It is very easy to setup a wireless internet connection using your Reliance or Tata Indicom DataCard on your Ubuntu running PC. I’ve myself faced a lot of problems and finally here I am with a well-researched solution. I’ll try to simplify it as much as I can but it is not an easy job. Its going to be a little scary, but don’t lose hope and try finishing steps 1 to 6. Now start following the steps :
Step 1 : (Optional) I’ll strongly recommend you to upgrade your Ubuntu to latest Ubuntu 9.10. If you have not done it yet, I assure you that this will make your life much easier.
Step 2: Download the package ‘wvdial’. If you have an internet connection (may be DSL on ubuntu), execute the following command :
sudo apt-get install wvdial
However, if you can’t connect your Ubuntu PC to internet for some reason then you’d have to install wvdial manually. This may take some of your time, patience and skill. Refer this article.
After you’ve downloaded and installed wvdial, tighten your seat-belts because its going to be a hell of a ride now!
Step 3 (Don’t Panic!): Now, plug in your Reliance or Tata Indicom data card into one of your USB slots.
TARGET : Determine the name of the port you connected it to. Seems easy, doesn’t it? You’ll see …
There are 3 ways to do that – (a),(b) and (c). Start with (a) and go to the next one only if the previous one fails.
