Wireless network settings

Location of my settings problem:

Start > my computer (right mouse click) > properties > hardware > device
manager > network adapters > Intel(R) PROWireless 2200BG Network Connection

When I follow the above directions and then select (right mouse click)
"Properties" for the mentioned Network Connection and then choose the
"Advanced" Tab, there is a check box labelled "Wireless device off (radio
off)". This check box should be unchecked, but everytime I shut down my
computer it is checked again the next time I start up my machine. My
computer then will not receive my wireless routers' signal until I go through
the entire process described above - very annoying...

Can someone help me? Thank you so much.
