Thread: Internet going off every 2 minutes.

I am in Kolkata using the UL 750 Plan. My router is Nokia Siemens residential router 1600.

Data from router is :

Downstream Upstream
Rate (Kbps) 10483 839
SNR Margin (dB) 21.2 13.6
Attenuation (dB) 11.0 5.7
Attainable Rate (Kbps): 14251 1199
Output Power (dBm) 12.4 15.7
Super Frames 29842 30317
Super Frame Errors 493 78

My usual SNR for downstream is far lower, about 10...this is not representative of the usual state. All other stats are same as average.

Now my problem is sometimes the SNR for downstream goes down very low to about 2 or 3. A few seconds after this the line goes down and starts to reconnect and after reconnecting it will usually keep disconnecting and reconnecting several times before becoming stable.

The DSL and Internet LEDs keep blinking or go off if this happens and never stay on properly. The status LED goes off after blinking sometimes and then starts blinking again and goes off, when it stops going off the router stabilizes.

I have tried

1 ) Bypassing the splitter
2 ) Trying GDMT

None of these worked.

The error keeps happening very often , sometimes once per 2 minutes or such...other times I get maximum half an hour of stable internet. This makes using the net very difficult and causes much annoyance. Is there anything for me to do except complain about the line because the fault is at BSNL's end ?

P.S. The wiring is likely not a problem. My current config is having the main line come into a room , where there's the splitter and phone, from where I connect the splitter to the router in the next room through a long RJ11 going along the wall. I thought this might be a problem, but as I said I directly connected the line to the router and the same problem happened.

i too had the same problem.... i registered a complaint.. bsnl guys came and checked my modem and they said evrthng is fine and it must be due to ageing of modem... i was really annoted... but after a month the problem got solved automatically... anyway u register a complaint

I feel it is a case of wrong configuration by BSNL Kolkata. It is meaningless to set at 10Mbps and odd(as shown by Gigit) for UL750 connection and the customer is put to suffering.
Had they set it to standard 512Kbps , it would have worked stably.

It is better that Digit approaches the DE in-charge of his section with a copy of this data put up by him and request for reconfiguring the server to the presently permitted standard for UL750 plan.

I had same problem,I lodge a complaint,they checked my line,and now all set and I here's my stat.

Done registering a complaint under "other". They said they'll make a call . Hasn't happened yet, I'll let you know if they do.

None of these worked.

1.
Check whether Bitswap is enabled .
2.
Disable Client TR_069/SNMP option if seen.
3.
IN DNS enter google 8.8.8.8 and 208.67.220.220.
4.
Confirm , whether you have connected ALL phones
to the PHONE port of the ADSL splitter.
5.
If for an extension phone , not possible use additional
ADSL splitter. ( not more than 3 or 4 phones )
6.
Broadband connection, is always direct ( with/ without adsl splitter)

1. Yeah.
2. Where ?
3. I don't use BSNL DNS, I go for google. I use 8.8.4.4 and 8.8.8.8. at this moment. Would switching the first help ?
4. Yeah.
5. 1 phone
6. Oh. I just thought that the splitter --> router line was doing poorly and/or the splitter was not separating phone and router signals properly to cause low SNR.

My router is Nokia Siemens residential router 1600.

2.Disable Client TR_069/SNMP option if seen.
2. Where ?

See under Management menu in modem/router.
wait....

2. Disable Client TR-069
Check under Management menu in modem/router.

What next ?!!!!

@ Digit

Post a screen shot of your router of your modem menu page.

OK, here we go to answer the queries

Secondly, yes, I'm on PPPoE mode. The other types available are PPPoA, MER, IPoA, Bridge. What do you think I should go for ?

hii frnz.. my dsl goes n comes back often... its happening again n again,,,, plzzz tel wit 2 do m waiting for u alll

Better is to lodge a complaint with bsnl and let them come and check the cable and router.

@coolzee

post you SNR and attenuation values here.
