I booted my computer using an Ubuntu 15.10 64-bit Desktop live CD  and
wifi worked no problem. After installing Ubuntu 15.10 to disk, wireless
no longer works. I can see the wireless device using lsusb but it is not
an option to use in network-manager, and does not show up in
/etc/network/interfaces.

Bus 002 Device 003: ID 0bda:8172 Realtek Semiconductor Corp. RTL8191SU
802.11n WLAN Adapter

My computer does not have an airplane mode button. The wireless card is
not disabled that I can tell or from my own actions.
