Wifi won't connect

[benjasher]

I just installed Siduction Shine-On Xfce on a Dell Inspiron laptop my father-in-law no longer uses. The installation went smoothly except I cannot connect to wifi to finish the install. I have done the rtfm thing, used the network configuration tool and everything else. I even did a search on here for anyone else having the same problem.
I use T-mobile wifi here at the house, if that makes a difference.
Any help would be appreciated.

Does that Inspiron have a hardware RF switch?
