Thread: Poor SNR

Dear all,

I am experiencing poor SNR abt average figure of 8. Could you please suggest methods to improve the ways so that my internet speed and connectivity is going to be good.

Thanks in advance,

Take care,
Rajan

Get your line checked.

also make sure ur line is straight as much as it can.

i too had poor SNR........got it solved by making the line straight.

1.
Mention your modem model and make.
2.
Change Mod mode to GDMT

3.
Connect all phones AFTER ADSL splitter.
( No parallel connections from Main Phone Port ).

4. In computer
Start RUN type cmd Ok
new window
type ipconfig /all
checking DNS. Use 8.8.8.8 and 208.67.222.222
( google and open dns )
5.
Report full data Mod selected
SNR ATTN line speed Rate. (U/L D/L). other data not needed.

UPDATE: Please avoid posting same problem in different threads.
Noted Your modem is UT300R2.
When BSNL staff tested, then and there, they should have checked the line conditions. ( they have special equipment )
If the modem is on RENT or purchased within a year, get an exchange from BSNL.

Check the Wires

The leading-in cable (drop wire) from the junction box (DP box) to your house should be as straight as possible, should be of a single length without any joints. The wires should not be coiled anywhere and should be away from electrical lines. With these types of irregularities, i.e with joints or coiled or near power cables, your phone might work fine but the DSL link may not hold and work satisfactorily.

Splitters and Parallel telephones

Never by-pass the splitter. The splitter does the job of separating the high frequency ADSL signals from low frequency telephone signals. If the splitter is not installed correctly, the broadband connection is likely to go down every time the phone rings. Any parallel phone connections should be after the splitter and not before it. The line from the exchange should first enter into the splitter’s Line jack. The phone should be connected only to the phone jack of the splitter. The ADSL modem should be connected to the modem/DSD jack of the splitter. A two way jack may be connected to this phone jack to install your parallel telephones. The wire leading into the modem should not be running parallel or close to electrical wiring.

Signal to Noise Ratio (SNR)

The SNR should be higher than 20 though anything above 10 is just enough. The Attenuation should be as low as possible. But if the attenuation starts going higher than 40 and SNR going down below 10, it is time to complain about the line condition to BSNL.
