Your default route doesn't make much sense given your IP & netmask.
Neither do the DNS servers.

what???? did you see my picture ???? i attached???

yes

what else would I base the comment on?

Yes...did you not understand the reply??

The default gateway doesn't make sense with that IP address, nor do the DNS servers. So either you put in the wrong information, or you've not got something set up right. I'm assuming this is a follow-up from your other threads about your GSM modem, where you didn't bother posting a reply, or acknowledging you even got answers.

look... i tried to connect using MOBILE BROADBAND....i have given the right configuration so that led to the result that the connection is active.but i cant browse??? what should i do? please help me!

No, you have NOT given the right information. If you did, it would be working.

You need to contact your ISP, and ask them what the default gateway and DNS information should be, and set it up accordingly.

i just know only the APN ... so i setup only that field in MOBILE BROADBAND

ok.....
can u check about the wvdial section please?

...which explains why it's not working. Since you did NOT PUT IN THE RIGHT INFORMATION. Again, get the correct information from your provider.

Spell out your words. And check WHAT about the wvdial section?

what informations should i know from the provider brother ? :(

If that network set-up is the result of a DHCP lease
you need to contact your ISP and ask them to sort
their stuff out.

no.not useful.i am expecting another answer please.

any body help me.

If it works from Windows, I suggest that you boot into windows. Bring up the mobile broadband device and surf the internet to make sure it is working.

Then go to a dos prompt and provide the output of:
