how do access internet from netconnect+ modem on openSUSE

nibiran · May 28, 2012, 6:50am

Hey Folks,
I was able to connect to the internet on openSUSE 11.3 using my Reliance data card having model EC159.
However when I decided to upgrade to 12.3, the installation went fine and was able to work on the OS albeit an internet connection.
I have tried to troubleshoot with the steps known to me. The steps are:

lsusb (able to detect the data card)
modprobe usbserial vendorid productid
Configure wvdial.conf
tried to connect to the net but i get the message
wvdial: unable to connect to /dev/ttyUSB0
Please help me resolve this problem.

Your help would be appreciated

With Regards
Nibiran

wvdial cannot connect, since /dev/ttyUSB0, which it wants to use to establish the connection, simply isn’t there.

Take the device from the USB connector, reconnect, and immediately afterwards do


dmesg | tail -20

and post the output here, between CODE tags, otherwise it will be hard to read.
