Welcome to LQ!!
First let's see if the Wireless card is being detected. Open a terminal and run these commands:
sudo ifconfig -a
(look for a device like wlan0 or maybe eth1. Normally, the standard ethernet (wired) connection will be eth0)
(look for two different network devices--one standard ethernet, the other wireless)
sudo dmesg|grep keyword
(replace "keyword" with something relevant from the lspci output)
If the wireless device (on the computer) is found in lspci, but NOT in ifconfig or dmesg, then it means you need to install a driver.
One way or the other, we need to know the details of both ends of your wireless internet setup---ie what is in the computer, and what is used for the access point.
Also, I tried to re-install the vodem ISP CD installer but it can't read the content.
That presumably is a setup disk for Windows--it's not going to work on Linux.
