Xperia Pro/Neo/V/L :: Connecting It With PC Via WiFi?

im trying to conecct to my PC via Wi.Fi, since it's bothesome to connect the USB cable each time i want to transfer something.I have a TP-Link wireless router to which my PC is connected via LAN and my phone via wireless, i have a Wi-Fi connection on my phone and the internet is working on it. Both PC and phone are in the same network (ex. 192.168.1.x, where x is the IP address for each device).What i can't manage to do i connect my PC and my pone via Wi-Fi, i followed the manual on page 111:[URL]The manual suggests the following:To pair your phone wirelessly with a computer using Media transfer mode:

1 Make sure Media transfer mode is enabled on your phone. It is normally enabledby default.

2 Connect your phone to the computer using a USB cable.

3 Computer: Once the phone name appears on the screen, click Networkconfiguration and follow the instructions to pair the computer.

4 When you are finished pairing, disconnect the USB cable from both devices.

The above instructions only work if Windows® 7 is installed on your computer and the computer is connected to a Wi-Fi® Access Point via a network cable. (i have win7 x64 and my PC is connected to the Wi-Fi router via LAN)The problem is i can't get past step 3, as soon as i connect my phone to the PC the PC Companion recognizes it and there is no Network Configuration options availible like the manual said there would be. When i go to the Connectivity settings it says "No trusted hosts". Do i need to port-forward some port, If yes i know how to do do it, but i don't know which port.
