[Bug 1514316] Re: 0bda:8172 Realtek WiFi works in Live environment but stops after installation


I followed the instructions on the page you linked and after booting
into the 4.4.0-rc2-custom kernel, the wireless card did work without
issue or additional drivers.

  0bda:8172 Realtek WiFi works in Live environment but stops after

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.

  wget http://launchpadlibrarian.net/37387612/rtl8192sfw.bin.gz
  gunzip rtl8192sfw.bin.gz
  sudo mkdir /lib/firmware/RTL8192SU
  sudo mv rtl8192sfw.bin /lib/firmware/RTL8192SU/
  sudo depmod -a or reboot
  sudo service network-manager restart

  After every reboot I have to run "sudo service network-manager
  restart" for wireless to work.
