Default [SOLVED] HELP!! Wifi won't work after root!!!

Hello, I finally decided to root my SCH-I545 ... all went well then all of a sudden this morning my wifi wouldn't turn on. Come to find out that wpa_supplicant.conf is missing. I don't know what to do!!!! I've always come here first for my problems and I couldn't find anything! Please help! Thanks in advance!

Edit:
In the build.prop file, I noticed that ro.wifi.channels was blank. Thanks Again!
Edit:
No one replied so I decided to flash to factory.
