for some reason I cannot get my Wireless Card to become active but in device
manager it states that it is working properly. I try to turn on wireless
activity via my laptop and it shows activity but no go!! Upon my recent
install I did not need my wireless network until I just recently tried to use
it.

should just do another reinstall??
