or Points must be Clean & should be free from Rust,Dust and Carbon.

11. Cover Joints:

Proper Insulation & Tapping of Joints must be done at all points or terminations. Don’t let any joints open or hanging loose in the air.

12. Check Loose Connections:

Telephone cables, Drop wires, LAN & USB cables should be tightly & properly connected for proper flow of data transmission.

13. Choose Right Media:

For faster speed, LAN (Ethernet) Cable should be preferred over Wireless medium & Wireless (Wi-Fi) should be preferred over USB Cable for Broadband connections.

14. Avoid Joints/Cuts:

Check Telephone Line/Drop wire for any Cuts & Cracks and replace the same. If possible Use single wire without any Joints.

15. Noise free Line:

There must be No Noise & Disturbance in the telephone line. Pick the phone receiver and dial any digit and hear the sound, if any. Any good line has no noise disturbance.

16. Use Proper & High Quality Splitter:

If SNR or Attenuation levels are not at recommended levels even after Line Change etc. then try to change Splitter to see any difference in the values. Sometimes internal circuit of splitter becomes faulty & gives false parameters.

17. Use Proper & High Quality Modem device:

Modems of different Companies or different Models of Modem have different Internal Circuitry and they read line parameters differently. So if Line parameters are not at recommended levels then change Modem to see the difference.

The Modems like Teracom, Huawei, UT-Star, TP-link, D-link, Netgear and Link Sys perform exceptionally well even in poor signal to ratio conditions also. That means if your house is at considerable distance from nearest BSNL exchange, naturally the line attenuation will be more and the cheap quality Modems would fail to perform reliably or read line profile.

18. Use UPS for Stable Power Supply:

Try to Use power supply from a UPS (Uninterrupted Power Supply) for Modem & Router’s adapter to avoid any kind of power fluctuations.

19. Use Correct Modem Adapter:

Use Modem Adapter as per the Original Current & Voltage ratings given & printed on Modem box. Using low voltage or current rating adapter may cause Modem & DSL to become unstable.

20. Prefer PPPoE settings over Bridge Mode of Connection:

PPPoE (Always ON) settings are much stable, secure and faster than Bridge (Dial-up) settings. Even if there is High Attenuation and Low SNR the Broadband connects & works well for most of the times. Infact, Hackers can’t access your PC easily in PPPoE mode connection as the Modem is dialing to the server & comes in between PC & Internet for security point of view.

21. Check Line Profile:

The default Line Profile of a broadband connection (DSLAM port) is generally 2 Mbps (2048kbps). But sometimes speed problem comes in case of a 4 Mbps or higher plan & the speed does not cross beyond 2 Mbps. Then one needs to check whether the Line profile configured correctly as per the selected Broadband plan, as the wrong profile freezes the speed at certain level.

22. Select Right Modem Settings:

Always Enable NAT, Firewall and Default Route check-boxes (features) in the Modem configuration/interface page.

23. Disable Automatic Updates of Softwares:

If possible, disable Automatic Updates of most of the third party programs installed in your computer. Instead choose or change their settings to Manual updates available in the options/feature button. These programs sometimes, run in background and consumes data without the knowledge of the user.

24. Remove unused Software Applications:

Uninstall Unnecessary Softwares like Web Toolbar, Add-ons, browser extensions, Screensavers, Weather updates, Desktop Gadgets etc, as these consumes data, at times.

25. Install Good Anti-Virus:

Use a good Anti-Virus with Internet Security suite for extra protection from Malwares. As most of the speed is hogged by Viruses, Trojans, Worms, Spywares, Adwares etc. likely present in all computers due to use of pen drives & online activities.

26. Choose a better browser:

One should use Mozilla Firefox, Google Chrome and Opera for Web Browsing which is faster, safer and reliable than the conventional Internet Explorer which is embedded in windows.

27. Install updates on Time:

Install all Security and Essential updates regularly from Microsoft if you are using Genuine Windows. Those who are using other operating system should also follow the same.

28. Only one ADSL splitter per Line:

Never use Two ADSL Splitters on same line for any parallel phone connections. Instead use phone extensions for using multiple telephone connections.

29. Secure your Wi-Fi connection:

Never let your Wireless Modem or Router unsecured. Use WEP-128 bits or WPA security key settings. You may also use MAC based security. Choose strong Wi-Fi password containing both letters & digits.

30. Keep a Tab on Torrent or Hidden Softwares:

Most of the torrent softwares keep running all the time in the background which may reduce your browsing speed. So better quit the application if its not in use.
