I can't believe how dumb these guys. After all that years I want to clarify this topic.
You just want to use your phone's wifi card, like a USB device. And this is absolutely not possible in easy way.
Look, you must find a driver from depths of web (almost impossible) - which can seperate your Wifi Card from your device and connect it to your pc via phone motherboard's interface. Or you must create your own bootable application for your mobile phone - Which Your device can boot as only Wifi Card Adapter, PLUS to that it must be able to connect with USB to your pc. (It would seem like phone's download mode).
So able to do these two, you must be quite skillful software engineer or advanced coder. For a normal person this is impossible, my friend.
