Wifi Issues while JB - PS4 4.55

Hi,
Got PS4 4.55 . Want to Jailbreak. I'm using Wifi as my LAN Cable is too short..

I tried Al Azifs method from Github - (using Wifi Connection) but get error when Testing Internet Connection.

SSID: My Router
Obtain IP Address: Successful
Internet Connection: Failed

- Is it because Im setting up Internet on WIFI, If so, Is there another method where WIFI works?
