Solved Internet connectiom problem

I used to have my cpu hooked up to the internet straight forward but now i moved and i use wireless due to no space near my router. On my settings of internet connection, it wont let me change the setting for wireless. Any ideas to fix this problem? Oh, when i double click the icom, they say i have a VGA PCI 10/100mb ethernet adaptar. Do i need to change that or take it out and dont replace it? Thanks in advance to all responders
