*sigh* You realize when you say "I downloaded this..." without providing what "this" is is pretty useless for us to help you troubleshoot?
What update WERE you on before you started modifying the phone?
What did you download and install?
What modem / baseband version is installed?
Wifi and phone functions are most likely not working because you either downloaded the wrong thing or didn't follow the installation instructions correctly. Typically this would be because of mismatched modem and kernel or there's a patch that needs to be installed.
Usually I would just say install the newest stock firmware (4.4.2) through Odin, but depending on what update the phone had originally and if you plan on continuing to customize your phone, it might be better to stick on an older system as the newer ones really lock down the ATT version.
Long story short: Help us help you. Provide ALL the details about what's going on and we can probably get you fixed up easily enough.
