[CentOS] very new user having problems

I just loaded CentOS and want to connect to the internet using a radio and 
wireless internet.

I got some numbers from the internet provider.  He walked me through some of 
the changes in the networking area.  But it did not work.

I have read three books on Unix and I am determined to do this. but I think 
I need lots of help.

Where could I look this up on a windows machine??

when I get connected to the net,  then I  have another question about how to 
make the jave download operational.



thank you
