Error while configuring LAVA 720G data card
I recntly purchased LAVA 720G data card [in for form a USB dongle]. After attaching card to the laptop I tried the following:
Code:
[sudeep@myhost ~]$ lsusb

and then, after a little digging, I tried:
Code:
modprobe cdc_acm
modprobe usbserial vendor=0x1c9e product=0x9605
then,
Code:
[root@myhost etc]# ls /dev/ttyUSB*
/dev/ttyUSB0 /dev/ttyUSB1 /dev/ttyUSB2
and,
Code:
[root@myhost etc]# wvdial bsnl
--> Sending: ATDT*99#
--> Waiting for carrier.
ATDT*99#

So as you can see, I cannot connect to internet. What could be the problem? |
