Please post your line statistics so that we can look into the SNR and Attenuation details. A screen shot of the page would suffice..

i just wanted to inform u dat my connection had gone just now but den i reconfigured it to bridge mode.it is working now although for sometime.............
here's ur img its for da pppoe config.............

I think your LAN IP is creating some problem, try to manually assign them to do that follow these steps

-- Go to control panel
-- click on my network connection
-- then select your network probably your LAN connection
-- right click on it and select prop.
-- Double click on TCP/IP on that same page
-- then select use the following ip address then enter the numbers as follows

ip address: 192.168.1.(any number b/w 2 and 254)
Subnet mask: just press tab it will be filled with 255.255.255.0
Default gateway: 192.168.1.1

Primary DNS: 208.67.220.220
Sec. DNS: 208.67.222.222

And yes btw whats the service name you are providing when you are creating a pppoe connection??

@adhirajb12 I just looked at the screenshot. The line parameters all look fine. Even u have configured your modem to work in G.DMT. I guess the problem which u are facing might be of the temporary nature due to some work in the exchange.

BTW, have u set the DNS address in the router?

Your Line attn 41 db is high. ( for D/L)
Check how you have connected the Adsl splitter.
Exchange port Rj11==LINE port ====>>
Modem Port Rj11 to modem
PHONE PORT ===>>> ALL phones.
Check for bad contacts. Use short cable to modem .

Probably your location is about 4 to 6Km from your exchange. Confirm.

adsl splitter is fine......
if u r asking about the nearest telephone exchange office, its about 2 kms off....
but the lenght of my telephone wires from the box is may be about 500m

If it is possible try reducing the amount of wires being employed for setting up the connection. ADSL signals are largely attenuated as the length of the lines extents. The shorter the wirings, the lesser the attenuation.

The attenuation of 41dB is expected. U must be precisely 3kms away from your exchange according to ::. Kitz - Max speed calculator .::

So i dont think u can do anything more to decrease the attenuation..

Presume 500Meters is from the telephone pole to your house.
Is the phone connection very old or new ?
IS it a Black Box with screws to connect the telephone/
Or a Yellow box with a RJ11 Port ? ( with some PCB condenser etc inside ). ?

one more prob........
i was using it in bridge mode, thought it would end my prob.but after shutdown i started it again at 5.30pm and when tryin to connect the dial up it said connecting through WAN pppoe and then showed remote computer didnt respond...

i had to reconfig again to start it............
plz help.........
it is noteworthy dat my lines have been fixed only a week ago... i made them install new cables......but still y probs are not gone

Connecting through Wan Miniport error occurs when they have disconnected u from the exchange for some maintenance works. Dont worry it might fix by itself..

do i hav to do what u have told me in para 2 of post #2 after all the troubleshooting u hav done........
setting that are seen are enabled: g.dmt, g.lite, t1.413, adsl 2, annex l, adsl 2+,
disabled: annex m, sra...
wat shuld i do.............

is da thing told by post #7 needed to be done.......................
plz help....

BSNL works on G.DMT adsl modulation.

In your modem u have enabled g.dmt, g.lite, t1.413, adsl 2, annex l, adsl 2+. Yet the modem status page is displaying the the modem is syncing with the exchange at G.DMT

U can experiment with the connection by unchecking the other adsl modulations, it is worth a try to reduce the attenuation..

1.Presume you selected "bridged" in this page.

2.Check Diagnostics page. report only FAIL components.

3.Start/ RUN cmd type ipconfig /all
post details again.

Yes try T413. or ADSL2 Un check GDMT

i dare not until of ur advice as i don know what these technical terms means

U can know the details of those terms in Wikipedia, the free encyclopedia Try searching for them over there.

Just open 192.168.1.1/main.html
admin admin

BREAK: TEA!

im currently on bridge mode and its working properly for quite some time,i wud like to continue on this mode but dont know any drawbacks of this if there is any relative to pppoe.....

it wud be of great help if u shed some light on it.....

also wud there be any problem occuring during the download from 2-8am time period. i mean does the dial up disconnect when the dsl is down for some time....dis ofcourse does not occur in pppoe.....

plz help

Kindly checkout Bridge versus Router Mode Differences, Advantages and Applications

The connection will get disconnected no matter whether u are in bridged or pppoe mode, if there is something fundamentally wrong.

no i mean sometimes my link goes down n comes again (at 5am approx) after sometime.........
as soon as it cmes back da pppoe the download resumes again, wud this be possible for bridge too.......

Yes, if u schedule the script to reconnect every 10 minutes. If the connection is already present, the effect of script will be nullified. But if the connection is absent, the connection will be reactivated withing 10 mins..

i guess this is what you are talking.. Prashanth Speaks-Technology and Life: How To Schedule A Connection When In Bridged Mode step 2.. schedule it to run periodically
