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
.
