Same wireless chip (and very similiar laptop); wireless never worked out-of-the-box both in Trusty and in Vivid; this is how I've always installed it:

  1. Download the drivers for the wireless chip from here;
  2. Open Terminal with Ctrl+Alt+T;
  3. Run cd ~/Downloads; unzip MT7630E-release.zip; cd MT7630E-release; sudo bash install

If the driver is installed to an UEFI managed system, Secure Boot should be disabled in UEFI settings to get the module loaded.

    A good one. +1. – Pilot6 Sep 20 '15 at 19:05
  • @Lancilnove You're welcome :) I've been struggling as well the first time because the original drivers from MediaTek won't compile on every kernel without some modifications. Luckily the guy who posted the tutorial did the job for us :) – kos Sep 20 '15 at 19:07
