I have a fresh install of 16.04 LTS on an HP Pavilion previously running Visa. The Ourlink wireless dongle worked with Vista but not with 16.04. (When I go to add a wireless network, no device is seen.) I have the disk with driver "rtl8821AU_linux_v4.3.14_13455.20150212_". I opened with package manager but am not sure it loaded. It also has an install file that just seems to open when I run in terminal "install.sh" I'm semi familiar with Ubuntu but no expert.

lsusb shows what is below. Bus 002 Device 005 goes away when I unplug the dongle.

  • worked perfectly – Dan May 29 '17 at 23:50
  • I rebooted and the connection is now gone. I can see wifi under network connections and there is what looks like a mac address. Settings look good but it does not see any wireless signals. Did I miss a step? I rebooted the router and another system on wifi is working. – Dan May 30 '17 at 1:53
  • Rerunning the re-compile gets me a connection again so am I missing some kind of save or load function? – Dan May 30 '17 at 2:08
  • Another reboot and it connects on its own so it is working but I'm not sure why – Dan May 30 '17 at 12:24
  • I suspect that, once you got it compiled and did the many updates, one of the updates was a newer kernel version, also known as linux-image. They will always require a recompile as I explain above. If my answer has been helpful, please accept it: askubuntu.com/tour – chili555 May 30 '17 at 12:33
