Question At&t stock korean por issue [help]

There are 2 stock KOREAN PORTS for our device the LG optimus G e970, my issue is that people say to use the JB RADIO, when i use it , i don't get any sound on my rom nor have Bluetooth or WIFI or cellular network, then i proceed to use the hybrid radios they work for me, have everything working except WIFI.

anyone that has WIFI working that can tell me what radio you're using so that i may get wifi to work. Thanks in advance
