What exactly you played with your router to increase SNR ?

Yeah... I don't mind giving reps... if a person has done some work to help others on this forum... I'm always 1st to rep him...
Any1 feels nice to get recognition for his work.... so, in a way its a small appreciation from my side...

thanx for ur rep...

I changed router's mode from ADSL2+ to G.DMT... it worked wonders... downstream rocketed from 9 to 41... u can give it a try too... but if it doesn't work... revert back to ADSL 2+...

To whom should I write the written complaint & to whom should I submit...

To the divisional engineer at the exchange.

how do I measure / check my SNR & line attenuation ?
is some software / hardware required for the same ?

my ADSL comes through Copper cable , joints galore along the way from around a distance for abt 4 -5 km frm the Exchange , after the Dp Pole it goes directly to the splitter and then to the modem (UT Star 300 r2 ) ....

can I know if this would lead to extreme drop isn Signal ? My tel line is faily clear , scratchy only when it rains !

pls advise

thnks

Toolman,

u can log-in the router config. page by typing 192.168.1.1 in internet explorer... it will ask for username & password... Type admin in both fields(its by default)... now a new status page will open... scroll down... there u can see things like snr margin & line attenuation..if ur downstream snr is > 20 then its fine... & line attenuation should be < 20... else get ur line chkd...

hope it helps...

toolman67 · 10-06-08, 08:55 PM

Thnk for the response and I did as directed .... this what wht i was looking for and got
my results as seen on my dsl page is as follows
Snr downstream : 26.8 +/- 2 or 3
Snr Up stream : 18.0 fixed

line attenuation :downstream :37.0 fixed
Up stream : 13.5 fixed

whts is upstream and down stream definations pls ?
I guess my attenuation downstream is not so good and i guess its b'coz my line is scratchy ....

U can see 1st post of this thread to get answers of ur questions...

btw, unless u r facing any problem in ur internet connection nothing should worry u...

Very informative post!

repped you...

Hey,
my SNR ratio is 12.5 upstream ans 15 downstream. Its on the lower side right??
Attenuation is 15.5 and 8.9. This is supposed to be rally great. Right?

Whats the reason for this i.e good attenuation and bad snr, is it common.
BTW i am getting only about 1.5 mb speed during free time. Is this normal.

SNR Margin and Line Attenuation are two different things. The Line ATtenuation in your case is low, probably because your line is freshly laid and has little resistance. SNR Margin is not very bad for you but an improvement will not harm. SNR Margin can be on the lower side due to quality of signal at the exchange.

The attenuation is really low and ideally u should be getting 30+ dB of SNR. Dont know why the modem is displaying 15dB.

Attenuation is dependent upon factors like distance between the modem and the exchange, the amount of cabling being used, the number of nodes and internodes. And both the attenuation and snr are inversely proportional. Low attenuation = high snr and high attenuation = low snr.

Most of the subscribers are getting he speeds which u had mentioned during the night time. Hence there is no need to worry about that.
