If possible try to get a modem for 2/3 days from your friend, configure similar settings of your current modem and test it for 2 days or so... then you will be able to come to a conclusion where exactly the problem lies.

hello guys, i am also facing a similar problem, the dsl light seems to go off after being connected for sometime and then it gets glowing again, sometimes the bulb is glowing but i cant connect to the net.The speed has been down for about 15 or 20 days for now its just around 700kbps which used to be around 3mbps.My phone connection seems to work fine all the time.

Well as u said the problem may be in the setup at ur place for the phone and the modem.The wire that comes to the modem should come from the splitter and the re should be no other connection between the splitter and the direct cable that comes from BSNL.Check it .Cos the connection drops when u got a case that the direct cable that comes from BSNL is attended by some other device before the splitter.

thanks for the suggestion, but , i have never altered the connection setup, the main line goes into splitter and from there one line to phone and other to modem. I connect my modem to system with a usb cable. the disconnection problem is mostly during the 2 to 8 am period. it seems to work fine later on.

The upstream an ddownstream values in the modem configuration page seems to have changed. The down stream rate is just 1mbps.Is there any way we can change it.

you cant change downstream.. if it has suddenly changed it could be a temporary issue.. probably they are doing some upgradation work or something

i have noticed the change today only, but the speed problem has been there since 20days.

I am using ubuntu (browser-firefox) and am unable to connect to modem configuration page.
the page gets connected from windows xp. (ie)

Hi,
The upstream and Downstream values keep changing for me. and have no internet for 2 days. At times dsl light is solid but i cant connect the net trough Bridge connection. I am getting error code 678. the internet light in the modem didt glow for last 2 days.

please let me know which one is more stable PPPoe or Bridge connection.

i'd say PPoe is better..

HI as superprash said ppoe is better.But the problem in ur case is not because of the connection type cos unless u get a signal from bsnl both the types will not work.
Hence the error that ur getting 678 saying something like remote server timed out or did not connect ...or something like that is from BSNL end.Hence there is practically nothing that an end used can do to get rid of this error.
It gets generate when the connections exceed the server capacity of BSNL.
Hence the only thing that u can do in such situation is to keep redialing.

I had the same problem but rectified it. here's how i did it
in modem settings(192.168.1.1) in device info in statistics click adsl. if the type is adsl 2 then u shuld change it to G.DMT.
to change it to g.dmt go to advanced setup and click dsl.
uncheck adsl 2 and adsl 2+ and ensure that g.dmt is checked and save.
in management click save and reboot.

i had the same problem( disconnection and then cannot connect for 2 hrs) but this resolved the problem. try it and if it doesn't work then change settings back to normal.
