I have a Sony Vaio with an intel Pro/wireless 2200BG (calexico2) card that is broken. In windows I disabled this card and installed a USB wireless device (Realtek 802.11n WLAN adapter) which makes wireless connection possible. I cannot get a wireless connection in LUBUNTU because the computer keeps on trying to connect through the original (broken) hardware. How can I disable that original hardware. I tried blacklisting the driver for the Intel hardware in /etc/modprobe.d but unfortunately that seems to interfere with any wireless connection.
