Default WiFi Hostpot

Hi Guys,

I recently bought F400S from Korea and using it in Turkey.

I dont have any problems for using 3g however i have big issue for the wifi hotspot. I can easliy connect any device to my G3 for wifi. However even the 3g works on G3 I cannot enter to Web from other devices. My laptop connects to G3 wifi, the connection seems good but cannot enter to web.

You think it is a hardware or software problem? How can i solve it?
