|Not everybody has this Intel program of which you speak.|
Honestly, even if I did, I wouldn't use it. It's much simpler to just control your network interfaces directly as wanderer has suggested.
Control Panel >> Network and Sharing Center >> Change Adapter Settings
Right click on the appropriate adapter and select Enable/Disable from the pulldown menu that appears.
You wish to enable wireless so you'd right click on the wireless adapter and select "Enable" As per wanderer's advice, I would disable the wired adapter first. If for some reason you wish to change back to the wired, go back to the same spot, disable the wireless and enable the wired.
I have 3 network adapters on my PC at work and swap between them all the time this way. Our work laptop has both a wired and a wireless adapter and I regularly swap between the wired./wireless using this method. I've never used Intel, or anybody else's 3'd party software to control my network adapters.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
