Hi,

I've been using my BSNL boadband connection for the last 5 years (yes, even before DataOne started, using the DIAS service). Its been excellent until 1 month back when I suddenly started experiencing frequent disconnection. Any time of day, the connection is on for about 4-5 mins, then drops for 3-4 mins, on for a few mins, off again, etc, etc. When the line drops the modem's ADSL LED goes off. I have complained to BSNL several times, they checked the line twice, said it was fine. They tested my modem (BSNL-supplied Huwawei WA1003A) at the exchange and said maybe its faulty, advised me to replace it. I replaced it with a TP-Link W8910G ADSL modem + wireless router that I bought outside, but the problem continues. I wasted money on it for nothing.

My SNR seems fine, ie, 30-31 db downloading and 12 uploading. Attenuation 12 downstream, 3 upstream.

Attainable Rate (Kbps): 8960 down 512 up
Rate (Kbps): 2048 down 480 up

I'm connected in PPPoE mode, always on. I've got G.Dmt, G.lite, T1.413, ADSL2, AnnexL and ADSL2+ all enabled in my modulation setup.

I've checked all connection points and cables inside my house, and they're all fine. No oxidising, nothing. The modem is located from any other device that might interfere with signals. I tried connecting the modem directly to the telephone pair, without the splitter, and phone completely disconnected. The problem persists.

The LAN connection between my PC and the modem is fine. Its only the DSL line that keeps going down.

I'm totally confused, and the BSNL support technicians' technical knowledge seem to be extremely superficial. Can anyone help me with any analysis or suggestions, please?

1. Disable adsl2 +
2. In management or maintenence
you will find client Tr_069 disable it.
3. Alsom "SOAP"
messages disable.
4. if you are experienced you can try Fw update
recommended by the company.
firmware upgrade 1st june 2009
http://www.tp-link.com.au/support/do...?a=1&m=TD-W895.
5.Confirm how you connect "Dialer" mode or "Always On' mode.

6. Post ipconfig /all data
Start run type cmd type ipconfig /all

Forgot to add - my connection is ALWAYS ON. I have configured the userid/password in the modem for the convenience of the other users at home.

Also, I don't recall seeing a screen where I could configure SOAP, but I'll check tonight.

does the power LED blink when the ADSL light goes off?

No, the power LED remains on, as normal. The LAN connection with the PC also remains on. Only the ADSL light goes off when the broadband connection is dropped, and comes back on when the connection is restored.

Hi Essbebe,

Thanks for your suggestions. They have not changed the status, unfortunately, ie, the connection still drops as it did earlier.

Here's my feedback from each recommendation:

1. ADSL2+ disabled

2. TR_069 was already disabled.

3. SOAP - could not find this option in any modem menu

4. Latest firmware downloaded and applied successfully.

5. "Always On" mode

6. ipconfig o/p:

The problem still persists!

Is there anything further I can try? I appreciate your suggestions.

As a further update, I also tried switching to Dialup mode after updating the firmware and the other changes, but this did not solve the problem, so I've switched back to "Always On" mode again.

TRY:
1.
Enter user id without @ bsnl.in.

2.
Try open DNS:

Can you post the screen shot of your modem/router
showing
SNR Attn line speed and mod selected.

Also Device status page, ( with menu list )
for comparison with other
known familiar modem/routers.

Here they are. By the way, the situation remained the same with Open DNS, so I have reverted to auto DNS.

I am doing this between line drops.

ghoulish · 07-07-09, 01:50 AM

Here is the bottom half of the modem status screen which is not visible in modem1.jpg.

ghoulish · 07-07-09, 01:55 AM

Here is the modem status page when the connection is lost.

ghoulish · 07-07-09, 01:59 AM

Here's something that puzzled me: when I first took the modem snapshot (modem1.jpg), the very first line says ADSL2 mode.

Now, after the last disconnection/reconnection cycle the same line says T1.413 mode (see attached pic). Is this significant?

ashok26 · 07-07-09, 08:26 AM

i have the same problem from one month.
that is DSL line problem which is due to havey winds even tiny winds also they interrupt weak telephone line connection.
the bsnl officer offered me to change connection wire which has lot of bugs in it.
i suggest you may do the same.
hopeful you can get out of the problem.

essbebe · 07-07-09, 08:35 AM

@goulish
Normal.
Probably in "MOD mode" box selected as Auto.

Your modem/router/wifi appears almost same as WA3002-G4 ,
Beetel 450Bx Siemens ,sl2-141 etc. DNA 211-I etc.

Please summarise latest position. Thank you.

ghoulish · 07-07-09, 06:40 PM

Hi essbebe.

Status is exactly the same, no change, no improvement. BSNL also changed the port at the exchange but the problem remains.

I've now got them to agree to inspect and test the line side again properly. Lets see if they do a good job. I'm willing to give them a chance.

After all, its only the second problem I'm facing in 5 years of excellent reliability. But each time there's a problem one has to be ready to run from pillar to post in person. All their call centers, contact numbers, email id's, online chat, web-based feedback, whatever...........they are just for providing employment, not service. If one is willing to spare tons of patience the only option is to interact with the technicians at the exchange.

I'm keeping my fingers crossed, but in the meantime I'm still open to hearing everyone's suggestions to try in parallel.

Hi ashok26. At this point I tend to agree with you. In the beginning I just went to BSNL with an open mind. They first checked for line faults and gave the all-clear. Last few days I've been focussing on the electronics, but after the combined actions and inputs of the BSNL broadband guys and the experts at this forum I am satisfied that it is not a settings fault and that it is the line that is at fault. Come to think of it we are suspecting a lot of very mature electronics vs line equipment that looks so aged, untidily done and technically unchanged for several decades. These lines are much more prone to damage from air, wind and water than the electronics which are located within concrete walls and powered by UPS!

in your 2nd pic under DSL settings uncheck all other options except G.dmt enabled & apply & reboot modem.

Hi whitestar.......I tried this yesterday and I tried it again just now. It didn't work, ie, I still have the disconnection problem. Thanks.

07-08-09, 11:39 AM

Last couple of days i am facing the problem of frequent disconnection also SNR value is not stable (sometimes high but within a hour it's become very low).
From yesterday night I was not able to connect internet error 678 always giving.After lots of try finally I able to connect once in today morning. Is it totally line problem ?

Ghoulish,

I am using BSNL BB for past 2 years last 22 months it was fine and excellent later even I had a same pblm as yours like there were frequent disconnections in ADSL link and almost like a months time BSNL folks did not detect the fault. later aomething striked in my mind that there could be some pplm in the service cable that runs from Pole (junction box) to or inside your room. As a result I caught some line men and bribed him some 100 buks and asked him to replace my service line and you know the service line had 4 joints as a result of which there was an earthing pblm especially during rain. and there was a huge signal loss from 4 of these joints.

We are suppose to get 10 ohms till the splitter for the BB to function correctly I was getting 4 ohms due to loss in the signal from the service cable.

Now all my cable is replaced with NO joints in the midst as a result MY CONNECTION IS NOW ROCK STEADY.

Hence I would suggest you to check your physical line which is more and very imp for unintrupted reception of BB service.

Hope this helps.

Mukund33,

Thanks, you may be right, and I will try talking to the linesman direct. The line into my house does have at least 3 angular turns in it around corners, etc, so its possible that I may be facing the same root cause. I was a bit suspicious about this problem happening around the same time as the monsoon season.

regards
