Ubuntu – How to permanently disable the internal WiFi adapter

network-managernetworkingwireless

I recently installed a Linksys Wireless-N Notebook Adapter w/Dual-Band (WPC600N), which is working nicely via the PCMCIA slot; however, I cannot find where to permanently disable the internal WiFi adapter. Currently, I'm forced to manually disable it with each reboot.

Unless there is a hardware switch to turn it off, just blacklist the module.

You can find out which module is in use with this:

lspci -nnk | grep -iA2 net

...to blacklist a module, add blacklist module_name to /etc/modprobe.d/blacklist.conf
