update:-..
and in some situation depicted like below(please read the comment from Mr.Rajn), you can connect to the internet, but it may not possible to surf the web. Mr.Rajn kindly provided a solution for such situations
—————————————————————————————————
if one runs dmesg it gives long repeated list of dropped connections such as in=out=0…dest=53, IP add and dns address…etc.
Usually this means you have a firewall which is not allowing this connection.

Most Mandriva come configured with firewall called Shorewall (and is not known to everyone). Usually Shorewall is configured for net and local interfaces. For example in my case net was configured for eth0 while local was configured for lan0. This was because while at home I would connect to internet using a cable box which also served as wireless router. Hence the two choices.
However, while traveling, I had to purchase MBLAZE for connecting to net. And therefore, I had to change /etc/Shorewall/interface by adding the following after becoming superuser
net ppp0 –

save
reboot and
now you are all set.
