Below mentioned methode will only work with iBall Airway 7.2 18 (lsusb will show it as a huwawei modem)
iBall Airway or similar Huawei Technologies Co., Ltd. E169/E620/E800 HSDPA Modem 3G data cards connecting in Ubuntu.
Using WvDial as backend and Gnome-PPP as frontend
WvDial is a Point-to-Point Protocol dialer: it dials a modem and starts pppd in order to connect to the Internet.
First install WvDial
sudo apt-get install wvdial
sudo apt-get install gnome-ppp
Finally we need to add add WvDial to give regular users the ability to use wvdial to dial a ppp connection.
Using a dialout group
Set up a group called dialout (call the group as prefered) and give members of this group permission to run wvdial as root.
First create the group and add the users to it:
sudo groupadd dialout
sudo gpasswd -a username dialout
Note: You need to logout and log back in for the current user's group list to be updated.
Then set the group and adjust the permissions on wvdial:
sudo chgrp dialout /usr/bin/wvdial
sudo chmod u+s,o= /usr/bin/wvdial
The files should have the following permissions:
$ ls -l /usr/bin/wvdial
-rwsr-x--- 1 root dialout 114368 2005-12-07 19:21 /usr/bin/wvdial
Now plugin your iball Airway device and wait for 15 seconds, then open gnome-ppp from unity dash board
and click setup.
Follow the screen shots to configure Gnome-ppp.
System tray icon of Gnome PPP, after success full connection.
