SNR ratio is your line strength. The more the better. Too many joints, old telephone wire and noisy neighborhoods can bring down your SNR rates.
0-10 - very bad
10-20 - little bad
20-30 - good
30-40 - excellent
40-50 - congratulations, you live right next to the exchange

Attenuation is the distance from your home to the exchange. The lower the better and it means your closer to your exchange.

Different plans show different SNR rates. So if your getting 30db on 256kbps-2048kbps connection, You may get 40db on a 256kbps unlimited connection. So be sure to mention your plan.


Here's mine:

SNR (Downstream) 34.5db
SNR (Upstream) 22.5db
Line Attentuation(Downstream) 12.0db
Line Attentuation(Upstream) 5.5db

Data Rate 2040 Kbps 510 Kbps


Connection Plan: BSNL BB Home Combo UL 625

Broadband speed : 256Kbps

Download/Upload Limit : Unlimited

Price : 625

How do I check this? Nothing opens when I hit 192.168.1.1, my router status opens when I hit 192.168.0.1, and this is the whole page,

Needed to update this old 3 yr thread. Please post your present data. My Connection is TOO much unstable nowadays.. The DSL and Internet light blinks and disconnect at least 15 times in 1 hr, there's not a single time where i could utilize my net full potential. Even when editing this, my dsl was unstable 3 times.
