Solutions for linux networking problems

For more information about linux networking solutions-General Linux technology-Linux technology and application, see the following. Not long ago I installed ubuntu12.04 and found that linux is still very good. I plan to take a look at it for a while.
However, I found a difficult problem, that is, the problem of networking. I spent most of my time in school. the network in the school is wireless network. the specific process is as follows: first connect the computer to the wireless network provided by the school (this network cannot be used directly, after the connection, if you want to access the Internet, you must have an account password provided by the school, and this account password can only be applied by the teacher. Otherwise, it will only be connected, and there is no real effect ), then open the client provided by the network supplier, such as the telecom flash client and the mobile casual client (I use this client, which seems to be specially customized, which is quite different from what I find on the Internet ), enter the account password provided by the supplier (of course, only the network fee is paid), and connect to the account.

The key to the problem is that this client is basically for windows. if you want to run this client to access the internet, what should you do? By the way, I tried the wine software and found that, after clicking Install, the casually executed exe did not respond, and nothing happened.
