Ad-hoc connection to PC

Hey guys,
just asked myself if it could be possible to surf on the internet with my M8 with the internet connection of my Vista PC.
Just created an ad-hoc network on my PC and I could connect to it with my M8.
But i still have no connection to the Internet.
Opera always says "The access point does not exist, please check your settings".
My Pc is connected to the internet via LAN.

Maybe someone can tell what to do

*EDIT*
Ok, guys. Finally got it to work!
For those who want to know:
1. Create an Ad-Hoc connection on you PC
2. Connect to that network on your M8
3. Change the IP on your PC to:
192.168.0.1
255.255.255.0
4. Change the IP on your M8 to:
192.168.0.2
255.255.255.0
Gateway: 192.168.0.1
DNS: 192.168.0.1
5. Change the option on you PC LAN connection that other users can share this connecction.

Can't you just tun on WLAN then you have the internet?

or do you not have a wireless router?

No i do not have a wlan router *g*
Otherwise i would not try to go to internet by this way
So perhaps interesting for all the other who have no wlan router either

how do i change the ip of my meizu?

Go to Settings -->WIFI-->click on the connection a bit more right-->there you can change the ip
