I have an HP laptop 7 months old (10 inch screen) I have been running Ubuntu on it for 6 months without any problems, yesterday the upgrade for Ubuntu 16-04 appeared which I eagerly accepted, after completing the download and set up I have 16-04 but sadly my internet is now disabled,I've tried the obvious things and some fixes on this site but to no avail. Any one out there who can help ??????

    Please [edit](http://askubuntu.com/posts/779465/edit) your question to include terminal results for `lspci -nnk | grep -iA2 net; lsmod | grep wmi` – Jeremy31 May 30 '16 at 12:54
  • Haven't a clue what all that means Jeremy31. – Ray Charsley May 31 '16 at 09:06
  • Open a terminal window using CTRL + ALT +t enter the command, press enter. The use mouse or touchpad to highlight results. Use right click menu to copy – Jeremy31 May 31 '16 at 14:39

  • The commands have a small L in them, not a 1 – Jeremy31 Jun 01 '16 at 08:40

Are you using a wireless connection?

If yes, used this tutorial to solve my problem.

(I did it after an upgrade in 14.04, but maybe it can work in your case too.)
