[Bug 1514316] Re: Wireless Works On Live CD Stopped Working After Installation 0bda:8172 Realtek Semiconductor Corp. RTL8191SU 802.11n WLAN Adapter


Is the output from usb-devices useful if I cannot remove the other

The computer with this issue is an all-in-one touch PC mounted to my
wall. Most of the peripherals are USB based but the connections are in
the PC, not external to it. The touch controller, webcam, and wireless
card are built in but use USB.

  Wireless Works On Live CD Stopped Working After Installation 0bda:8172
  Realtek Semiconductor Corp. RTL8191SU 802.11n WLAN Adapter

Status in linux package in Ubuntu:

Bug description:
  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.
