Dear Group members:-

i am trying to configure the 3G-module.i have inserted my sim card into the HWIC module sim card properly working in the phone and i am accessing the internet.
but when i configure HWIC module accordingly i am unable to access the internet my configration pasted below if any experience person guid me little.

in my phone i just put APN and it work fine without Authentication Service provider ask me that the username and password is blank.. and no authentication.

You have missed the Dialer interface... the Cell0/1/0 interface needs to be looked like a modem... so you need a dialer interface. I also noticed in your Chat-script up i have ATDT*99, were I use 98, not sure if that maters or not.

Now you carrier might register your SIM to the SN, or (EIME, MEIE, IEME whatever it is) so the SIM might not come up on the network when switching it to a differant hardware for data traffic. I have this issue with AT&T often.

Anyway here is a config similar to yours that I use often:

As you can see you default to the dialer interface not the cell interface. the Dialer acts as the middle man determining when the cell should make the connection and when not. As you see I have mine set to be up all the time with the "Dialer persistent" cammand. if using this as a back up data connection you will want to use on demand dialing with a acl.... keeping the connection up all the time even not passing traffic, just in a idle state, will take you over you contracted 5Gig bandwidth. It is not realy unlimited data, so read the fine print. I think Sprint has a true unlimited plan for this use, but the odds of having service is about as commen as everyone having a lake front home...

Good luck..

Dave

P.S. I just noticed you are not using US cell service so just ignore my carrier specific comments... use your APN not what I have listed...

Hi,

the cellular interface works already as a dialer interface.

You can configure a dialer interface over it for specific requirements, but for a normal setup this is not required.

Can you please enable:

debug chat

debug dialer

debug ppp nego

Then start a ping traffic that will raise the cellular interface, and collect the logs.

I've seen sometimes that even if the ISP does not require authentication, we need to configure dummy username/password to succeed.

I'd suggest you try this:

1. capture the debugs with the current config

2. change the profile to add authentication chap and username/password guest

3. change the cellular configure to add "ppp chap hostname guest" and "ppp chap password guest"

4. collect the debugs again.

Cheers

Marco
