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?

you will find client Tr_069 disable it.
3. Alsom "SOAP"

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:

1. My user id is already entered without any domain name suffix.

2. I have entered the open DNS addresses and am currently testing the link stability.

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.

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