Hi guys

For the last 1 week, I am facing lot of trouble with my BSNL broadband connectivity (with Huawei SmartAX MT880).
It connects like before, but once connected it just disconnects within a minute. And then so forth and so on.. it keeps cycling through connect-disconnect.

I read through forum msgs for similar problems but cant make out for sure whether its to do with the quality of line (bsnl phone line) or the modem settings.

I tried to capture the SNR values of my connection, which are:
Model Name MT880 Firmware Version V200R001C01B021SP02 INDIA
May 17 2005 ADSL Line Status ADSL State Show Time
Data Path Interleave
DSP Version D.57.2.17 Operation Mode ADSL2
Output Power 12.1 dB
Upstream DownStream ADSL Link Speed 861 Kbps
ADSL Link Speed 7562 Kbps
Previous Tx-Rate 861 Kbps
Previous Rx-Rate 7603 Kbps
SNR 10.4 dB
SNR 6.5 dB
CRC 0
CRC 0
Attenuation 8.0 dB
Attenuation 17.0 dB
FEC 0
FEC 0
HEC(ATM Layer) 0
HEC(ATM Layer) 0

Dont know if you can see the above snapshot, so copying it in plain text too:
Upstream
---------
ADSL Link Speed 861 Kbps
Previous Tx-Rate 861 Kbps
SNR 10.4 dB
CRC 0
Attenuation 8.0 dB
FEC 0
HEC(ATM Layer) 0

Downstream
--------------
ADSL Link Speed 7562 Kbps
Previous Tx-Rate 7603 Kbps
SNR 6.5 dB
CRC 0
Attenuation 17.0 dB
FEC 0
HEC(ATM Layer) 0

I read somewhere that selecting G.dmt instead of ADSL2 is better for connectivity, but in my config pages of MT880, I cant find anywhere to select G.dmt etc.

BTW, I have had this bsnl connection (at the current location) for the last 2.5 years and havnt really faced such a problem earlier. The connectivity has been more or less stable.

Can someone suggest, future course of action:
- Should I complain to BSNL for quality of line?
- Should I request BSNL to reset my port (read somewhere on a forum ; no idea what it means?
- Should I upgrade my modem FW?
- Any clue on how to select G.dmt on MT880 (any hidden means)

BTW, I dont have parallel phone connections before the modem and I even tried to remove the splitter and connect the phone line directly into modem to no avail.

Thanks for your help in advance

1.Get your line checked. Ask the line man give a new line from junction box to your home.

2. Check the splitter. Make sure that all connections come only after splitter.



3. Bypass the splitter and connect the line directly to the modem and check.

4. Check your power adapter. May be it is faulty.

5. If possible get another modem from your friend and check it at your place.
 
Guys,

Booked a complaint with BSNL, but apart from 2-3 calls from them to re-check if the problem is resolved, no real action.

Meanwhile, I tried borrowing a friend's modem (UT StarCom's ut300R2u) to plug into my line and check, and find that it seems to get consistently higher SNR value (specially for Upstream) than mine, and in the little time that I could test, I didnt see a disconnection using the same.
FYI, for me SNR for upstream/ downstream were: 10.4 and 6.5 dB averagely.
While for my friends, similar values were: 16.7 and 6.8 odd.

Still not sure, if this confirms that the problem is with my modem or the line or both?

BTW, for my modem, there are sometimes, when the connection lasts even 2 hours or more, but then for most of the time it keeps connecting/ disconnecting.

Your suggestions/ help here is appreciated.
Thx
Sandeep
