Thread: BSNL authentication failure

Hello all,

I am in Candolim, Goa. Just got BSNL UL750 last week and it has been nothing but trouble. Frequent disconnections and now having trouble with authentication failures.

This is the error I found on google....

"Error-691 UserID/Password mismatch/problem. In other words this is an authentication failure dueto a wrongly typed userid/password or due to a disabled account (eg; Non-Paymentdisconnection or wrong port-binding)."

(can't post a link coz its my 1st post)

My userID/Password are good and the bill has been paid so it has to be a wrong port binding. Can't get help from support right now. Is there anyway I can fix this problem on my own?

Thanks in advance!

Call BSNL and ask them to change your port. In the mean time, post your SNR and attenuation values.

Hi meetdilip,

Sorry for the late reply. I am on a very slow dialup now. I don't know what BSNL number to call. The numbers that I am trying for BSNL Goa support ( Panjim ) are not working. Bellow are my DSL stats.....

Your number looks fantastic, so there is no line problem, just ask bsnl to change port, & your problem will get solved.

Your attenuation values are poor. Get your line checked. Contact your local exchange and ask for the no of concerned person.

How so? His values are too good!

Mention your modem model make number.
Change mod mode to GDMT
Uncheck Box against ADSL2+
Keep bitswap enabled.
Confirm you use "Dialer" mode
( enter userID/PW in computer window )OR
Always On PPPoE
( UserId/PW stored in Wan page of modem )

attenuation (dB): 32.5. Please correct me if I am wrong.

Looks like I will have to call somebody. Think I will do it in the morning as my brain is about to burst right now.

Thank you all for you replys!!

No problem.
Most of us have learnt the hard way here!

See my stauts page, still I'm getting 1.7 mbps in IDM & 1.5 mbps in uTorrent, Very low disconnection problem, what all u say huh?

How to post reduced size pictures?
I've already posted ADSL stats page,
Why are you asking for my modem/model/make/number etc?
My speedtest results is already in my signature.

How to post reduced size pictures?

depends on the application you use .

Your modem has a
new mod mode " Readsl"
Never came across this kind of mod mode.. That is why modem details were asked !

I am not on unlimited usage plan,
and avatars/signatures etc are all blocked.
The speeds shown in your signature.
Do you update daily ? or old one ?
will it remain constant for days ?
