Windows 7 Error 31 While Trying to Use Windows Dialer for 3G Dial Up Connection

[rak007]

I am not able to connect to BSNL 3G using standard windows dialer and not even through CiDial but only working through Mobile partner. I had faced this earlier but that was another machine, another OS.
It stops at the verifying password screen and then immediately disconnects and again attempts to reconnect but does not connect.
Any idea why something like this happen ??
I always give some random values in id and password as they are anyways irrelevant.
This is the error i get when trying to connect using standard windows dialer

I can perfectly connect using Mobile partner but nothing else

Further to this i found few more things. May be this will help you guys to pinpoint the actual problem.

If i keep the setting as follows where under connection type is RAS Modem (no clue what this is)
PS: In below screenshot assume the connection type is set to RAS Modem

And when i try connecting to internet using mobile partner i get error as

But when in the same settings, it is NDIS (i dont know this either) it works fine and you see that the error message is same as what i get when i use normal windows dialer.

So now anyone can tell me what the issue is ??

It seems like you are facing connectivity issues with BSNL 3G when trying to connect through the standard Windows dialer, but it works fine when using Mobile Partner. The error you provided indicates that the connection stops at the verifying password screen and then immediately disconnects without establishing a connection. Based on the information you provided, here are a few possible reasons and solutions: 1. Connection Type Issue: - The connection type settings play a crucial role in establishing a successful connection. When the connection type is set to "RAS Modem" (Remote Access Service Modem), you encounter the issue where the connection fails both in the standard Windows dialer and Mobile Partner. - On the other hand, when the connection type is set to "NDIS" (Network Driver Interface Specification), the connection works fine through Mobile Partner, but you still face the same issue with the standard Windows dialer. 2. Configuration Mismatch: - The mismatch between the connection type set on the device and the configuration on the network side might be causing the disconnect issue. - Ensure that the settings on your computer match the requirements of the BSNL network for a successful connection. Sometimes, different connection types might require specific settings to be configured correctly. 3. Authentication Issues: - Since you mentioned using random values for the ID and password, it's possible that incorrect or random values are causing the authentication process to fail. - Try using the correct login credentials provided by BSNL to ensure a secure and stable connection. 4. Software Compatibility: - The software you are using (Mobile Partner) might have built-in configurations that work well with the BSNL network compared to the standard Windows dialer. - Ensure that the necessary drivers and software components are up to date for proper functionality with the BSNL 3G network. Given the information provided, the issue could be related to the configuration mismatch, authentication problems, or compatibility issues with the network settings. It would be beneficial to ensure that the settings on your computer match the requirements of the BSNL network and that correct login credentials are used for authentication. Additionally, updating software and drivers related to the 3G modem might also help resolve the connectivity issue.
