Highly recommend you use a wired (cable) connection when you are broadcasting (streaming). This wireless internet is susceptible to interference from devices like cellphones, microwaves, and various other devices.
Also your WiFi Router will decrease your internet conection speed, This can cause you to loose packets when streaming leading to skipping or buffering of your radio show which results in listeners being lost. It is much better to use a wired connection to avoid this possibility and improve the quality of your show for your listeners.
Host your own Talk show, Internet Radio make it easy.
