hi...everyone..

I am facing very problem in bb conection.
I have a 750home UL - 512kbps plan runnning bsnl type 2 adsl2+ cpe/ide modem connected to a line through a splitter.

I am facing very freq. disconnection problem in the connection (mainly during 7am-2pm, daily)

Here are my speed test results.

Your attenuation values are too high. This is probably the reason for the frequent disconnects. See if you can change your modem mode to G.DMT for stabler connects.

i cant see where can i do that. i have been told that i have to uncheck the adsl2+ option in dsl menu in login page.
but i cant find it where it is. and what is GDMT.

I have menu name "DSL MENU"
Under that i have 2 submenus namely;
Management server
CWM Parameters.

Open your modem's login page, go to wan settings, you may have to click edit, there look for something like "mode", in mode uncheck adsl2+ option, leaving G.DMT enabled. I don't know the exact steps for your device, as I am not familiar with it, but the above mentioned method should be the same more or less, with a few changes here and there.Also, I remember you having noise in your line, if so, get the wiring checked.

nope i dont see a wan option newhere in my login page...

nw i finally did change to g.dmt from adsltwoplus-auto mode.
the option wasnt in wan but was in internet connection>adsl>basic attributes.....

but on changing the mode......my snr value horribly dropped to 7db & 0db.
now its stable between 16.5db (down)

whenever i try to download something from internet (mediafire) from IDM...
it goes fine but after a 2-3min the connection gets disconnected. this is horrible to experience lyk dis.

I used to have a SNR value between 35 to 38.5 db (down)
and also attenuation didnt changed a bit. in the day it was 35db and now its 31.1db (down)

If that is the case, then it seems like a line issue. How old is your line ?

i have a copper line (which is kind of flexible, a bit more than the usual- if that matters.). the pole that m connected to is just by my home. and the wiring is 6 months old.the wiring goes straight to my room to an adsl splitter. no cuts or joints.also i have a internal wiring in my home (5yrs old) but im not using that. though it has a point to connect any phone line outside my house near the pole but have twist the wire in the internal wiring.there is no use of changing to mode to gdmt. not a single value drop in attenuation also snr value keeps changing freq and its not above 30 now.still the same thing goingalso have apllied the tcp/ip optimizer tweak too.

tho using a mixed dns...is not an issue to get freq disconnections. m i right???

----------

the dns client and dns relay servers are the same in the login page as bsnl's defaults like 218.248.255.197/194
