I have little experience so bear with me.

I have the almost the same problem on my desktop and on my laptop.
While the cable is plugged I can see the wireless but when I unplug it there all gone.

I have searched all over, found similar issues but still can't work it out.

I am focusing on the laptop an HP intel core duo where under the hardware drivers I can see broadcom's proprietary driver.
