How to Rectify Slow Internet Speed

Problem --- Specially for Broadband

Engineers.For Reliability and Speed use following DNS addresses at every broadband connection.

Primary DNS -- 192.168.1.1 (giving this IP will automatically takes first BSNL DNS

available through DSLAM)

Alternate server -- 208.67.222.222 or 208.67.220.220 or 8.8.4.4 or 8.8.8.8 (use anyone of

these)

Dear friends, the Broadband Speed does not alone depend upon the DNS or IP Settings.

There are multiple factors that boost speed on the Computer. Just for your knowledgeand for better understanding you can note down following points and keep it in mind.

For Reliable and Speedy Internet Connection :-

1. SNR value must be greater than 13. See DSL line parameters in Modem. If value is

below than 13 then change line, vertical, DP or pair.

2. Attenuation level must be less than 40. See DSL line parameters in Modem. If value is

greater than 40 then change line, vertical, DP or pair.

3. ADSL Splitter must be used on a Telephone line at subscriber premises.

4. Physical Layout of line must be in accordance with norms followed i.e, Phone Line

coming from DP/Pillar Side must be first terminated at a Splitter in subscriber's home.

5. Also Before splitter there must be ----

No Parallel Phones Connection,

No Intercom,

No EPBAX,

No Joints/Cuts in Line,

No Conduit/Internal Wiring.All the devices must be used after ADSL splitter.

6. For telephone and broadband connection, Avoid PVC wire and use Drop Wire (Copper)

Instead.

7. Telephone Line Path should be away from Electrical Lines/Equipments/Devices.

8. All Terminals or Connecting Points must be Clean and Rust free.

9. Proper Insulation and Tapping of Joints must be done. Don't let any joints open or loose

in air.

10. Telephone wires, LAN Cables, USB cables should be tightly connected for proper flow

of transmission.

11. For fast speed, LAN Cable should be preferred over Wireless Broadband and Wireless

should be preferred over USB Cable for Broadband connections.

12. Check Telephone Line/Drop wire for any Cuts & Cracks and replace the same. Use

single wire without any joints.

13. There must be No Noise and Disturbance in the telephone line. Pick the phone receiver

and dial 5 number digit and hear the noise if any, any good line has a complete silence.

14. If the distance (underground cable) of the subscriber's modem is more than 2 Kms fromthe Telephone Exchange (DSLAM) then Use only G.dmt Modulation in the modem DSL

settings. Disable all other modulations.

15. Try to Use power from UPS supply for Modem's adapter to avoid fluctuations.

16. Use Modem Adapter as per the Original Current & Voltage rating given/printed on

Modem. Using low voltage or current rating adapter causes DSL to become unstable.

17. PPPoE (Always ON) settings are much stable and faster than Bridge (Dial-up)

settings. Even if there is High Attenuation and Low SNR the Broadband connects and workswell most of the times.

18. If the Line quality is not so good or the Broadband plan or speed requirements are less

than 2 Mbps (like in the case of unlimited 256 Kbps Plan) than tell your NIB Staff to Lower

the Profile of Broadband connection to 1 Mbps from 2Mbps. It will make your SNR to go

up and Link stability increases.

19. You can Delete/Disable all the irrelevant PVC values in the WAN settings of the

modem other than 0/35, 0/100, 0/32.

20. Use DNS or IP settings as told on the top of the article.

21. Always Enable NAT, Firewall and Default Route in the Modem configuration page.

22. Disable Automatic Updates of most of the Programs in your Computer.

23. Delete/Uninstall Unnecessary Softwares like Web Toolbars, Screensavers, Weather

updates, Desktop Gadgets etc. from the computer.

24. Use Professional Anti-Virus with Internet Security suite for added protection fromMalwares. As most of the speed is hogged by Viruses, Trojans, Worms, Spywares, Adwares

etc. present in computer.

25. Use Mozilla Firefox, Google Chrome or Opera for Web Browsing which are faster,

safer and reliable than Internet Explorer.

26. Install all Security and Essential updates from Microsoft if you are using Windows in

your computer.

27. Use Download Manager for Downloading Files rather than using inbuilt windowstraditional downloading and saving files. As the Download Manager uses specific technology

which boost speed many times (i.e, Utilises full bandwidth available in your Broadband

Plan).

28. Prefer Windows XP or Windows 7 than Windows Vista for using Internet as the latter

is slower in response to others OS while using Internet.

29. Never use Two ADSL Splitters on same line for any parallel phone connections, Insteaduse phone extension for using multiple connections.

30. Never let your Wireless Modem/Router Unsecured. Use WEP-128 bits or WPA

security settings.

31. At MDF Side (in telephone Exchange) all connections, jumpers and fuses should beneatly connected.

32. In E10B exchanges we can avoid using GD Tubes in Fuses. It can increases Line

Quality (SNR value).

33. Last But not the Least, Pillars and DP should be free from Dust and Rust.

There are several other factors at various levels which affects Internet speed but most of the

above points are enough to be checked at subscriber's premises .
