Wvdial is the most used utility used from linux to configure wireless modems. Unfortunatly it doesnt come preloaded on Ubuntu 9.04.
This note refers to Ubuntu 9.04 running on a PC that has no access to the internet via LAN or WiFi and the modem we have is not recognized by the system (like many 3G CDMA or HSPA modems).
So this is a strange and difficult case!
At first I downloaded the following packages (from a pc connected to the internet, any O.S.):
Note that above are all for an i386 pc.
I down loaded all on my xp OS, and then paste them to the ubuntu 9.04 after mounting my xp drive into /var/cache/apt/archives/ directory using sudo nautilus from terminal. Then I installed all packages by double clicking each icon (of .deb package) in above order (1,2,3,4 and finally 5). I ignored all informative messages. Finally I had to run wvdialconf, edit the /etc/wvdial.conf file and be connected with sudo wvdial.
To see what all entries i gave on wvdialconf to get it configured for tata indicom plug to surf...see my other post.
