Skoda Superb MK3 IV Wifi Connectivity

Hi, I imported Superb MK3 IV from Germany to Egypt. The car is fabulous, and everything is working OK except the WIFI and the wireless android auto.

I used my phone as hotspot and used the car WIFI setting to connect to the hotspot. The connection is successful, but it looks like the car doesn't has internet access with the connection. When I try to download the English version of the manual, it reports no internet connectivity message. 

When I try to register the car primary user, it just fails without meaningful error displayed.

Also wireless android auto it may connect once but it fails dozen time. Even with successful connection, it disconnects. The wired AA is working fine thought.

My infotainment system is Columbous.
