Bluetooth internet connection via PC

Hello everybody,  

I have a Computer with an internet connection and i would like to get internet on my ipod touch 4 via Blutooth. I was thinking of a connection like this: PC with internet connection ---> Bluetooth dongle ---> Ipod with bluetooth


Any help would be most welcome,

Thank you

(My Routers WiFi option is broken so please don't start saying "Why don't you use WLAN/WiFi?".)
