Thanks Thomas !!!
Following algorithm "mostly" works ::
##############################################################
a)
Check whether the required bearer already exists, via ::
mmcli -m 0 --list-bearers
mmcli -b /path/of/bearer/as/returned/by/above/command
If yes, then go to step c).
b)
mmcli -m 0 --create-bearer="apn=airtelgprs.com"
c)
mmcli -m 0 --simple-connect="apn=airtelgprs.com"
d)
dhclient -r wwan0
dhclient wwan0
##############################################################
In everything goes right, then telnet/ping work fine.
In the beginning, I said "mostly", because the last step (dhclient wwan0)
hangs 8/10 times. Whenever this happens, the only remedy that I have found
so far is rebooting the machine.
Is there a saner way to have the "dhclient wwan0" work fine every time?
Thanks and Regards,
Ajay
